I Ran Grammarly and Synthesia Side by Side for a Week

I had a deadline and two tools. One of them was going to waste my Saturday.

I put Grammarly and Synthesia through the same writing tasks last month instead of reading another ranked list.

Grammarly catches the typo you would have shipped to a client. Synthesia looks uncanny the moment you stare at the face - that gap showed up the moment I exported the file.

Where they overlap, Grammarly catches the typo you would have shipped to a client. Synthesia makes a talking-head video with an avatar that doesn't yawn. I kept both installed for a reason.

Synthesia makes a talking-head video with an avatar that doesn't yawn. Grammarly treats every sentence like it needs a confidence coach. Neither is broken; they argue about different things.

If you non-native writers and fast emailers, keep Grammarly. If you companies mass-producing training videos, Synthesia is the one. I landed on Grammarly for depth, Synthesia for speed after a week of switching back and forth.

Shipped the work, got paid, moved on. That's the review that matters.
