How to Add AI to Your Existing SaaS Application: A Practical Guide for 2026
"Should we add AI to our product?" isn't really the right question anymore. Most SaaS founders and product teams have moved past whether to add AI and are stuck on how — how to do it without a six-month rebuild, a runaway API bill, or a feature that looks impressive in a demo but nobody actually uses.
