Collabmem – a memory system for long-term collaboration with AI
Hello HN! I built collabmem, a simple memory system for long-term collaboration between humans and AI assistants. And it's easy to install, just ask Claude Code: Install the long-term collaboration memory system by cloning https://github.com/visionscaper/collabmem to a temporary location and following the instructions in it. To collaborate with AI over weeks, months, or even years, there needs to be a shared conceptual understanding of: - History (episodic memory): what has been done, why, and what was decided and learned along the way. - Reality (world model): what the…
Collabmem – a memory system for long-term collaboration with AI launched on April 11, 2026 with 11 votes, #1,205 of 21,248 launches that month and more than 90% of that year's launches.
In plain words
Collabmem is a memory system that enables long-term collaboration between humans and AI assistants by maintaining shared episodic memory and world models across extended projects. It stores the history of work completed, decisions made, and lessons learned, along with project context, current status, and guidelines. The system is designed for users who want to sustain productive AI partnerships over weeks, months, or years by giving AI assistants persistent understanding of their project's background and constraints.

I replaced vector databases with Git for AI memory (PoC)2025 · github.com · ▲198Hey HN! I built a proof-of-concept for AI memory using Git instead of vector databases. The insight: Git already solved versioned document management. Why are we building complex vector stores when we could just use markdown files with Git's built-in diff/blame/history? How it works: Memories stored as markdown files in a Git repo Each conversation = one commit git diff shows how understanding evolves over time BM25 for search (no embeddings needed) LLMs generate search queries from conversation context Example: Ask "how has my project evolved?" and it uses git diff to show actual…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
