Heptabase vs Microsoft Copilot

Which should you choose?

These tools serve fundamentally different purposes and shouldn't be directly compared. Heptabase is a specialized knowledge management system for visual thinking and research organization; Microsoft Copilot is a general-purpose AI assistant for productivity tasks. Pick Heptabase if you're managing complex research, learning projects, or need spatial reasoning tools—its whiteboard system and native PDF/video annotation are genuinely differentiated. Pick Copilot if you need an AI writing and analysis partner integrated into Microsoft Office. They're complementary, not competitive: a researcher might use both, leveraging Heptabase for knowledge structure and Copilot for content generation within Word. The comparison itself is a category mismatch, but Heptabase has clearer product focus; Copilot tries to do everything and does nothing exceptionally well versus specialized tools.
