Ehsan's Verdict

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