Heptabase vs Synthesia

Which should you choose?

These tools serve entirely different purposes and shouldn't be compared directly. Heptabase is a personal knowledge management system for researchers and students who think visually; Synthesia is an enterprise video creation platform. If you're choosing between them, you're solving different problems. Pick Heptabase if you need to organize complex research or learning material spatially. Pick Synthesia if you need to produce training or marketing videos at scale without hiring production crews. They don't overlap—one manages ideas, the other produces media.
