ChatAPI turns plain English into a working MVP — real APIs, real code you own. No engineering team required.
No sign-up to start · free trial · your build carries over when you join
Ships on Next.js · TypeScript · Convex
Builds on the APIs you already trust
The whole build, handled.
You bring the idea. ChatAPI brings the APIs, the architecture, and the code — and hands it all to you.
Plain English in, real code out
Describe the product the way you'd explain it to a friend. ChatAPI returns a working codebase — not a wireframe, not a mockup.
It picks your stack — and explains why
No more Twilio-vs-the-other-one rabbit holes. ChatAPI chooses the right APIs for your idea and tells you the reasoning, like a senior engineer would.
Download everything
Every file, route, and webhook, packaged as a ZIP you can run locally. It's your code on a clean Next.js + TypeScript stack — no lock-in.
Ship to your own Vercel
Go from idea to a live URL on infrastructure you own. Bring your own custom domain when you're ready to put it in front of customers.
How it works
From a sentence to a codebase in three steps.
Describe it
Type your idea into the box. One sentence or one paragraph — whatever you've got.
ChatAPI assembles it
It selects the right APIs, writes the integration code, and generates a README that walks you through setup.

Founders, in their words.
Non-technical builders shipping real things, faster than they thought they could.
“I'm not a developer. I gave it a one paragraph idea on a Sunday and by Tuesday morning I had a working booking site with Stripe checkout. Took me longer to set up my Stripe account than to actually build the app.”
“We were quoted $48k for the v1 build. We used ChatAPI for two evenings and a Saturday and shipped something good enough to put in front of our first 12 patients. Not pretty in places — fixed those by hand — but the bones were right.”
“The thing I didn't expect: it kept telling me which APIs to use and why. I'd been going back and forth on Twilio vs MessageBird for a week and it just picked one and gave me reasons. Felt like talking to a senior eng for the first time in a while.”
“Not perfect. I had to redo the email templates and the file structure annoyed me. But it gave me a real codebase in a few hours and that's the part I was actually scared of. Everything else is just work.”
“I tried two other AI builders before this and the code was always weird or it would invent libraries that don't exist. This one used actual Stripe, actual Resend, the README was honest about what I had to set up myself. First tutor on the platform Monday morning.”
“We don't use it for production but it's the cheapest way I've ever found to validate a product idea. We've killed three ideas this quarter in like 4 hours each. Worth the $25 just for the things I now know not to build.”
Questions.
Do I need to know how to code?+
No. You describe what you want in plain English. ChatAPI chooses the APIs, writes the integration code, and hands you a working project with a README that walks you through the few keys you need to paste in.
What do I actually get?+
A real Next.js + TypeScript codebase — every file, route, and webhook — that you can download as a ZIP, run locally, and deploy to your own Vercel. It's your code, not a locked-in builder.
Is it free to try?+
Yes. Start building with no sign-up and no card. You get a free trial budget; sign up free to save your build, and upgrade to Pro ($10/mo) when you want the full downloadable MVP.
Which APIs can it use?+
Over 100 pre-vetted services — Stripe, Resend, Twilio, OpenAI, Plaid and many more. ChatAPI picks the right ones for your idea and explains why it chose them.
Will the code actually be good?+
It ships real, named libraries — actual Stripe, actual Resend — on a clean Next.js + TypeScript + Convex stack. It won't be perfect in every corner, and you'll polish some things by hand, but the bones are production-shaped.
Can I deploy what I build?+
Yes. Connect your own Vercel and ship to a live URL. On Pro you can point a custom domain at it and put it in front of real customers.
Your idea deserves to exist.
