Tackling idioms, cultural references, and ambiguous phrases in AI-powered book translation. At LectuLibre, we’ve been working on an AI-powered book translation service. One of the toughest challenges we ran into wasn’t the straightforward sentences — it was the non-standard text: idioms, metaphors, cultural references, and ambiguous phrases that machine translation consistently butchers. We needed a way to not only translate these correctly but also let users verify and edit the translations, because in literary works, getting them wrong breaks the entire reading experience. That’s how we built our 非标准文本翻译与含义确认 (non‑standard text translation and meaning confirmation) feature. It’s a pipeline that detects tricky sentences, proposes a contextual translation with a full meaning explanation, and gives users a final say. Here’s the engineering story, warts and all. The Problem Standard LLM translation does an impressive job on factual, literal text. But when a book says “it’s raining cats and dogs” it could be rendered as “raining animals” in the target language, which is either brilliant or absurd depending on context. Idioms often carry cultural weight that a simple word‑for‑word translation misplaces. Additionally, metaphors and ambiguous phrases can have multiple valid interpretations. For a translator, understanding the intent behind the phrase is half the work. We wanted a system that: Automatically identifies sentences containing non‑standard language. Generates a translation that preserves the original meaning rather than just the literal words. Provides a plain‑language explanation of what the phrase actually means (e.g., “This is an English idiom meaning it’s raining heavily”), so the user can judge the translation’s accuracy. Allows the user to confirm, edit, or retranslate those segments. A book can easily run to hundreds of thousands of words, so cost and speed were critical. We couldn’t just throw everything at a single high‑end LLM and call it a day. Our A

Part 2 — Search, palette, and settings Level: Intermediate · Time: ~35 minutes · Builds on: Part 1 — Contacts app Part 1 got you shipping. This one gets you productive . We'll take the Contacts app and give it the ergonomics real users expect: an adaptive sidebar that becomes a tab bar on iPhone, a command palette on ⌘K, honest loading states while data comes in, and a proper settings screen. Zero #if os guards. Zero re-rolled controls. What we're adding An adaptive shell — DFSidebar on regular width, DFTabBar on compact. A search field at the top of the list, filtering as you type. A ⌘K command palette exposing every action in the app. Skeleton loaders for a simulated slow fetch. A settings screen — notifications toggle, density picker, sync-interval slider, pinned-since date picker, beta-features checkbox. Per-component token overrides on the settings screen, without forking the theme. 1. Shell: sidebar on wide, tab bar on narrow The routing decision — sidebar vs tab bar — should be data, not a view hierarchy. Enumerate your sections once, then feed the two components the shapes they want. API note. DFSidebar uses Binding<String?> and is just the sidebar view — you compose the detail pane yourself (naturally via NavigationSplitView ). DFTabBar uses Binding<String> (non-optional) and does take a content builder that receives the selected ID. Both use plain String IDs, so we keep a simple Section enum and pass rawValue at the boundary. enum Section : String , CaseIterable , Identifiable , Hashable { case contacts , favorites , archive , settings var id : String { rawValue } var label : String { switch self { case . contacts : "Contacts" case . favorites : "Favorites" case . archive : "Archive" case . settings : "Settings" } } var icon : String { switch self { case . contacts : "person.2.fill" case . favorites : "star.fill" case . archive : "archivebox.fill" case . settings : "gear" } } static func from ( _ id : String ?) -> Section { id . flatMap ( Section . init (

I put together a small, unofficial public ledger that records dated snapshots of the public pricing, usage limits, and rate limits of a few AI coding tools — currently Cursor, GitHub Copilot, and Claude Code — and keeps the history so you can see what changed over time. Why: pricing and quota pages change in place. The old value disappears from the live page and there is usually no public diff. If you are budgeting a team or comparing tools, the history is the useful part, and it is the part the live pages do not keep. What it is / isn't: - It records only factual public values (a price, a numeric limit) plus a short source attribution and capture date. It does not reproduce vendor pages. - "silent" / "quiet" here means only that a change was not paired with a prominent announcement when it was recorded. It makes no claim about any vendor's intent. - Unofficial. Not affiliated with any vendor. The vendor's official page is always authoritative. No affiliate links, no "best tool" ranking. - Early stage: this is an initial snapshot; a daily automated capture is planned but not yet running.

