Cabinet, a Knowledge Base + LLM system.

Technical Positioning

An open-source, local-first knowledge base for LLMs, integrating various data types (CSVs, PDFs, inline web apps) and supporting "bring your own agent" with heartbeats and jobs, positioned as "Paperclip+Obsidian" for LLMs.

SaaS Insight & Market Implications

Cabinet addresses a fundamental limitation of LLMs: their lack of dynamic, context-specific knowledge. By integrating a local-first, open-source knowledge base capable of ingesting diverse data types (CSVs, PDFs, inline web apps), Cabinet provides LLMs with a critical external memory. The "bring your own agent" model with heartbeats and jobs offers flexibility and control, empowering developers to customize AI behavior. This product taps into the growing trend of augmenting LLMs with structured data and agentic capabilities, moving beyond static training data. Its local execution and open-source nature appeal to privacy-conscious enterprises and developers seeking full control over their AI infrastructure, positioning it as a foundational component for advanced enterprise AI applications.

Show HN: Cabinet – Kb+LLM (Like Paperclip+Obsidian)

Hi HN,for quite some time I've been thinking how LLMs are missing the knowledge base, where I can dump CSVs, PDFs, and most important, inline web app. running on Claude Code (bring your own agent) with agents with heartbeats and jobsruncabinet.comIt runs locally and is installable via npm.
GitHub (open source): github.com/hilash/cabinetThi... is still very early. I put the first version together quickly after seeing a post by Andrej Karpathy about LLM knowledge bases, which matched closely with what I’d been building.
Some people have already started trying it and opening PRs, which has been encouraging (got 374 stars in 2 days :] )If useful:
Waitlist for a hosted version: runcabinet.com/waitlist
Discord (small, but growing): discord.gg/rxd8BYnNWould really appreciate feedback:
does this “KB + agents” model make sense?
what would you expect from a system like this?
where does this fall apart?
Happy to answer anything.Hila

really like the shipping of html apps inside knowledge bases, i can see a lot of very niche and useful internal tools being built to support a lot of custom workflows without leaving your actual knowledge base

I love this idea! I agree that LLMs often don't have the knowledge that's actually important (a frustration I have with ChatGPT is that it remembers unimportant things and then over-indexes on them in its responses).
