Heptabase

For researchers, writers, and visual thinkers, absolutely. Heptabase solves a real problem, seeing relationships between notes in 2D space, that no other app addresses as well. PhD students, academics, and book writers consistently describe it as the tool that unlocked their research or writing project. For linear note-takers who just want bullet lists or folders, it may feel like overkill. Try the 7-day free trial first.

Miro and Whimsical are whiteboard tools designed for team diagramming, workshops, and flowcharts. Heptabase is a note-taking tool that uses whiteboards as a visual layer on top of a real note database. In Heptabase each card is a full note with markdown, backlinks, and search. In Miro or Whimsical, sticky notes are lightweight text blocks. If you need to do research and thinking, Heptabase. If you need to do team diagramming, Miro or Whimsical.

For visual research workflows, yes. For bulk plain-markdown note-taking and local-first ownership, no. Obsidian stores files as markdown on your disk and has a huge plugin ecosystem. Heptabase is cloud-based with a proprietary format and focuses on the visual experience. Many users actually use both: Obsidian for daily notes and a personal knowledge graph, Heptabase for specific research or writing projects where spatial thinking helps.

Yes. Heptabase's desktop and mobile apps work offline, you can create, edit, and view cards and whiteboards without an internet connection. Data syncs when you come back online. This is better than many cloud-first note apps, and critical for users who want to work from airplanes, cafes, or anywhere with unreliable WiFi.

Yes, as of 2025 Heptabase includes AI chat with your notes (ask questions across your entire card database and get cited answers) and automatic AI tagging that suggests tags for cards based on their content. It's not as deeply integrated as Notion AI or Capacities AI but it covers the two most useful use cases for a visual notes app.

No. Heptabase retired the lifetime license in its December 2025 pricing restructure. It now offers three subscription tiers: Pro at $11.99/month ($8.99/mo annual), Premium at $23.99/month ($17.99/mo annual) with unlimited PDF uploads and premium AI models, and Premium+ at $71.99/month ($53.99/mo annual) with the largest AI credit allowance. Early-bird Pro subscribers were grandfathered at $9.99/month or $83.88/year. If you are new to the app, start with the 7-day free trial on any tier.

Very different tools. Tana is an outliner with AI, supertags, and structured databases, great for systems thinkers. Heptabase is a visual whiteboard tool with cards in 2D space, great for visual thinkers. If you love outlines and structure, Tana. If you love seeing ideas laid out spatially, Heptabase. Some users describe Heptabase as "thinking in a whiteboard" and Tana as "thinking in a database," which captures the core difference well.
