no-cost-ai

Why we included this project

This is a hand-maintained index rather than software you install, and its value is mostly practical: it saves you from clicking through half a dozen signup walls to find out which free AI services actually work. The list groups free offerings by chat, media, voice, and developer APIs, and notes the free models each one exposes plus any usage limits, so you can tell a no-signup chat interface apart from a signup-gated API endpoint before investing integration time. That makes it handy for developers and researchers prototyping on a tight budget, or anyone who wants a quick survey of what the current free tier really covers. It's community-maintained, so links and availability drift over time; spot-check anything you plan to rely on.
