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.

Possible disadvantages of MarkNote

  • Limited Advanced Features
    Compared to more robust note-taking applications, MarkNote might lack some advanced features such as collaboration tools, version control, or extensive integration with other third-party apps.
  • User Interface Simplicity
    While simplicity can be beneficial, the user interface might be too basic for users who prefer a more feature-rich and visually appealing application.
  • Dependent on KDE Environment
    Although it integrates well with KDE, users not familiar with the KDE environment might encounter a learning curve, or it might be less appealing if they use other desktop environments.
