ChainMemory gives your AI agents persistent memory that belongs to YOU โ€” 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 โ€” 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.

    I like https://gottcode.org/focuswriter/ and have used it for years and years, you can configure the look and feel pretty extensively. Lots of ways to skin that cat (especially if like me you are a linux user) but focuswriter does everything I need, very little I don't and there is a frame/mindset shift to using the same tool for a specific task. - Source: Hacker News / 8 months ago
