These two get shortlisted together and they should not be. They do not compete: Descript edits video you filmed, Synthesia generates video you never filmed. Comparing their feature lists produces nonsense, because the question is not which is better but whether you are going to be on camera.
So the deciding question is upstream of both products. Does the footage already exist?
Choose Descript if you record yourself or your calls and the slow part is cutting it down — it lets you edit video by editing the transcript. Choose Synthesia if nobody is going to film anything and you need repeatable training or explainer video, especially in several languages. If you are unsure, you almost certainly want Descript: editing footage you already have is a smaller commitment than building a video pipeline around an avatar.
What Descript is actually for
Descript turns a video into a transcript and lets you cut the video by deleting words. For talking-head content — consultant explainers, podcast clips, recorded calls turned into short-form — that is dramatically faster than a timeline, and it removes filler words in one pass. It suits consultants recording video, podcasters, and small agencies producing content regularly.
What Synthesia is actually for
Synthesia generates video from a script using an AI avatar, which means the output is repeatable and localisable in a way filmed footage is not. Its natural home is training content and sales explainers inside agencies and training teams, where the same material has to be produced again every time a process or a product changes.
The limitations each one carries
Descript is not a substitute for a proper editor on complex work: it is built for talking-head video, its per-seat pricing climbs quickly across a team, and heavy projects strain a modest machine. Synthesia's free tier is capped at roughly ten minutes of video a month, the base plan limits which avatars you can use, and it often expects an annual commitment. Neither is a good fit for the case the other owns.
Who should buy neither
If you need occasional short videos and nothing more, Synthesia is explicitly not built for you, and Descript's free plan will probably cover the work without a subscription. Both free tiers exist precisely so you can find that out before paying — start there and let the limit you hit first tell you which problem you actually have.
Where Loom fits between the two
Loom sits in a third position that neither of these occupies: it records you and shares the result as a link, with no editing step at all. If the job is explaining something to a client and the video is disposable, that is the cheaper answer — its free plan covers 25 videos and five-minute screen recordings. Descript earns its price when the recording has to be cut down and reused; Loom earns its place when the recording is the deliverable and speed matters more than polish.

Frequently asked questions
Can Descript replace a real video editor?
For talking-head video, often yes. For anything needing frame-accurate cuts, layered effects or complex sequencing, no — the tool is honest about that, and so are we. It is a transcript-first editor, which is a strength for interviews and explainers and a limitation everywhere else.
Does avatar video look obviously artificial?
Quality is high enough for internal training and product explainers, which is where it is mostly used. Whether that suits customer-facing brand video is an editorial judgment about your audience, not a technical one — and it is worth testing on the free tier before it becomes a commitment.
Could a small team use both?
Yes, and some do: Synthesia for material that must be reproduced in several languages, Descript for anything filmed. But that is two subscriptions for a small team, so it only makes sense once each one is solving a problem you can name.
