product Knowledge Base
The brain your agents share.
Slack, Notion, Confluence, Drive — connected once, synced forever. Definable turns everything your team knows into a private second brain that grounds every chat, agent and workflow.

The knowledge engine · parse → chunk → embed → link
No tagging. No folders. No upkeep.
Connect a source and walk away. The engine parses every format — PDFs, decks, transcripts, screenshots — splits it into addressable chunks, embeds meaning and links the people, projects and decisions inside. A living index that updates itself as your tools change.

Semantic retrieval · cited by default
Answers with receipts.
Ask in your own words — retrieval works by meaning, not keywords. Every claim in every answer links back to the exact message, page or slide it came from. And when the brain doesn’t know, it says so.

Attach to chat · agents · workflows
One brain. Every surface.
Not another place to search — a layer under everything. Attach a brain to a chat, hand it to an agent, wire it into a workflow step. Same knowledge, everywhere work happens, so you never explain context twice.
Conversations that skip the backstory
Pin a brain to any chat and the Assistant answers from your sources first — no pasting context, no catching it up. It already knows.
- Answers grounded in your sources
- Citations on every claim
- Falls back honestly when the brain is silent
Agents that work in your voice
The Writer drafts from your brand brain. The Researcher cites your archive before the public web. Every agent shares the same memory.
- Brand voice from your own docs
- Internal knowledge outranks the open web
- One brain shared by the whole workforce

Runs that start informed
Any workflow step can read from the brain — and write back to it. Every run leaves the next one smarter.
- Steps query the brain mid-run
- Outputs write back as new knowledge
- Each run compounds the index

The platform underneath
Private. Permissioned. Never stale.
Live sync
Webhooks where possible, schedules everywhere else. Sources re-index on change — the brain is never stale.
Permission-aware
Source ACLs travel with the data. An answer never surfaces a doc the asker couldn’t open themselves.
Private by design
Tenant-isolated, encrypted at rest, hosted in your region. Your knowledge never trains anyone’s models.
Compounds daily
Every synced thread and shipped doc sharpens the next answer. A brain that gets better the more you use it.