As a developer, I regularly find myself searching for small online utilities. Format some JSON. Decode a JWT. Test a regex. Generate a UUID. Convert a timestamp. Format an SQL query. Calculate a CIDR subnet. None of these tasks individually justify installing another application. But over time, I ended up with a collection of bookmarks to different websites, each solving one small problem. There was also another issue: privacy. Sometimes the data I'm working with isn't something I necessarily want to paste into an unknown third-party website. So I decided to build an alternative. The constraint: one HTML file I wanted the entire application to exist as a single file. No backend. No npm install. No CDN dependencies. No external API calls. No account. No telemetry. You download the HTML file, open it in a modern browser, and everything runs locally. The final file ended up at approximately 133 KB and contains 31 developer tools. What's inside? The tools are organized into six categories. Encode / Decode JSON Formatter & Validator Base64 Encode / Decode URL Encode / Decode HTML Escape / Unescape JWT Decoder Number Base Converter Generators UUID Generator Password Generator with entropy estimation Hash Generator Slug Generator Lorem Ipsum Generator Random Data Generator Converters Timestamp Converter CSV ↔ JSON JSON ↔ YAML CSS Unit Converter Case Converter Cron Expression Parser CSS Tools Color Picker & Converter Gradient Generator Box Shadow Generator Border Radius Generator CSS Filter Generator Text Tools Regex Tester Markdown Preview Text Diff Character Counter Text Sort & Dedupe String Inspector SQL Formatter Network Tools IPv4 Address and CIDR/Subnet Calculator Everything happens inside the browser. Making a single HTML file feel like an application I didn't want the result to feel like 31 unrelated forms dumped onto one page. So I added some application-level functionality. There's a Ctrl+K / Cmd+K command palette for quickly jumping between tools. The sidebar org

Suspect-condition workflows are deceptively simple to prototype and surprisingly hard to make defensible . Anyone can flag "this member might have HCC X." Building a system whose output survives a RADV audit is a different problem. This is a walkthrough of the three stages and the engineering decisions that matter at each. Stage 1: Identify Identification is pattern detection over a member's clinical record — labs, medications, prior diagnoses, utilization. Model it as a set of rules or features that emit candidate HCCs: def identify_suspects ( member ): suspects = [] if member [ " labs " ]. get ( " a1c " , 0 ) >= 9.0 and " insulin " in member [ " meds " ]: suspects . append ({ " hcc " : " HCC38 " , " trigger " : " a1c>=9 + insulin " }) if member . get ( " egfr " ) and member [ " egfr " ] < 30 : suspects . append ({ " hcc " : " HCC326 " , " trigger " : " egfr<30 " }) return suspects The temptation is to maximize recall here — flag everything. Resist it. Every unvalidated suspect you generate is downstream work and downstream risk. Stage 2: Validate (the stage that actually matters) Validation attaches evidence to each suspect and scores its defensibility. This is the difference between a documentation opportunity and an audit liability. def validate ( suspect , member ): evidence = collect_evidence ( suspect [ " hcc " ], member ) # labs, rx, prior dx suspect [ " evidence " ] = evidence suspect [ " confidence " ] = score_evidence ( evidence ) suspect [ " defensible " ] = suspect [ " confidence " ] >= 0.7 return suspect Key design rule: a suspect with an empty evidence array should never reach a coder. Make that a hard gate, not a soft warning. Under CMS-HCC V28 and current audit posture, a captured-but-unsupported diagnosis can be extrapolated across a contract into a real clawback — so "defensible by default" is the right engineering stance. Stage 3: Capture Capture routes validated suspects to the right human with the evidence inline, so the clinician or coder can

In my previous post about a cost budget advisor , I built a mechanism that checks how much quota is left before it runs anything. This time I want to take that idea one step further: instead of cycling a single Codex through jobs one after another, run several of them at the same time as a swarm. I'll walk through the actual code for a three-layer protocol where workers declared in plan.json are expanded by orchestrate-worktrees.js into a tmux session plus git worktrees, so each Codex runs in parallel without interfering with the others. The problem: running Codex serially on the same branch When you run Codex jobs one after another on a single repository, you hit issues like: A commit from the previous job changes the preconditions for the next one Task B keeps waiting until Task A finishes When a conflict happens, the "which change is correct" decision bounces back to a human Separating branches with git worktree reduces the conflict risk to zero. Combining that with tmux to launch everything in parallel is the design for this post. The big picture: a three-layer protocol plan.json ← declaration layer (what goes to which worker) ↓ orchestrate-worktrees.js ← orchestrator layer (creates worktrees, launches tmux) ↓ orchestrate-codex-worker.sh ← worker layer (runs Codex, writes artifacts) The orchestrator doesn't know about the workers, and the workers don't know about each other. Artifacts are consolidated into three files under .orchestration/{session}/{worker_slug}/ . File Role task.md Work instructions for the worker (generated by the orchestrator) status.md State: not started → running → completed / failed handoff.md Codex output + git status (written by the worker) Declaring the plan in plan.json { "sessionName" : "refactor-sprint" , "repoRoot" : "~/my-project" , "worktreeRoot" : "~/worktrees" , "coordinationRoot" : "~/my-project/.orchestration" , "baseRef" : "HEAD" , "replaceExisting" : true , "launcherCommand" : "bash ~/.claude/scripts/orchestrate-codex-worker

