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.

It is also suitable for privacy-conscious users who require encryption and for those who appreciate open-source platforms where they can contribute to the software's development.

I can also recommend Trilium Notes [1], which I have been happily using for years. It's currently in "maintenance mode", which I personally see as a feature (no risk of bloatware). Self-hosted, great webapp, optional native clients and works offline. https://github.com/zadam/trilium. - Source: Hacker News / over 1 year ago
Tried Obsidian for a while, loved a lot about it, but....mmm. Obsidian out of the box is a bit limited; plugins are great and add tons of features, but then you start hitting issues with plugin maintainers abandoning plugins you rely on, or needing to make a decision between three different plugins that all do the same thing slightly different.
