Grammarly vs Heptabase

Which should you choose?

These tools solve different problems and shouldn't be compared directly. Grammarly is a writing quality layer that works *within* your existing writing platforms—email, docs, social media. Heptabase is a knowledge management system for organizing research and ideas visually. Pick Grammarly if you write frequently and need real-time corrections across many apps; its tone detection and plagiarism checker justify the $12/month for professionals. Pick Heptabase if you're a student or researcher building a personal knowledge base and thinking spatially—its PDF annotation and video note-taking are rare, but the 7-day trial wall and no Android app limit accessibility. They're complementary, not competitive.
