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.

For diary purposes, I'd suggest DayOne for iOS/Android and Journaley, a compatible program for PC. Journaley is free and open-source; DayOne is not (though I'm sure someone has an APK somewhere). Source: almost 4 years ago
There's even an unofficial open-source PC version of DayOne called Journaley. Apparently, there was also an old version called Day One Classic (but other than the old iOS version on my iOS 7 iPad going by that name, and an import option within Day One, I don't have any more info on it).
