About Heptabase
Heptabase is a visual note-taking and knowledge management app built around a spatial canvas where you arrange cards, whiteboards, and mind maps to understand complex topics. Unlike linear note apps, Heptabase lets you place notes, PDFs, images, and highlights on an infinite canvas to see connections spatially. It excels at learning and research workflows — the Readlist feature captures highlights from PDFs and web articles, while the Journal view maintains a chronological record. Heptabase's AI can answer questions across your entire knowledge base, making it one of the most powerful tools for researchers, students, and knowledge workers building a 'second brain'.
