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.

Snapdrop features and specs

  • Cross-Platform
    Snapdrop works across various platforms, including Windows, macOS, Linux, Android, and iOS, making it quite versatile for different users.
  • Ease of Use
    The user interface is simple and intuitive, requiring no installation or setup, which makes it accessible for non-technical users.
  • No Account Needed
    Users do not need to create an account to use Snapdrop, which speeds up the file-sharing process and enhances privacy.
  • Open Source
    Being an open-source project, Snapdrop allows users to inspect, modify, and improve the source code, fostering community trust and collaboration.
  • Peer-to-Peer
    Files are transferred directly between devices over a local network, which can result in faster transfer speeds compared to cloud-based solutions.

Possible disadvantages of Snapdrop

  • Limited to Local Network
    File transfers are limited to devices on the same local network, making it less useful for remote file sharing.
  • No Permanent Transfer History
    Snapdrop does not keep a permanent history of file transfers, so users cannot retrieve previous files shared after the session ends.
  • Security Concerns
    Despite encrypting data in transit, Snapdrop could still be vulnerable to security issues typical of peer-to-peer networks if not properly managed.
  • Lacks Advanced Features
    Compared to other file-sharing solutions, Snapdrop lacks advanced features like file versioning, cloud storage integration, and large file support.
  • Dependence on Browser
    Snapdrop functions through a web browser, which means users need a browser open to use it and may face compatibility issues with some browser versions.

Snapdrop Reviews

  1. A Complete waste of time from a 4 decade mac pro user

    Takes forever to send even small video files with high speed internet. Horrible documentation for transferring instructions. No option in the app menu to choose a destination folder. There's no way to compress all of your videos on an android to send to the Mac, even though that is suggested in their "features". And not 1 single video could I find in 2 hours of google searches that answered these questions. For a company touting such "ease of use", as a 40 year mac user, this was another waste of time app. If the company would like to contact me and answer these questions, if it is indeed an "easy, reliable app", I will gladly help them make a video that actually walks people through the problems I have encountered.

  2. Excellent way to share a folder with multiple files to another computer

    SnapDrop does an excellent job in sharing multiple files to another computer. Just zip/compress a folder with multiple files and select that zipped folder to send to the other computer or mobile device.

  • How to Transfer Files Between iOS and Android in 2025
    Snapdrop Snapdrop is mainly a browser-based service rather than a native mobile app, though some unofficial wrappers exist. It requires a modern web browser and uses WebRTC for peer-to-peer file transfers. Because it runs in a browser, an internet connection may be necessary. Snapdrop works best for sharing small files, while larger transfers may be slower due to browser constraints. The service is free and does... - Source: dev.to / 7 months ago
