Grammarly vs Synthesia

Which should you choose?

These tools solve entirely different problems and shouldn't be compared directly. Grammarly refines existing written text through real-time suggestions and checks; Synthesia generates video content from scratch. Pick Grammarly if your workflow centers on writing—emails, documents, social posts—and you need grammar, tone, and plagiarism detection across 500+ apps. Pick Synthesia if you need to produce training videos, product demos, or multilingual marketing content without hiring actors or cameramen. Grammarly costs ~$12/month for premium; Synthesia targets teams with higher budgets. They're complementary, not competitive—use both if creating written content that later becomes video.
