Knowbase

Knowbase is a cloud platform that converts a variety of file types (PDF, Word, PowerPoint, audio, video, and more) and connected sources (Google Drive, Notion, web domains, YouTube) into a searchable knowledge base backed by AI.

The product targets students, researchers, professionals, teams, creators, and executives who need fast, verifiable access to information inside their documents and recordings.

Core capabilities include building and deploying AI chat assistants from your documents, a Document Chat interface for asking questions with citations, AI transcription with automatic speaker diarization and subtitle export, and options to share files, collections (Nests), or embed an AI chatbot widget on websites.
