ChainMemory gives your AI agents persistent memory that belongs to YOU — 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 — 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.
ChainMemoryOry is recommended for software developers, cloud-native application architects, and IT security teams looking for a customizable and scalable IAM solution. It's particularly well-suited for enterprises with complex access management needs, SaaS providers, and any organization prioritizing security and privacy in their applications.
