Everyone's building a company brain. Almost nobody understands what that actually means.
Karpathy's personal LLM knowledge base went viral. Garry Tan built GBrain. YC people are clearly paying attention to the category.
But here's what most of these get wrong:
A personal brain is small, fast, and permission-less. A company brain serves hundreds of people, enforces access controls, and has to heal itself when it goes wrong.
Most tools are just personal brains scaled up. They break at the seams.
Slite's thesis is different:
→ Company knowledge needs a verification layer
→ It needs to be legible to both humans and agents simultaneously
→ It needs to self-correct, not just store
After 10 years building knowledge bases and 2 years on AI search, they just shipped the first 𝐬𝐞𝐥𝐟-𝐦𝐚𝐢𝐧𝐭𝐚𝐢𝐧𝐢𝐧𝐠 𝐤𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞 𝐛𝐚𝐬𝐞.
The Slite Agent monitors 20+ connected tools, detects drift, proposes fixes, and queues them for human review. Claude, ChatGPT, Cursor - any MCP-compatible agent, can read and write to it directly.
Accurate context at the company level is a different problem than accurate context at the personal level.
Someone finally built for the right problem.
The interesting part isn't that Slite added AI to docs.
It's that they're treating company knowledge like infrastructure

Every named product and core claim checks out against real, current sources:

GBrain is real, built by Garry Tan. GBrain is an open-source AI memory system created by Garry Tan, CEO of Y Combinator — a markdown knowledge base backed by Postgres that ingests meetings, emails, and messages, stores them as pages, and maintains a typed knowledge graph. He open-sourced it in April 2026, days after AI researcher Andrej Karpathy seeded the idea publicly, confirming both the Karpathy and Garry Tan claims in your post. Slite Slite
Slite's self-maintaining knowledge base is real and matches the "verification layer" framing precisely. Slite is the first self-maintaining knowledge base: a structured, verified wiki paired with an AI agent that keeps documentation in sync with reality — Slite Agent detects when docs have drifted, proposes the fix, and routes every change through human approval before anything is applied. Slite
20+ connected tools, MCP compatibility confirmed. Slite connects 20+ tools and is reachable from Slack, a Chrome extension, and the web app, and via MCP, so AI agents like Claude can read and propose changes. Slite pairs a verified knowledge base with an AI agent connected to all team's tools, detecting when docs get outdated and keeping them in sync with reality. Slite Y Combinator
"Any MCP-compatible agent can read/write directly" — confirmed. The same engine that powers the Agent is exposed via MCP — your verified knowledge becomes the source of truth for Claude, ChatGPT, Cursor, and anything else your team plugs in. Slite

One nuance worth flagging on the "personal vs. company brain" contrast:

Your post frames GBrain as purely a "personal brain scaled up" that "breaks at the seams" — this is somewhat one-sided marketing framing (understandably, since it's effectively promoting Slite). In reality, GBrain has added team functionality where each person gets their own slice of the brain scoped by login, with fuzz-tested access controls and zero data leaks across search/list/lookup reads, so GBrain isn't purely single-user anymore — it has some multi-user permissioning, even if Slite's enterprise-grade compliance (SOC 2, HIPAA, GDPR) is more mature.

Fake content: 0%. All named products, founders, and core mechanics are accurate — the framing is competitive marketing copy (favoring Slite over GBrain), not factual misrepresentation.
