Overview

About Heptabase

Heptabase is a visual knowledge-base app for students, researchers and lifelong learners, built around card-based notes laid out on whiteboards with bi-directional links. It handles PDF highlights, YouTube transcripts, web clipping and a daily journal, connects to Readwise and Zotero, and ships a CLI meant for developers working with Claude Code or Codex. An AI agent explains sources, takes notes and helps organise the base, and the Premium tier adds an AI tutor that runs structured study sessions. It runs on Mac, Windows, Linux, iOS, Android and the web, with AI use metered in monthly credits and a 7-day trial before the first charge.

Editorial verdict

Pros & cons of Heptabase

high confidence

Heptabase treats the whiteboard, not the linear document, as the core unit of note-taking, which sets it apart from outline-first tools, and the AI layer is built on top of that spatial structure rather than bolted onto a chat sidebar. AI credits are metered even on the cheapest paid tier, so heavy AI use pushes users toward Premium quickly.
