ChainMemory gives your AI agents persistent memory that belongs to YOU — not to a single vendor.

Save a memory in ChatGPT, recall it in Claude or Gemini. Available via Chrome extension, MCP server (npm), or REST API. Every memory gets a cryptographic fingerprint and project states are anchored with Merkle proofs, so anyone can independently verify integrity — no trust required.

Memories consolidate into a structured Project Brain (decisions, milestones, risks) instead of a pile of raw notes. Multi-agent native: Claude, Cursor and GPT share one consolidated state. Free tier available.

  • Trying to understand who Tango.us is for?
    I've been using tango.us to record different workflows to share to my coworkers, for example:. Source: over 3 years ago
  • How to write a killer help document?
    - tango.us will forever be my greatest help article hack. It's free and has a super easy extension. It's cut my writing in half, if not more. Instead of writing things step by step, I just turn on Tango, go through the process, and everything is nicely documented. I typically edit the text to provide a little more detail, but besides that, it basically generates a help article in 5 minutes that's easy to export.... Source: over 3 years ago
