Why use AI avatars?
AI avatar videos are proven to drive results, cost less to produce, and scale to any language.
A UCL research report studying 500 adult learners found no significant difference in engagement or retention between an AI avatar video and human instructor video. Viewers completed the AI version around 20% faster.
An independent peer-reviewed study at USC Marshall tested AI avatar videos against human presenters across 250+ professionals and found identical knowledge transfer across both groups.
With AI avatars, the same video publishes across 160+ languages without a new recording. In our 2026 AI in L&D Report, 54% of respondents said global localization is where they expect AI to deliver the most value.

FAQs about AI avatars
What is an AI avatar?
An AI avatar is a digital presenter, generated by artificial intelligence, that speaks your script and acts out scenes you prompt, without a camera, studio, or filming session. Avatars can be photorealistic people or fully stylized characters, and each one performs with natural lip-sync and expression in any of 160+ languages.
Can I create an AI avatar video for free?
Yes. Synthesia's free plan gives you access to stock and customizable avatars, Avatar Builder, the core editor, and video generation in 160+ languages, with no credit card required. You can start from 240+ ready-made avatars, build your own avatar or character from a prompt, and prompt custom outfits, scenes, and on-screen actions generated with Veo 3.
Which is the best AI avatar generator?
Synthesia is the best AI avatar generator according to G2. The platform is trusted by 90% of Fortune 100 companies and 1M+ users, with over 20M avatar videos generated.
Compared to other AI avatar generators, Synthesia combines the most advanced avatar technology with an interface anyone can use from day one, enterprise-grade security, and a free plan to get started without a credit card.
Can I create cartoon, stylized, or character avatars?
Yes. Avatar Builder covers the full range, from photorealistic people to fully stylized and illustrated characters.
You can start from the Starter Library of ready-made looks, which spans styles like line art, editorial portraits, anime, 3D clay, and cartoon characters and creatures, or create your own by describing the character in a prompt or uploading a reference image to match a specific look.
Once it is generated, you name it and pair it with a voice from the 1,000+ library, then reuse the same character across your videos in any of 160+ languages.
Standard content moderation applies to everything you create, including stylised characters.
Can I customize AI avatars with my own branding, outfits, and style?
Yes, extensively. With customizable avatars, you prompt the outfit, setting, and on-screen actions in natural language and Veo 3 generates the scene. That includes industry-specific clothing like uniforms, hard hats, safety glasses, or lanyards, as well as branded outfits featuring your company colors and logo.
Apply your Brand Kit to layer logos, colors, and other assets across every video automatically.
Are AI avatars safe to use?
Yes, with multiple layers of protection built in. Every video goes through content moderation before delivery. Personal avatars require a live on-camera consent verification that cannot be uploaded or bypassed: the person shown in the consent video must match the person in the avatar footage, and they must be at least 18 years of age.
Synthesia is SOC 2 Type II, ISO 27001, ISO 42001, and GDPR compliant, with a dedicated Trust and Safety team. The platform is also a member of the Content Authenticity Initiative, and avatar owners can request deletion of their data at any time.
Can I make these AI avatars say anything?
Synthesia's AI video generator is used for business purposes with strict content moderation. We ask all our users to keep scripts professional and business related. Political, sexual, personal, criminal and discriminatory content won't be allowed.
Can I create an AI avatar of a colleague or team member?
Yes, through Synthesia's Personal Avatar Request feature, available on Enterprise plans. You send the person a unique link by email, they complete the recording and live consent verification themselves, and the avatar is created on your account. The person does not need their own Synthesia account to complete the process.
The consent video must always be recorded live. You cannot upload a pre-recorded consent clip on someone else's behalf, and the person shown in the consent video must be the same individual as in the avatar footage. Once created, avatars and voices can be shared across your workspace on Enterprise plans.
What voices do the AI avatars have?
Synthesia includes 1,000+ AI voices across 160+ languages and accents, available across our avatar library. Some voices include multiple emotional styles, so you can match tone to content, whether that is a calm instructional delivery or a more energetic announcement. Specific avatars including Ellie, Michael, and Zola offer multiple voice styles, paired with script-synced body language. If you create a Personal Avatar, you can also record a voice sample to clone your own voice.
Do I need video editing experience to create AI avatar videos?
No. Synthesia is designed for people who have never made an avatar video before. You can start from a document, a prompt, a PowerPoint, or a blank canvas, and the AI generates the script, picks the scenes, and produces a finished avatar video with lip-sync and voice included.
If you want to go further, the editor lets you add animations, images, music, captions, motion graphics, interactivity, and more, but none of that requires technical skills. Most users create their first AI avatar video within minutes of signing up.
