What it does
Heptabase is a visual knowledge workspace that combines note cards, whiteboards, daily journals, PDF highlights, web clipping, and bidirectional links. Its official site describes using cards and whiteboards to organize sources and ideas, and its changelog documents frequent product improvements through October 2026. Pro is listed at $8.99 per month, with higher tiers for additional AI and PDF features.
Lay out research notes and connect related ideas
Heptabase is built around cards placed on visual whiteboards, with links that connect notes and source material into a knowledge base. The official product page lists PDF annotation, YouTube transcripts, daily journals, web clipping, Readwise and Zotero integrations, and AI tools. The spatial layout can help a learner or researcher compare ideas across materials; it is more opinionated than a conventional folder of notes.
The pricing page lists Pro at $8.99 per month and Premium at $17.99 per month with added AI and PDF features. Its public changelog shows activity through October 22, 2026, including card, journal, mobile, and AI-agent improvements. I did not create a workspace, add a source, build a whiteboard, or test sync, PDF parsing, or AI features.
