Heptabase
Verified working Jul 31, 2026
A visual note system for turning research sources into connected knowledge.
Heptabase is a knowledge-base app built around whiteboards, cards, linked notes, and source material. It combines research-oriented features such as PDF annotation, Zotero and Readwise integrations, daily journals, and an AI tutor that can help structure learning sessions around your materials.
Why it stands out
- Combines spatial whiteboards with linked-note knowledge management rather than treating notes as only pages or folders.
- Strong fit for academic workflows through PDF annotation, Zotero, Readwise, and source organization features.
- AI tutor is framed around structured learning sessions, not just one-off chat or summarization.
- Supports both capture and synthesis: web clips, highlights, journals, notes, discussions, and visual maps can live together.
Good to know
- The homepage emphasizes a 7-day trial, so long-term use appears to require a paid subscription.
- Its card-and-whiteboard model may require more intentional organization than simpler document-based note apps.
- The product is aimed mainly at learning and research workflows, not general team project management.
Under the radar: If you already use Zotero or Readwise, connect those early so your imported references and highlights become part of the same visual map instead of rebuilding your research library manually.