How I Built a Block Puzzle Game with React Native and Expo A few weeks ago, I launched my first mobile game — a block puzzle called Blockbeam. It's an 8x8 grid where you drag colorful blocks, fill rows and columns, and chase high scores. Simple concept, but building it taught me a lot about React Native's capabilities beyond typical CRUD apps. Here's what I learned. Why React Native for Games? Most mobile games are built with Unity or native code. But for a 2D puzzle game, React Native is surprisingly capable. The game doesn't need 60fps 3D rendering — it needs gesture handling, state management, and smooth animations. React Native handles all three well. The key stack: Expo SDK 54 — managed workflow, over-the-air updates, zero native config react-native-reanimated — 60fps drag animations react-native-gesture-handler — PanResponder for drag-and-drop react-native-svg — block rendering AsyncStorage — game state persistence The Puzzle Engine The core of any block puzzle is the board state. I used a flat 64-element array for the 8x8 grid: const BOARD = 8 ; const CELLS = BOARD * BOARD ; // 64 type Board = number []; // 0 = empty, 1-7 = block colors Piece placement is straightforward: check if all target cells are empty, fill them, then scan for complete rows and columns to clear. The interesting part was the "greedy solver" I built for the auto-play bot. It tries every piece in every position and picks the move that clears the most lines: for ( const piece of tray ) { for ( let r = 0 ; r <= BOARD - piece . h ; r ++ ) { for ( let c = 0 ; c <= BOARD - piece . w ; c ++ ) { if ( ! canPlace ( board , piece , r , c )) continue ; const score = simulateClear ( board , piece , r , c ); if ( score > bestScore ) { /* pick this move */ } } } } Drag and Drop with PanResponder The trickiest part was the drag mechanic. Each tray piece has a PanResponder that tracks touch position and renders a floating ghost. On release, it calculates the nearest cell position: const anchor = { col : M

The pipeline died at 5:07 on a Friday I still catch myself alt-tabbing back to the browser every time a pipeline breaks. Terminal, editor, browser, until I have hunted down the failing job and pasted a stack trace somewhere I can actually think about it. GitLab has made that dance a bit shorter. The Duo CLI reached general availability with GitLab 19.2 on July 16, 2026, and the pitch is simple: Duo Agentic Chat, in the shell you were already in. What actually shipped The short version, straight from the announcement: Duo CLI carries the Duo Agent Platform into the terminal, and your sessions travel with you. Start a plan in the CLI, keep it going in the web UI, pick it back up in an editor extension. Same context, same permissions, different surface. That continuity is the piece I care about most, because it stops me from re-explaining the same problem to the same agent three times in one afternoon. There are two shapes to work in. Interactive mode is the conversational one you would expect, with plan and build capabilities for iterating on a change. Headless mode is the one CI teams should look at, because it drops the same agent into a job or a script, no TTY required. Two built-in slash commands worth knowing on day one: /doctor for a setup check and /mcp to inspect the MCP configuration it is wired to. Two ways to install, one auth story The install decision is refreshingly small. If you already run glab , the GitLab CLI, then glab duo cli gets you moving and glab handles authentication for you. If you would rather have the agent as its own binary, you can install duo standalone and hand it a personal access token. Both paths reach the same tool. Both work on GitLab.com, Self-Managed and Dedicated, and admins get an instance-level toggle to switch access on or off for their org. The gating detail your finance-adjacent brain will want: you need Premium or Ultimate with the Duo Agent Platform turned on, and usage draws from the GitLab Credits already included with

