About
Heptabase is a powerful, visual knowledge base designed to help individuals deeply understand and retain complex information. Built for students, researchers, and lifelong learners, it provides a unique whiteboard-first approach to note-taking that lets users spatially organize ideas, connect concepts, and visualize knowledge in meaningful ways. At the heart of Heptabase is an AI research assistant that can explain sources, summarize PDFs and YouTube videos, and conduct research with trustworthy citations — making it far more than a conventional note-taking app. The platform supports block-based editing, bi-directional links for connecting ideas across notes, PDF annotation, daily journals, and a web clipper for saving content from the web. Heptabase integrates with Readwise and Zotero, allowing users to bring in highlights, academic papers, and references seamlessly. Its blazing-fast search handles over 10,000 notes in under a second, and full offline access ensures productivity without an internet connection. Real-time collaboration lets users invite teammates or friends to work together at no extra cost. Available on Mac (including Apple Silicon), Windows, Linux, iOS, and Android, Heptabase is a fully cross-platform tool that supports mobile capture with voice notes. It is ideal for academic research, deep study sessions, writing projects, and building a long-term personal knowledge management system. With its visual-first design and AI capabilities, Heptabase stands out as a PKM tool built around how people actually think and learn.
