Direct answer

What is Heptabase?

Heptabase is a visual note-taking and knowledge base workspace combining infinite whiteboards, card notes, PDF annotations, and an AI tutor for learning.

Heptabase is an intelligent, visual workspace designed for deep research, study, and knowledge organization. It pairs an infinite whiteboard canvas with structured, block-based card notes and bi-directional linking, allowing users to map concepts spatially without losing atomic text structure. The platform integrates source handling directly into the workflow, supporting PDF annotation, optical character recognition (OCR), and YouTube transcript extraction alongside daily journals and a web clipper. Built-in integrations connect with external reference tools such as Readwise and Zotero, while the Heptabase CLI supports interaction with developer tools like Claude Code and Codex. Heptabase also includes conversational AI assistance and an AI Tutor feature. The AI Tutor plans structured, multi-part course syllabi and facilitates step-by-step interactive lessons directly within the app. The software runs across desktop and mobile operating systems with full offline access, real-time collaboration, and local indexing capable of searching over 10,000 notes in under a second.
