What you get
One link. Every assistant.
Write the setup once. Fob carries it into Claude, ChatGPT, Cursor, Copilot and Codex, and keeps the keys on &loop.
- One link, any assistantAdd the link and sign in. Nothing to install, no JSON config files, no keys on the laptop.
- Write once, use everywhereOne set of instructions and skills. &loop delivers them the way each assistant understands, and keeps up when they change.
- Profiles per project or client"Client A" gets their Jira and database. "Personal" gets your notes. Pick one when you connect.
- Your own data as toolsTurn a spreadsheet, database, API or &loop pipeline into a tool like "look up order status" without hosting a server.
- You decide what it can touchRead-only or read-write per assistant, per-tool blocks, approvals for risky actions, and a log of every call.
- Secrets stay out of the repoKeys live in an encrypted vault on &loop. Assistants use the tools; they never see the keys.
