Heptabase
Visual note-taking on a card-and-whiteboard canvas
Overview
Heptabase is a card-based PKM tool with whiteboards — write atomic notes on cards, then visually arrange them on canvases to develop ideas. AI features include semantic search and chat across cards. Subscription only.
Use cases
What you can produce with Heptabase
- Break a research topic into atomic note cards and arrange them on an infinite whiteboard to map how the ideas connect.
- Annotate PDFs of papers or books and pull the highlights out as cards you can reuse across whiteboards.
- Ask the AI assistant questions across your entire note library and get answers with citations back to your own cards.
- Link related cards bi-directionally so you can trace an idea through every context where you used it.
- Keep a daily journal that connects to your project notes instead of living in a separate app.
- Work fully offline on desktop or mobile and let changes sync automatically when you reconnect.
- Draft a long-form piece — thesis chapter, essay, report — by composing directly from the cards you arranged on a whiteboard.

Heptabase is a visual knowledge-management tool that pairs an infinite whiteboard with structured notes, cards, and PDFs, designed for deep learning, research, and making sense of complex topics. Its standout is the spatial canvas for connecting ideas, and newer AI features help summarise and surface notes. It suits researchers, students, and knowledge workers who think visually and want more structure than a plain note app.
Caveats: it is subscription-only with no free tier beyond a trial, the visual-first approach is a learning curve and overkill for simple notes, and it is less suited to team collaboration than personal thinking. Mobile is improving but desktop-centric. English-first, globally usable; no ASEAN-specific features. No meaningful public API.
What people say
Heptabase is still independent and actively developed, retaining its subscription-only model: no free tier beyond a 7-day trial, with yearly pricing around $8.99 a month, a pricier tier for unlimited PDF and full AI access, and a lifetime option. Development pace is a recurring theme in reviews — users note a steady stream of updates and a team that visibly listens to its community. Recent releases added AI chat across your cards with cited answers, AI tag suggestions, and research assistance drawing on OpenAI, Google and Anthropic models, alongside long-requested basics like offline support and mobile sync.
The consistent praise centers on the core idea: writing atomic notes on cards and arranging them spatially on whiteboards genuinely helps some people think. Reviewers coming from Obsidian or Notion describe finally seeing the structure of a research topic, thesis or book project. The app is frequently called fast and minimal, PDF annotation is well liked for academic reading, and bi-directional links plus a journal round out a serious PKM feature set with far less setup than plugin-heavy rivals.
Criticisms are equally consistent. Users report lag and buggy behavior on large whiteboards or under heavy PDF loads, weak task and to-do handling that stops it replacing a project manager, and UI rough edges. The subscription-only model draws grumbling in a category where Obsidian is free, and AI credits are metered on the standard plan. Several reviewers conclude it is a brilliant thinking tool but not yet ready to be their only tool.
Heptabase fits researchers, students and writers doing sustained deep work on complex topics — people who will actually spatially arrange their notes rather than just file them. If your need is quick capture, team collaboration or task management, or you are unwilling to pay a subscription for notes, the honest recommendation from its own user base is to look elsewhere.
