# Teetra > Teetra is a studio of AI-first apps that puts builders' APIs inside every AI assistant (Claude, ChatGPT, Gemini, Copilot). It is both the holding company and the product. Teetra turns AI usage of your API into paying customers. Agents discover your API by what a user asks for, try it free on a budget you set, and convert into paid accounts that stay routed through you. The customer relationship stays yours. Onboarding is discovery with zero plumbing: nothing from Teetra is installed in your codebase, and there is no library or middleware to maintain. Teetra reaches only the endpoints you expose. For authenticated APIs your key lives in a secure connection, never in repository code, and you can revoke it at any time. Anything that mutates data is previewed and needs your approval first; read calls run without it. ## Properties - [Neemio](https://neemio.com): health.
