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.

  • What app do you use?
    In the past I used to use an online app called DIARIOAPP (before they went to more of a subscription model); I also used Microsoft Word before that. More recently I've been trying out Microsoft One Note Journaling with One Note. I have an iPad, an Android cell phone, and a Windows computer--so I prefer a tool that is muli-platform. I've been using Peter Pauper blank books for visual journalling. Source: over 3 years ago

  • Storybook
    I have been a long-advocate for having a meaningful connection through self-reflection. Having a digital journaling app to log events, places, moods, and self-reflections from different points of view would fulfill my personal pursuits of journaling experience. While some journal apps I have seen simply record special memories and events, some focus more on mental health, mindfulness and self-care. I have decided... - Source: dev.to / about 5 years ago