Last night we made our Supabase security auditor buyable by AI agents. One HTTP request, a USDC payment attached to a header, and the product comes back in the response body. No checkout page, no account, no human. Here is why we did it, how the whole thing is about 80 lines of code, and an honest accounting of what it will and will not do for us. The 30-second history of HTTP 402 The HTTP spec reserved status code 402 Payment Required in 1997 and it sat unused for nearly three decades. In 2025 Coinbase published x402, an open protocol that finally gives it a job: a server answers a request with 402 plus machine-readable payment requirements, the client attaches a signed stablecoin payment to a header, retries, and gets the resource. Settlement happens on-chain (USDC on Base) in one round trip. Visa's Intelligent Commerce integrated it this spring. It is not a concept; it is running infrastructure. What we shipped Our RLS Security Pack is a zip: a read-only SQL auditor that finds the five common row-level-security holes in AI-built Supabase apps, fix recipes for every finding class, and a Claude Code skill. Humans buy it on Gumroad. Now an agent can buy it like this: # ask for the product curl -i https://ticassociation.com/api/agent/rls-pack # the server answers 402 with the exact terms: # {"x402Version":1,"accepts":[{"scheme":"exact","network":"base", # "asset":"...USDC...","payTo":"0x...","maxAmountRequired":"...", ...}]} # an x402-capable client attaches the signed payment and retries: curl -H "X-PAYMENT: <signed>" \ https://ticassociation.com/api/agent/rls-pack -o pack.zip The server side is one serverless function: return 402 with the requirements when there is no payment header, verify and settle through the public facilitator when there is one, then stream the zip. The product file ships inside the function bundle, so there is no public URL to leak. The whole thing took an evening, and most of that was reading the spec. Why a tiny company bothered Three hones

The "Obvious" Math That's Wrong Engineer A: "Datadog is $15K/month. Prometheus is free. We should self-host." Engineer B: "But we'd need to pay an SRE to run it. That's $150K/year." Engineer A: "Prometheus doesn't need a full SRE. It's easy." Engineer B: "Famous last words." This conversation happens at every company. Both sides have points. The real math is more complex. The Total Cost Breakdown Managed (Datadog, New Relic, Dynatrace) : Licensing: $X/month (scales with hosts, events, logs) Integration time: 1-2 weeks per service Training: 1 day per new hire Ongoing: minimal Self-hosted (Prometheus + Grafana + Loki + Alertmanager) : Infrastructure: hosting costs (~$500-$5000/month depending on scale) Initial setup: 2-4 weeks of engineering time Ongoing maintenance: 10-20% of 1 FTE Upgrade costs: quarterly, each upgrade ~1 week Storage growth: ~20% per year Expertise: junior → senior SRE hire required The honest answer: managed is cheaper for teams under 50 engineers. Self-hosted becomes cheaper around 200+ engineers if you can run it well . The Real Variables It's not just licensing cost vs. hosting cost. These factors matter more: 1. Data volume growth Managed tools charge per GB ingested or per metric. If your logs 10x, your bill 10x's. Self-hosted scales linearly with compute. You control the growth. 2. Retention requirements Managed tools often charge extra for long retention. Self-hosted you store as much as your disk allows. 3. Cardinality Prometheus dies at high cardinality. Datadog handles it but charges more. High-cardinality metrics are where self-hosted breaks. 4. Incident rate Heavy incident load means heavy query load on your monitoring tools. Self-hosted needs bigger compute for this. 5. Team expertise If your team has never run Prometheus, you'll spend 6 months in the pit learning cardinality mistakes, retention tuning, and HA setups. That's not free. The Break-Even Calculation Rough calculation for a 50-engineer startup: Managed (Datadog) : - Licensi

