Key features
Capacities
- Object types
- Every note is a typed object, such as a person, book or project, with its own properties and templates. Objects can be shown as lists, galleries, tables or cards.
- Daily notes
- One note per day works as an inbox for quick thoughts. Content can also be sent in from WhatsApp, Telegram or by email.
- Links, backlinks and graph view
- Links between objects work in both directions. A backlinks panel lists every reference to an object, and a graph view draws the whole network.
- AI assistant (Pro)
- AI chat, property auto-fill and analysis of web links and images, limited by a monthly budget. The Plus add-on raises that budget.
- Smart queries, tasks and calendar (Pro)
- Pro adds saved queries, task management with actions for apps such as Todoist and Things, and calendar integration for Google, Microsoft, Apple and CalDAV.
- Offline mode and web extension
- Offline mode lets you open, create and edit content without a connection. A browser extension for Chrome, Edge, Safari and Firefox saves pages to a space.
Heptabase
- Whiteboards and cards
- Each note is a card, and cards are laid out on whiteboards to work through a topic visually.
- Block editor with bi-directional links
- Cards are written in a block-based editor with slash commands and can link to each other in both directions.
- PDF highlights and source Q&A
- Highlight PDFs in several colors and ask AI to explain PDFs, YouTube videos, notes and journal entries. Unlimited PDF uploads and OCR parsing need Premium.
- AI agent and AI Tutor
- An AI agent helps take notes and organize knowledge, drawing on monthly AI credits. AI Tutor, which runs structured learning sessions, is part of Premium.
- Daily journal
- A journal entry for each day sits alongside a calendar and to-dos.
- Offline access and collaboration
- Notes and files stay available without an internet connection, and friends or teammates can be invited to collaborate in real time for free.
