## About

Tessryx gives an agent somewhere to build. From chat, it creates the data, logic, pages and scheduled jobs for a real website, API or internal tool, and Tessryx hosts them at a public URL on the user's own domain. No code is generated for the user to deploy and nothing needs to be run locally.

The main workflows the tools support:
- Author a JSON Schema, then datafiles validated against it. The same schema generates an editing interface, so a non-technical person can maintain the content afterwards without an agent.
- Author workflows that return HTML or JSON, and bind them to public URLs as dynamic endpoints with edge caching. One endpoint serves both a rendered page and the API routes that page's own JavaScript calls.
- Define parameterized HTTP calls to external systems, with credentials held as write-only secrets the assistant can reference but never read.
- Schedule workflows on a cron or interval so data recomputes on its own.
- Claim and verify a custom domain and serve any of the above from it.

Authentication is OAuth 2.1; there are no API keys for the user to manage.

## How to use

1. **Add it in ChatGPT** Open Tessryx in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick Tessryx, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.

## Example prompts

- "I want a live landing page for my business, let's iterate until I love it."
- "Make me a page that updates itself every morning without me touching it."
- "Turn my spreadsheet into a live page my team can edit without asking me."