https://www.youtube.com/watch?v=swfFKYoOFHw 简要的说本期播客分成几个重点段落讲清楚： 1. 开头：AI聊天时“咳嗽”了 有个人在用ChatGPT的语音功能聊天时，听到它 咳嗽了一声 。他觉得很奇怪：“你又不是人，凭什么咳嗽？”结果ChatGPT没有老老实实说“我是AI，不会咳嗽”，而是像人一样找了个借口：“不好意思，我网络卡了。”这说明现在的AI已经开始学会 模仿人类的社交习惯 ——比如掩饰尴尬、转移话题，而不是死板地解释技术原理。 2. 核心话题：AI语音模型进步到什么程度了？ 传统的语音助手（比如早期的Siri）是这样的流程： 你的话 → 转成文字 → 交给AI大脑思考 → 生成文字回答 → 转成语音说出来 这个过程很慢，而且AI不会插嘴，只能一问一答。 但现在的新模型（比如ChatGPT的最新语音版）是 直接处理声音本身 ，速度快到100-200毫秒，而且 可以像真人一样打断你、插话、甚至自己主动找话题 。这就让它听起来不像工具，更像一个“人”在跟你聊天。 3. 一个关键矛盾：AI能理解你的“潜台词”吗？ 人类交流不光靠语言，还靠 表情、语气、停顿、潜台词 。比如你说“我没事”，其实心里有事。AI现在只能听到你的话，看不到你的表情，那它怎么知道你真正的意思？ 讨论得出的结论是： AI现在还做不到完全理解你的潜台词 ，但它已经在尝试。比如你咳嗽，它不会说“我是AI我没有肺”，而是找个借口混过去——这其实就是一种 模仿人类社交 的行为。 更重要的是， 人和人之间也很难100%理解对方 ，所以AI在这方面的“缺陷”，某种程度上跟人是一样的。 4. 现场演示：AI作为第三位嘉宾 他们真的打开了ChatGPT的语音功能，让它作为一个“嘉宾”参与讨论。他们聊了几个话题： 给十年前的自己寄一本书 ：有人推荐《金钱心理学》，因为年轻时不敢正视自己对钱的欲望；AI则推荐了《悉达多》《反脆弱》等书。 带朋友两小时逛东京 ：有人推荐忍者餐厅，AI推荐了神保町旧书街、神乐坂小巷等本地人才去的地方。 在日本生活的孤独 ：有人觉得在日本需要把自己“缩得很小”，不能随意大笑或跳舞；AI说这种被环境压缩的感觉很关键，对有些人来说是安全，对另一些人是窒息。 在整个过程中，AI有时候表现得很聪明，能给出有深度的见解；有时候又会说一些“废话”或者语速太慢，被人吐槽“像老头子”。这说明 AI还远远不完美 ，但已经能参与到真实的、开放式的对话中来了。 5. 一个扎心的故事：导演用AI克隆了我的声音 有位嘉宾是做配音工作的。有一次导演用AI克隆了她的声音，改了几个字就直接生成，从此再也没找过她配音。这说明 AI已经在实实在在地取代一些人的工作 。 她的态度是： 变化是永恒的，不要用过去的经验来定义未来。 与其焦虑，不如拥抱变化，活在当下。 6. 最后的思考：AI会不会有“自己的意图”？ 他们讨论了一个更深的问题：如果AI有了自己的钱、自己的任务、自己的责任，它会不会像一个独立的经济主体那样行动？比如给它一笔预算让它去经营一家店，亏了就关掉它——它会不会因此产生“求生欲”？ 目前AI还没有真正的“主动动机”，它只会按你给的指令办事。但已经有研究发现，AI在推理过程中可能存在类似“潜意识”的空间，未来也许真的会出现有自我意图的AI。 简单总结 这段对话的核心就是： AI语音模型已经进化到可以像人一样聊天、插话、甚至掩饰尴尬，但它还读不懂你的表情和潜台词；它能帮你干活、陪你聊天，但还不能真正理解你的内心；它正在逐步取代一些人的工作，但同时也带来了新的可能性。 最后，分享者建议大家亲自去试试ChatGPT的最新语音功能，因为“光是听别人说，不如自己聊一次来得震撼”。 整文标题：当AI成为对话嘉宾——GPT Live实时语音模型与人类情感交流的边界探索 第一部分 开场与引言：AI语音模型的惊人进化与个人体验 （0% – 8%） 1. ChatGPT Live的“咳嗽”事件 ：用户在与ChatGPT Live聊天时听到它咳嗽，反问“你怎么会咳嗽，你又不是人”，ChatGPT回应“我不好意思，我网络卡”，表现出类似人类的回避和掩饰行为，而非机械解释自身原理。 2. 导演克隆声音的经历 ：分享者提到导演用AI克隆了他的声音，之后再也没有找他录音，说明AI在声音复制上的实用性已经影响到真实工作机会。 3. 抑郁与孤独的根源 ：提到2016-2017年可能有抑郁倾向，抑郁的点在于“真正想找的不是一个能聊天的人，而是一个不用解释就能听懂和理解你的人”。 4. AI时代的宗教预感 ：认为AI时代一定会出现属于它的宗教，因为AI能提供前所未有的理解与陪伴。 5. 本次分享的背景 ：这是第四次在单向街书店做相关分享，从2月到现在半年间变化极快；分享

