Show HN: Yet another memory system for LLMs

60 blackmanta 14 8/14/2025, 3:34:11 AM github.com ↗

Built this for my LLM workflows - needed searchable, persistent memory that wouldn't blow up storage costs. I also wanted to use it locally for my research. It's a content-addressed storage system with block-level deduplication (saves 30-40% on typical codebases). I have integrated the CLI tool into most of my workflows in Zed, Claude Code, and Cursor, and I provide the prompt I'm currently using in the repo.

The project is in C++ and the build system is rough around the edges but is tested on macOS and Ubuntu 24.04.

How do you use this in your workflow? Please give some examples because it’s not clear to me what this is for.

>MCP server (requires Boost)

I see stuff like this, and I really have to wonder if people just write software with bloat for the sake of using a particular library.

SJC_Hacker · 26m ago

Blame the committee for refusing to include basic functionality like regular expressions , networking and threads as part of the STL

pessimizer · 45m ago

Boost is a nearly 30 year old open source library that provides stuff for C++ that most standard libraries for other languages already have out of the box. You seem to think that it is hipster bullshit rather than almost a dinosaur itself.

How would you use the built in functionality to enable graph functionality? Metadata or another document used as the link or collection of links?

I'm puzzled - where are the header files?

JSR_FDED · 1h ago

Thanks, I learned a lot from this.

marcofiocco · 2h ago

What about versioning of files?

blackmanta · 2h ago

The tool has built-in versioning. Each file gets a unique SHA-256 hash on storage (automatic versioning), you can update metadata to track version info, and use collections/snapshots to group versions together. I have been using the metadata to track progress and link code snippets.

Wicked cool. Useful for single users. Any plans to build support for multiple users? Would be useful for an LLM project that requires per user sandboxing.

The domain listed on the GitHub repo redirects too many times.

blackmanta · 3h ago

That should be fixed now. It was a misconfiguration of CloudFlare SSL with GitHub Pages.
