Synthesia

What it actually does

You type a script, pick one of the stock AI avatars, and Synthesia returns a video of that avatar reading your words to camera. There is no camera and no talent to book. The same script can come back in any of 120+ languages, which is the feature most buyers are actually paying for, and the platform also does voice cloning, custom avatars of your own people, and screen recording.

The honest description of the output is a talking head over a slide. That covers a lot of real work: onboarding, compliance refreshers, internal announcements, product walkthroughs. It does not cover anything that needs performance, and you should not expect it to.

What it costs

Starter is $22 a month, Creator is $89 a month, and Enterprise is quote-only. There is no free plan, so you cannot try it on a real script without paying first. The per-plan video allowance is the number people miss at checkout: Starter buys about five minutes of finished video a month and Creator about thirty. Thirty minutes is one short course.

Add seats to that and the math turns. Teams report that per-seat and per-minute limits punish exactly the workload the product is sold for, which is a training library that keeps growing. If you are budgeting, price the minutes you need per year, not the monthly headline.

Where it falls down

Price is the dominant complaint and it is not close. Users describe Synthesia as very expensive for what arrives, and the metering is the reason. Hard caps on individual video length are the second recurring gripe, because they force you to chop a twenty-minute module into awkward pieces that then need stitching and renaming.

The avatars remain the aesthetic problem. Reviewers describe them as stiff or uncanny for anything past explainer content, with limited gesture and emotion range, and realism that varies noticeably between languages. Instructional designers go further and report that the videos do not move the needle on learning outcomes, which makes the spend hard to defend internally when a PDF and a voice track would test the same.

The scores split along buyer size. G2 sits at 4.6 from 2,806 reviews, while Trustpilot sits at 3.9 from around 1,823. We read the G2 figure on the page and picked up the Trustpilot number from search metadata and two third-party writeups rather than the page itself, so treat it as slightly softer. That gap usually means one thing: enterprise accounts with support attention are happy, and individual subscribers paying retail are not.

One more thing worth knowing before you put your CEO's face in a model. Deepfake misuse is a live press theme for this whole category, and Synthesia's answer is content moderation policy rather than anything technical. We found no lawsuits, acquisitions or regulatory actions against the company in this pass.

Who should buy it

Corporate L&D and internal communications teams with a real budget and a multilingual audience. If you are shipping the same fifteen-minute module in eight languages, nothing else in this category gets you there for less, and support is repeatedly described as helpful and responsive, which is genuinely unusual here. The 4.0 score is for that buyer.

Do not buy it as an individual creator. At $89 a month for thirty minutes you are paying enterprise rates for a product whose cheap tiers strip the customization that makes output look like yours. YouTubers, course sellers on a single-language audience, and anyone who needs a face with warmth should record themselves; a decent microphone and a phone costs less than three months of Creator and reads better.

Also skip it if the goal is measurable learning gain rather than volume. Buy it to produce more video faster in more languages. That is the thing it does, and it is the only thing you should expect.
