What are some underrated ways AI app developers can find early users?

Most AI developers seem to focus on Product Hunt, Reddit, X, Discord, and SEO. What other channels have worked for you when trying to get early users and feedback for an AI application? I've recently come across Pi Network, which appears to be encouraging AI app developers to build in its ecosystem and offers access to a large user community along with payment and app infrastructure. Has anyone here tried it or found other alternative distribution channels worth considering? submitted by /u/chmossie [link] [留言]
