Synthesia turns written scripts into videos presented by AI avatars, removing the need for cameras, studios and presenters. It has grown from avatar video into a broader platform for corporate communication and learning, with dubbing, interactive elements, roleplay practice sessions and LMS export. This review looks at what Synthesia documents today, what its plans include and which organizations it suits best.
What it is
Synthesia is a browser-based video creation platform aimed mainly at businesses: learning and development teams, HR, sales enablement, customer education and internal communications. Users pick an avatar and voice, type or import a script, and Synthesia generates a presenter-led video that can be edited like a slide deck. Our Synthesia directory entry gives a short overview.
Key features
- AI avatars. A stock library that grows by plan (9 on Basic, 125+ on Starter, 180+ on Pro and 240+ on Enterprise). Synthesia describes “expressive” avatars that gesture and point based on the script.
- Personal avatars. Users can create an avatar of themselves by recording a short video, from home, the office or outdoors. Pro includes five; Enterprise is unlimited.
- AI Video Assistant. Turns a prompt, script, document, slide deck, PDF or web page into a draft video.
- AI Playground. Generates b-roll with third-party models, which Synthesia lists as including Veo 3.1, FLUX.2 and Nano Banana Pro.
- Voices and localization. AI voices in 140+ languages, AI dubbing that keeps the speaker’s voice with lip-sync, one-click translation into 140+ languages on Enterprise, and a multilingual player.
- Interactivity and analytics. Quizzes, calls to action, branching scenarios, video analytics, conversational surveys and avatar-led roleplay sessions.
- Distribution. Public video pages, embeds that update automatically when a video is edited, password or SSO access control, and SCORM export for learning management systems.
- Screen recorder. An AI screen recorder with automatic transcription and pause removal.
Pricing
At the time of writing (October 2026), Synthesia’s official pricing page lists (US dollars):
| Plan | Monthly billing | Annual billing | Highlights |
|---|---|---|---|
| Basic | $0 | $0 | 10 minutes of video, 9 avatars, 1 editor, watermark, share by link |
| Starter | $29/month | $18/month | Downloads, no Synthesia logo, AI Video Assistant, 125+ avatars, 1 editor and 3 guests |
| Pro | $89/month | $64/month | 5 personal avatars, interactive videos, branded pages, 180+ avatars, 1 editor and 5 guests |
| Enterprise | Custom | Custom | Unlimited video minutes, SSO, live collaboration, brand kits, SCORM export |
Usage on paid plans is measured in credits that convert to video minutes, dubbing minutes and survey responses. Synthesia’s page puts Starter at roughly 12 extra video minutes a month and Pro at roughly 60, but some of its figures for credits are stated inconsistently across the page, so buyers should confirm allowances before purchasing. Roleplay learner seats are an add-on at $29 per learner per month, or $25 on annual plans.
Strengths
Synthesia solves a real business problem. Training and internal communication videos are expensive to film and quickly go out of date. Generating them from a script, and updating every embedded copy by editing once, changes the economics of keeping training current.
Localization is a standout. Voices in more than 140 languages and dubbing with lip-sync let a global company produce one video and publish it in many languages, something that would otherwise require separate recordings.
Governance is taken seriously. Synthesia says every avatar is created with explicit consent and every video is moderated at the point of creation. It states it was the first generative AI company certified to ISO 42001, displays SOC 2 compliance, and says AI-generated content is labelled in line with Article 50 of the EU AI Act. Our EU AI Act explainer covers why those labelling rules matter.
Limitations
The lower tiers are tight. Around 12 extra minutes a month on Starter suits occasional explainers, not a full training curriculum, and the free plan’s watermark and lack of downloads make it a trial rather than a working tier.
Key team features sit at the top. Live collaboration, brand kits, SAML/SSO, SCORM export and one-click translation into all languages are listed for Enterprise, so organizations rolling out training at scale should expect a sales conversation and custom pricing.
Avatars are not a fit for every message. Presenter-led AI video works well for instructions and explainers but can feel impersonal for sensitive announcements or brand storytelling. Organizations should also be transparent with viewers that presenters are synthetic; our guide to deepfakes explains why disclosure matters.
Who it’s for
- Learning and development teams producing and updating training at scale.
- Global companies that need the same content in many languages.
- Sales and customer education teams creating product explainers and onboarding videos.
- HR and internal communications teams publishing policy and process updates.
Alternatives
- Descript — editing real recordings, with AI avatars and voices as add-ons.
- Runway — generative video for creative and cinematic work.
- ElevenLabs — voice generation and dubbing without avatars.
Verdict
Synthesia earns 4 out of 5. Its documented feature set is well matched to corporate training and communication, with strong localization, interactive learning tools and a credible approach to consent and moderation. We hold back a point because the Starter and Pro allowances are limited, several features that large teams need are reserved for custom-priced Enterprise, and the pricing page presents some allowances inconsistently.
