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.

MOS features and specs

  • Lightweight
    MOS is designed to be lightweight, which means it has a minimal footprint and is resource-efficient, making it suitable for running on devices with limited resources.
  • Customizability
    The operating system allows for high customizability, enabling users to tailor it to their specific needs and use cases.
  • Open Source
    Being open source, MOS allows developers to inspect, modify, and enhance the code base, with the potential for contributing to its development.
  • Community Support
    As an open-source project hosted on GitHub, it potentially benefits from community involvement, where users and contributors can share ideas and support each other.

Possible disadvantages of MOS

  • Limited Documentation
    Like many open-source projects, MOS may suffer from limited documentation, making it harder for new users to get started or for developers to contribute effectively.
  • Niche Use Cases
    Due to its customized and lightweight nature, MOS might not support a wide range of applications or use cases compared to more mainstream operating systems.
  • Development Activity
    The level of active development and frequency of updates for MOS might fluctuate, which can impact long-term support and feature enhancements.
  • Compatibility
    Compatibility with other software and hardware might be a concern, limiting the use of MOS to specific tasks or environments.
