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.

Authy features and specs

  • Multi-device synchronization
    Authy allows users to sync their 2FA tokens across multiple devices, which provides a convenient way to access tokens from phones, tablets, and desktops.
  • Encrypted backups
    Authy provides encrypted backups of the 2FA tokens to the cloud, ensuring that users can recover their tokens in case of device loss or damage.
  • Offline usage capability
    Authy can generate 2FA codes even when the userโ€™s device is offline, providing access to tokens without requiring an active internet connection.
  • Desktop app available
    Authy offers a desktop application that allows users to manage and use their 2FA tokens directly from their computer, enhancing accessibility and usability.
  • Security features
    Authy includes advanced security features such as PIN protection and biometric login options, adding an additional layer of security to the 2FA tokens.

Possible disadvantages of Authy

  • Dependency on cloud service
    Authyโ€™s cloud-based backup and multi-device synchronization features create a dependency on their cloud service, which may raise privacy and security concerns for some users.
  • Limited customization options
    Compared to some other authentication apps, Authy offers fewer options for custom-tailoring the appearance and organization of the 2FA tokens.
  • Potential for lockout
    If users forget their Authy backup password or lose access to all trusted devices, they may have difficulty recovering their 2FA tokens, leading to a potential lockout of their accounts.
  • Initial setup complexity
    The initial setup process, which includes account verification and device synchronization, may be more complex and time-consuming compared to other simpler 2FA apps.
  • Limited platform support
    While Authy supports major platforms such as iOS, Android, and Windows, it does not have the same broad platform compatibility as some other 2FA solutions, potentially limiting its usability for some users.

ChainMemory features and specs

  • Cross-model memory
    Save in ChatGPT, recall in Claude, Gemini, Perplexity or Copilot
  • MCP Server
    Native integration with Claude Desktop, Cursor and any MCP client (npm)
  • Chrome Extension
    One-click save and context injection on any AI chat
