Synthesia Review

Reviewed by Tom · Founder & lead reviewer

The problem it solves

Corporate video has always had a brutal cost structure: a camera, a presentable presenter, a quiet room, and a full reshoot every time the product changes. Synthesia deletes all of it. You type a script, pick an avatar and a voice, drop in slides or screen recordings, and get a finished talking-head video - and when the pricing page changes next quarter, you edit the text and re-render instead of rebooking a studio. For training libraries that go stale monthly, that single property changes the economics of keeping content current.

Living with it

The editor feels like building a slide deck that happens to talk: scenes on a timeline, script per scene, avatar in the corner or full frame. The avatars are genuinely good at neutral, instructional delivery - viewers stop noticing within a minute - but push into humor or empathy and the synthetic edge shows. The multilingual side is the quiet killer feature: one script becomes a dozen localized versions with matched voiceover, which used to be an agency invoice. Watch the minutes meter, though; a busy L&D calendar eats entry-tier allowances fast.

Should you buy it?

If your videos are instructional - onboarding, compliance, how-tos, product explainers - and you make them regularly, Synthesia pays for itself in the first month you skip a filming day, and the free tier is enough to prove it on your own script. If you produce video occasionally, the per-minute math is less kind. And if you are after ads, brand films, or anything meant to move people emotionally, this is the wrong aisle - Synthesia replaces the training studio, not the creative one.

Best for

L&D teams, HR departments, and product marketers who need presenter-style videos in many languages without cameras, studios, or reshoots.
