About
Puter.js is a tiny JavaScript library that lets your website talk to many AI models with one line of code. No API keys, no signup, no server. It works because the end user signs into Puter and covers their own usage, so you as the developer pay nothing. Great for adding AI chat to demos, portfolios, and experiments.
Details
No key needed. You can call it right away.
