The challenge
Company knowledge was buried in wikis and threads — every document written started from a blank page and stale information.
What we built
An assistant with retrieval-augmented search across private docs: grounded answers with citations, drafts in the company's voice, and admin controls IT actually approved.
The outcome
Adopted by 12,000+ teams. Drafting time fell by half in customer studies, and 'source cited' became the feature users trusted most.
