Businesses create workspaces, upload documents, and ask questions that are answered strictly from their own content using RAG (vector search with citations). The platform supports multi-user workspaces, document organization, AI Q&A, analytics, and public or private knowledge portals. Subscriptions and usage limits are already implemented via Stripe, making it ready to monetize or scale immediately. The codebase is clean, modern, and fully owned, built with Next.js, TypeScript, PostgreSQL (pgvector), and an OpenAI-compatible AI layer that can be easily swapped or extended. This is a strong foundation for anyone looking to launch or grow an AI-powered SaaS in the knowledge management, internal tools, or productivity space without starting from scratch.
