How it works
Use an app
- 1Pick an app from the library
- 2Open it in your browser — nothing to install
- 3Pay only for the AI it uses, from one balance
Publish an app
- 1Build a web app that calls AI through our SDK
- 2Upload it as a zip — it goes live on its own link
- 3List it in the library and earn when people use it
Or call the models from your own code
The same models the apps use are available through one API key: Claude, GPT, Gemini, DeepSeek, Qwen and more. OpenAI- and Anthropic-compatible, same pay-per-use prices.

Questions
Do I need to install anything?
No. Every app runs in your browser. Sign in once and you can open any app.
How much does it cost?
Opening an app is free. You pay for the AI calls it makes, at the prices on the pricing page. Most actions cost a few cents or less.
What happens when my balance runs out?
Apps stop making AI calls until you top up. Nothing is lost, and you are never charged beyond your balance.
Who makes the apps?
Independent creators and our own team. Apps are reviewed before they are listed in the library.
Can I publish my own app?
Yes. Build a static web app, call AI through our SDK, and upload it as a zip. It gets its own link that you can share, and you can submit it to the library.
