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.

Hydrus features and specs

  • Comprehensive Tagging System
    Hydrus Network offers a robust tagging system, allowing users to organize and search through their media collections efficiently. This decentralizes the process of media management, making it highly customizable.
  • Decentralized Metadata Management
    The platform allows for decentralized metadata management, where users can share tags and resources with others. This improves data organization and sharing among different users while maintaining a personal collection.
  • Supports Multiple Media Formats
    Hydrus supports a wide range of media formats, ensuring versatility in handling various types of content like images, videos, and audio files. This eliminates the need for additional software to manage different media types.
  • Automation Capabilities
    Hydrus Network provides automation tools that help streamline the process of downloading and organizing media files. This reduces the manual effort required in managing a large collection.
  • Open Source Community
    Being open-source, Hydrus Network encourages community contributions which lead to improvements and new features being added regularly. This ensures that the software evolves to meet user needs.

Possible disadvantages of Hydrus

  • Steep Learning Curve
    For new users, the complexity of setting up and using the software can be intimidating. The learning curve may be steep for those unfamiliar with decentralization concepts and extensive tagging systems.
  • Resource Intensive
    Running the Hydrus Network may require significant system resources, especially when handling a very large collection. This can pose issues for users with low-end hardware.
  • Privacy Concerns
    Sharing tags and resources with other users over the network may raise privacy concerns, as metadata and potentially sensitive tagging information are disseminated across the network.
  • Limited Support and Documentation
    While the software is supported by an active community, official documentation and support are somewhat limited. This can make troubleshooting and learning new features more challenging.
  • UI/UX Challenges
    The user interface and user experience might not be as polished or intuitive as commercial software alternatives, potentially leading to a less smooth user interaction.

Hydrus mentions (9)

  • I need some pointers on cataloging audio files
    This may be useful: https://hydrusnetwork.github.io/hydrus/. Source: about 4 years ago
  • Searching for a media tagging website like Tagspace but self-hosted and free
    Hydrus? It's not quite true "self-hosted" (more of a standalone program with the ability to be configured to accept external api requests) but with the api and external programs set to interface with it, you can sort of set it up that way. https://hydrusnetwork.github.io/hydrus/. Source: about 4 years ago
  • Embed url into downloaded file
    If you want a concrete recommendation, all I can say without knowing exactly what you're doing is: you should at the very least consider solutions other than editing the file. This could mean sidecar files (e.g. info.txt), containers with metadata (e.g. warc), database applications (e.g. hydrus, even though it's a mess), etc. Source: over 4 years ago
  • Image library sorting solution.
    Hydrus (https://hydrusnetwork.github.io/hydrus/)? Not necessarily self-hosted but it does have a docker image, and I think there's ways to turn it into a self-hosted solution (hydrus.app comes to mind). Source: about 5 years ago
  • Looking for a self-hosted Google photos alternative with tags
    Hey Data Curators, I need your advice! I've been using Google Photos to 'organise' my picture library for the past few years, but now I'd like to replace it. For many obvious reasons. What I need is something that I can host myself (like piwigo or lychee), with decent mobile support and reliable auto upload from android. As well as that I really fancy some kind of tag-based file management system on top of that,... Source: about 5 years ago
