ChatExport is a production ChatGPT App built on the OpenAI Apps SDK and Model Context Protocol (MCP), running on Cloudflare Workers free tier. Users invoke it from inside ChatGPT, choose a format, and receive a download card rendered by a single-file React widget embedded directly in the worker response.
There is no backend database for chat content — every export is computed in memory and returned as a base64 file inside an ephemeral JSON-RPC response. Optional Google Drive OAuth tokens are encrypted at rest with an in-house WebCrypto AES-GCM helper. Five MCP tools cover export, preview, format discovery, Drive connection, and recent-export history.
A companion Firebase-hosted marketing site (chatgpteai.web.app) handles SEO, blog, sitemap, FAQ, and a Radix-driven Theme Customizer — making the project a complete reference implementation of the OpenAI Apps SDK, MCP, Hono, and edge-deployed single-file widgets.
