Pick Synthesia if…
you make training, onboarding or explainer videos for an organization and want a presenter without booking a studio.
Synthesia and Captions are built for different buyers. Synthesia turns a script into a presenter-led video for corporate training and comms, sold by minutes of video. Captions is a short-form editor for solo creators, with auto-captions and a Digital Twin of yourself. They only meet on avatar-led talking-head video.
Pick Synthesia ($19/mo) for training and explainer videos with stock or personal avatars, AI dubbing and, on Pro, an API and interactive videos. Pick Captions ($24.99/mo) if you're a creator who wants an avatar of yourself plus captioning and editing for social clips.

Its free Basic plan gives 10 minutes of avatar video a month with 9 avatars, but you can't download videos. Downloads and branding removal start on Starter ($19/mo).
Synthesia Starter ($19/mo) is slightly cheaper than Captions Max ($24.99/mo), but Starter's monthly allowance of video minutes is small. Pro ($89/mo) raises it to about 60 minutes and adds 5 personal avatars and API access.
Synthesia lists API access on Pro. Captions also offers a developer API, but it's billed separately by usage rather than included in its app plans.
How we choose: prices come from each vendor's official pricing page and are re-checked every week. We take no affiliate fees, so rankings aren't for sale.
