About Heptabase

Heptabase is an intelligent, visual knowledge base built for researchers, students, and lifelong learners.

Unlike traditional linear note-taking apps, Heptabase empowers you to visually organize your thinking. You can capture ideas as atomic "cards" and arrange them on flexible whiteboards to see the big picture. Whether you are analyzing PDFs, managing projects, or synthesizing research, Heptabase helps you bridge the gap between gathering information and truly understanding it.

Key Features:
  • Visual Whiteboards: Map out complex ideas and structure your research spatially.
  • Universal Cards: Reuse the same note across multiple projects without duplication.
  • Seamless Capture: Integrated PDF annotation, Readwise sync, and web clipping.
  • AI Assistance: Use AI to summarize sources and find connections in your knowledge base.
  • Offline First: Blazing fast performance with full offline access.

Note:

AI features will not work unless you supply your own API key.
