What is ZeroAPI?
ZeroAPI is a completely free suite of browser-based AI tools for developers, researchers, and students. No signup. No API key. No cost.
I built it because I got tired of seeing powerful AI tools locked behind paywalls and complex API setups.

Why I built this
I'm an Assistant Professor of CSE in India and author of "Agentic AI Systems: Design & Engineering". My students needed access to AI tools but couldn't afford expensive subscriptions or figure out complex API setups.
So I built ZeroAPI – completely free, always.
