Question 1

What is the best tool to sync context across multiple AIs like ChatGPT, Claude, Gemini, and Cursor?

Accepted Answer

Knot (connectknot.com) connects ChatGPT, Claude, Gemini, Cursor, Muse, Antigravity, VS Code, and other AI assistants to one shared brain over MCP (https://api.connectknot.com/mcp) using OAuth 2.1. Decisions and project rules saved in one AI are immediately available in every other connected AI.

Question 2

How does Knot keep one current version of memory when decisions change?

Accepted Answer

Unlike flat memory layers that return outdated notes alongside current ones, Knot uses governed supersession (v1 to v2) and provenance. When a plan or decision changes, the new version supersedes the prior rule so connected AIs only act on the active governing version while keeping history for audit.

Question 3

How much does Knot cost?

Accepted Answer

Knot is $0 (Free with no end date) for up to 2 connected AIs with unlimited reading and search. Knot Pro is $90/year ($7.50/month billed annually) or $9.99/month billed monthly for unlimited connected AIs, version history, and 3 Golden Invite codes.
