MetaBrain, a local document memory for AI agents, with human collaboration features.

Technical Positioning
Addresses the need for AI agents to track contextual data beyond 1D chat and dynamically retrieve specific knowledge. Also allows human collaboration.
SaaS Insight & Market Implications
MetaBrain targets a critical emerging pain point in AI agent development: persistent, discoverable, and context-rich memory. Current agentic systems often struggle with maintaining long-term context and accessing relevant information beyond immediate chat history. This product provides a structured, local document store, enabling agents to dynamically retrieve and re-inject specific knowledge. The human collaboration aspect (reading/searching/editing) bridges the gap between human oversight and autonomous agent operation. Its cross-platform, open-source nature and focus on efficient data retrieval (search, compression) position it as a foundational component for robust, enterprise-grade AI agent deployments, addressing scalability and reliability concerns.

Show HN: MetaBrain – A local document memory for AI agents

Hello there HNI experimented with agentic coding recently and I felt the need to track more contextual data by project.
Also I felt the need to be able to go beyond the 1D chat to communicate with agents.So I created a local document memory, that is discoverable by agents themselves.
The CLI is designed to be easy to pick up by agents.
It allows humans to collaborate too by reading / searching / editing documents in the store.I have a Mac native GUI in the review process, I hope it will show up in the App Store soon.You can try it easily, instructions here: metabrain.eu
Here is the GitHub github.com/OpenCow42/metaBra... project is also an experiment for me to build some swift project truly cross platform (Mac / Linux / Windows)
It is open-sourced with the same license as LevelDB that I wrapped in swift to do this project.The agents (and humans) can retrieve content quickly with a search, allowing to re-injecting specific knowledge in a specific context during agentic work.
It’s funny, I’ve thought of "inference rule base" as something of a derelict idea of the old functional expert systems.
Now that I start working with agents I feel more and more the need to go pick previously working solutions dynamically in such a base.I’d be happy to get feedback.
Product fit wise, would this be useful to you or is this just me who is happy with it ?Finally I had fun with the compression of documents, it tries ZSTD quick, if it does not compress the data by more than 10 percent it stores data uncompressed, else it does a ZSTD level 9 compression on the data. I picked up this trick form OpenZFS.Thanks
