Ehsan's Verdict

Most teams agonize over Devin vs Grammarly for the wrong reasons. After advising 200+ startups, the real question is workflow fit. Devin dominates when your core loop requires code depth. Grammarly wins when you need writing embedded in daily operations. The 3x productivity difference comes from integration density, not feature checklists.
