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.

  • Which synchronization tool are you using together with the pCloud Crypto Folder?
    FreeFileSync messed up my pCloud database a couple times at first (causing disappearing files in the Crypto Folder, mirroring of the same files over and over again). Pcloud support provided an easy way to fix the database. To fix the root cause, one needs to exclude FreeFileSync's temporary files from the backup: pCloud Drive > Settings > Backup/Sync Exclusions, exclude sync.ffs_lock and *.ffs_tmp.

  • Why are file backups so slow on Windows 11?
    As per Apprehensive_Arm_754 answer below, https://freefilesync.org is the solution to my particular problem, since it allows all kind of simple rules and logic to apply, so I can make sure that the copy only happens in one direction, and only ever by file date etc. Much appreciated.
