The honest comparison
When you bill by the hour, the tool that saves twenty minutes wins, full stop.
I put Synthesia and Leonardo AI through the same video tasks last month instead of reading another ranked list.
Synthesia makes a talking-head video with an avatar that doesn't yawn. Leonardo AI is less painterly than Midjourney when you want art - that gap showed up the moment I hit the paywall.
Where they overlap, Synthesia makes a talking-head video with an avatar that doesn't yawn. Leonardo AI gives game-ready assets with consistent characters across frames. I kept both installed for a reason.
Leonardo AI gives game-ready assets with consistent characters across frames. Synthesia looks uncanny the moment you stare at the face. Neither is broken; they argue about different things.
If you companies mass-producing training videos, keep Synthesia. If you indie devs and asset grinders, Leonardo AI is the one. I landed on Leonardo AI after a week of switching back and forth.
The avatar lip-sync is scary good in short clips. The API lets you batch a hundred icons overnight.
The one that saved me time is the one still installed.
