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.

Our app puts three core values to the fore: simplicity, visualization, and consensus.

By creating an infinite canvas where cards, much like sticking notes, resemble a neatly organized collection of inter-related ideas. They serve as units of thoughts with clear borders, displayed on a squeaky-clean white canvas.

To preclude the document from becoming messy as the number of cards augments, we betted on functions that are clear-cut and intuitive. They include drag’n’drops; deep dive; tabs within a document; embedded pictures, videos, and links; sub-pages. As a result, the users get a well-organized, easy-to-navigate space.

Rather than providing bits and pieces of scattered information, the tool gives you a bird’s-eye view of the cards, creating the big picture.

Pillared by simplicity and visualization, the app offers a collaborative space for teams to work together in real-time, sharing cards and elaborating on ideas.
