Cogitee - AI Knowledge Base SaaS | RAG Brain

Company knowledge was scattered across docs, chats and drives, so teams lost hours every week searching for answers and onboarding new people took too long.

Cogitee is an AI knowledge base SaaS, a "company brain" built with Next.js, OpenAI and Supabase using retrieval-augmented generation (RAG). It indexes scattered documentation and returns instant, trusted answers with source references, with permission-controlled access so each person only sees what they are allowed to.