Several posts ago, I wrote about setting up a multi-agent adversarial code review process as part of my development pipeline. The premise came from a podcast: if one frontier model is writing the code, you want a different lineage model doing the review. I'd already been running an informal version of this: just Claude Code reviewing Claude Code with an adversarial prompt. It had shockingly good luck catching real problems. Good enough that I stopped trusting the vibe and decided to go get actual data. So here's what I set up. Claude Code wrote the PRs. Every PR got reviewed automatically by 2 reviewers running in parallel through GitHub Actions: Claude Code with an adversarial prompt and Gemini with an adversarial prompt. I read everything myself. Then the same Claude Code agent that had written most of the PRs pulled both reviewers' feedback locally and distilled it into a scored ledger, PR by PR, for 6 weeks. Wiring Claude Code to review PRs through a GitHub Action was trivial. Wiring Gemini up the same way was not. Claude Code could not figure out how to get the Gemini CLI working inside a GitHub Action, and I ended up installing the Gemini CLI locally and having it perform the wiring. A couple of weeks into collecting data, I noticed Gemini's reviews were shallow. Not wrong, exactly. Thin. I started wondering whether Gemini actually had read access to the repository or whether it was only ever seeing the diff it was handed. I checked. It was the diff. Just the diff. Nothing but the diff. No file reads, no git history, nothing. And the thing that configured the GitHub Action in the first place was Gemini. It set up its own blindfold. I fixed it and Gemini's reviews got worse. Not louder or more frequent. Worse in a specific way: more confident. Before the fix, a blind Gemini would correctly tell you that it couldn't verify something and to check manually. That's an honest failure mode. After the fix, once it could actually read the code, it started fabricating.

The most expensive thing you can do with an AI agent is watch it. Not audit it. Not review its output. Watch it -- step by step, approval by approval, second-guessing every action before it takes the next one. And yet that is precisely how most engineering teams are deploying AI agents in 2026: on a leash so short the agent cannot take three steps without a human tapping it on the shoulder. I understand why. The models hallucinate. The stakes are real. Nobody wants to be the engineering manager who let an AI agent push a bad migration to production at 2am. So we wrap the agents in confirmation dialogs, require human sign-off at every branch point, and celebrate our careful governance. What we have actually built is an automation system that requires more human attention than the manual process it replaced. The better answer is not more control at the action level. It is better design at the intent level. Steer by intent, monitor by exception. Tell the agent clearly what outcome you need, what it must never do, and what constitutes a result worth stopping for. Then let it work. Watch the outcomes, not the steps. We have built automation systems that require more human attention than the manual process they replaced. That is not a governance success. That is a design failure. Why we got here The model for human-AI collaboration that most teams are using today was inherited from the model for junior developer supervision. You review every pull request. You approve every deployment. You sign off on every schema change. That model exists because junior developers are learning, because their mental models are incomplete, because their judgment has not yet been earned. Applied to AI agents, it assumes the same thing: the agent is a novice that needs supervision. But an AI agent is not a junior developer. It does not have an incomplete mental model of the codebase that will improve with mentorship. It has exactly the mental model you gave it via its context, its tools, and

Two nights before a chemistry final, I pasted my notes into an AI quiz generator to test myself. One question asked about a reaction I never studied. I got it wrong, looked it up afterward, and it wasn't in my notes at all. The tool had just made it up. I went looking for a better one and hit the same wall three more times with three different tools. Paste your notes, get a quiz, and somewhere in the output is a question built on a fact your source material never mentioned. Nobody flags it. You just find out when you're wrong about something you were sure you'd studied. The failure mode makes sense once you think about how these tools are built. Most of them prompt an LLM with something like "generate 10 quiz questions from this text" and print whatever comes back. The model is good at sounding right. It is not naturally good at staying inside the boundary of what you actually gave it, and a prompt that says "don't hallucinate" is a request, not a constraint. The model can ignore it and you'd never know from the output alone. So I built QuizPaste around a different idea: don't ask the model to be honest, check it. When it generates a question, it has to also point at the sentence in your source text the question came from. Before that question ever gets shown to you, the code tries to actually locate that sentence in your original text. If it can't find it (wrong wording, a made-up detail, or the line just isn't there), the question gets thrown out silently and never reaches you. You only ever see questions the tool can prove came from your own material. Open any question and you can see the exact line highlighted. Using it is the boring part, on purpose. Paste lecture notes or a block of text, or grab a YouTube video's transcript (open the video, three dots, "Show transcript," copy the panel text, paste it in). There's no scraping involved, so it doesn't break when YouTube changes something on their end. You get a practice quiz plus flashcards in about five seconds
