Synthesia review

Turn a script into a presenter-led video with AI avatars in dozens of languages

Pricing modelfreemium
Free tierYes
Best forHR professionals and trainers producing onboarding and compliance content that changes every year
Last reviewedSeptember 2026

Synthesia turns a written script into a video of a presenter reading it. You choose an avatar (stock or a version of yourself), pick a voice and language, add slides, screen recordings, and text, and the video renders in minutes. No camera, no studio, no re-shoots when the policy changes; edit the script and render again.

It is built for corporate video: onboarding, compliance training, product updates, sales enablement, and internal announcements. Templates, brand kits, collaboration, comments, and export to SCORM for learning systems reflect that. One-click translation produces the same video in other languages with the avatar's lip movement matched to the new audio.

The avatars are good and still recognizably synthetic on close viewing, which is fine for a compliance module and wrong for a brand anthem. The right way to think about it is as a replacement for the awkward, out-of-date recorded training video, and for the slide deck that should have been a two-minute explainer.

Best for

  • HR professionals and trainers producing onboarding and compliance content that changes every year
  • Customer service and operations managers explaining new processes and product changes to distributed teams
  • Marketers and sales teams who need multilingual product explainers without hiring presenters
  • Teachers and instructional designers building microlearning modules for an LMS
  • Companies that want consistent, on-brand video from many contributors who are not on-camera people

Not ideal for

  • Emotional brand storytelling or anything where a real human presence is the point
  • Cinematic content; use Runway or a production team for that
  • Very tight budgets with lots of video minutes; per-minute limits on lower plans add up

Key features

AI avatars, including your ownPick from a large library of stock avatars with varied ages and looks, or create a personal avatar from a short webcam or studio recording after consent verification. Expressive avatars react to the tone of the script.
Script-to-video in many languagesType or paste the script, choose the voice and language, and render. Tell it how to pronounce product names, and add pauses with punctuation.
One-click translationTranslate a finished video into other languages with the avatar's speech and lip movement matched. Have a native speaker review anything customer-facing; the translation is good, not perfect.
Templates, brand kit, and collaborationStart from templates for training, updates, and explainers, apply your fonts and colors, and let colleagues comment and edit in a shared workspace.
Screen recording, slides, and LMS exportCombine avatar scenes with screen recordings and imported slides, add captions, and export as video or SCORM for your learning management system. Check the vendor's current documentation for interactive features on your plan.

Pricing

A free plan with a few minutes of video per month and a limited avatar selection; paid individual and small-team plans (starter and creator levels) that raise the monthly minutes and add more avatars, custom backgrounds, and better collaboration; and enterprise plans with pooled or unlimited minutes, personal avatars for the team, SCORM export, single sign-on, and priority support. Pricing changes often; check the vendor's current plan page.

Minutes of rendered video are the unit that matters. Check whether re-renders consume minutes on your plan, and proofread the script before you render a long video.

Pros and cons

Pros

  • Fastest way to produce a presentable training or announcement video from a script
  • Updates cost minutes, not a re-shoot; change three words and render again
  • Broad language coverage with matched lip movement makes multilingual rollouts practical
  • Enterprise features (SCORM, SSO, brand controls, collaboration) fit how learning and communications teams actually work

Cons

  • Avatars remain slightly uncanny, and gestures and expressions are limited
  • Minute limits on lower plans constrain teams that produce a lot of video
  • Strict content moderation can block legitimate but sensitive topics; check the policy before planning content
  • Viewer fatigue is real: a library of identical avatar videos gets skipped

How people use Synthesia at work

HR professionals: keep compliance training current

Build the annual training as a set of short scenes, one per policy point. When a policy changes, edit that scene's script and re-render. Keep a human-hosted intro so the course does not feel fully automated.

Customer service reps: explain a process change to the whole team

Write a ninety-second script with the old way, the new way, and where to find help. Add a screen recording of the new tool. Send the link with a two-question quiz to confirm it landed.

Marketers: localize a product explainer

Produce the English version with a stock avatar, translate it into your top markets, and have a native-speaking colleague or contractor review each. Swap in localized screenshots where the interface differs.

Teachers: build microlearning for an LMS

Split a topic into three-minute modules, each with an avatar explanation, a slide, and a check question. Export as SCORM so completion tracks in your LMS, and cite sources in the notes for anything factual.

Getting started

  1. Sign up at synthesia.io, pick a template such as a product update, and paste a real ninety-second script from a recent announcement.
  2. Choose an avatar and voice, add pronunciation hints for product names, and render. Watch it with the sound off and on; awkward phrasing is much more obvious when spoken.
  3. Translate the video into one other language and send it to a native speaker for a sanity check.
  4. Before rolling out, read the content policy and the personal avatar consent process, and decide who in your company is allowed to create avatars.

Alternatives to Synthesia

Frequently asked questions

Is Synthesia free?
There is a free plan with a few minutes of video per month, enough to test the workflow. Ongoing use needs a paid plan sized by monthly minutes, and features like personal avatars for a team, SCORM export, and SSO are enterprise-level. Pricing changes often; check the vendor's current plan page.
Can I make an avatar of myself?
Yes. Personal avatars are created from a webcam or studio recording with consent verification, and availability depends on your plan. The result is a presenter who looks and sounds like you and can read any script, which is convenient and also a reason to control who can use it.
Do people mind watching avatar videos?
For instructions, updates, and training, most viewers accept them, especially when they are short and clearly labeled. For persuasive or emotional content, a real person still works better. Keep avatar videos under three minutes and mix in real footage where it counts.
Is Synthesia secure enough for internal company content?
It offers enterprise security controls and content moderation, and it verifies consent for personal avatars. Review its current security documentation with your IT team, and avoid putting confidential details in scripts unless your organization has approved the tool.
