Anthropic API key
Prompt editing runs against your own key. It is stored in this browser only and sent only to api.anthropic.com — there is no server in the middle. Create one at console.anthropic.com.
MCP bridge
Let Claude, ChatGPT or any MCP client measure and edit these models. Your AI talks to the server; the server hands each tool call to this window, which runs it on the models stored in this browser and sends the answer back. Its edits arrive as ordinary revisions you can undo. Because the models live only here, this tab has to stay open with the bridge on for your AI to reach them.
Storage
Your models, edit history, folders and constructs live in this browser’s database. Nothing is uploaded: your AI’s calls are relayed by the server to this window and run here. Clearing site data deletes everything, and it does not follow you to another browser or machine — keep a backup (below) if it matters.
Backup & restore
A backup is a single .zip holding every model, edit, folder, tag and construct, with the original files inside it. Keep one somewhere off this machine — clearing site data wipes the database, and it does not sync. Your API key is not included.
