Synthesia Review 2026: AI avatars for training videos you cannot justify filming

Synthesia makes sense for content you can't justify filming: evergreen course lessons, product walkthroughs, onboarding and multilingual explainers. For personality-led creator content, your audience will probably notice the avatar, and Synthesia's own rules keep stock avatars out of opinion pieces, sponsored content and paid ads.

What it does well

Presenter-led explainers. Write a script, pick an avatar, add slides or screen recordings, and Synthesia renders the presenter speaking it. Brand kits and templates keep a series of lessons looking consistent.

Localization. Self-serve plans dub uploaded videos or YouTube links into 70+ languages, with optional lip-sync. Synthesia estimates up to 16 extra minutes of dubbing a month on Starter and 78 on Pro.

An avatar of you. Personal avatars (3 on Starter, 5 on Pro) need a recorded consent video, and Synthesia says your avatar and cloned voice are exclusive to you. Voice cloning is on every plan, and the speaker reads a passcode aloud as consent.

Clear ownership. Synthesia's customer terms say you own your inputs and outputs, and paid plans export MP4s.

Where it falls short

• Stock avatars have tight content rules. Synthesia's help center limits stock avatars to neutral, educational content: no endorsements, opinions, real companies, current events, or medical, legal, financial, news or political topics. Its licensing page bars them from paid ads on YouTube, Instagram, TikTok and elsewhere. A sponsored review needs a personal avatar of you.
• Uncanny for some viewers. Synthesia's demos look strong, but avatars still read as avatars to part of any audience. Use them where clarity matters more than charisma.
• Your digital twin stays put. Avatars can't be exported. Leave and you keep your MP4s, not the avatar.
• Pricey for creators. Per finished minute, it costs more than filming yourself with a phone and an editor.
• Data use. Usage data improves the service, but the terms say that can't go beyond your instructions or an avatar subject's consent.

Pricing in practice

Synthesia changed its plans on Oct 1, 2026. Every plan now includes 10 minutes of video or dubbing, 3 survey responses and 500 credits each month, and paid plans add credits on top. A typical finished minute uses about 100 credits, per Synthesia's help center.

• Basic (free, $0): 9 avatars, watermark, share by link only (no MP4 download). Good for testing, not publishing.
• Starter ($19/mo billed monthly, or $14/mo billed annually, $168 a year): 1,750 credits a month in total (about 27 minutes of finished video by its help center's math; its pricing page estimates about 22), MP4 download, no watermark, 125+ avatars, 3 personal avatars.
• Pro ($89/mo, or $59/mo billed annually, $708 a year): 6,500 credits (about 75 minutes, or about 70 by the pricing page's estimate), 180+ avatars, 5 personal avatars, branded pages and interactive video. Pro also comes in 2x to 8x credit tiers ($176 to $676 a month billed monthly, or $117 to $448 a month billed annually).
• Enterprise (custom): unlimited minutes, the full avatar library and one-click translation into 140+ languages.

On monthly billing, Synthesia currently shows a lower first month: $9 on Starter and $49 on Pro, then the regular price (checked Nov 7, 2026).

Example: a course creator releasing four 10-minute lessons a month. Assumptions: about 100 credits per finished minute, no dubbing, prices as of Nov 7, 2026. Forty minutes exceeds Starter's roughly 27 (about 22 by the pricing page's estimate), so it's Pro at $89 a month, or $59 billed annually. Two lessons a month fits Starter.

Who should pick it (and who shouldn't)

Pick it if you produce neutral, evergreen teaching content at volume, or need the same lesson in several languages. Skip it if your content is opinion, reviews, news or sponsored, and you won't make a personal avatar, or if you're happy on camera already.

Alternatives worth comparing

• HeyGen, the closest avatar-video rival.
• ElevenLabs if voice alone will do; compared in ElevenLabs vs Synthesia.
• Workflow ideas in the best tools for course creators and the branded AI presentation workflow.

What changed (Oct 7, 2026)

• Plan names, prices and limits now match Synthesia's official pricing page as checked on Oct 7, 2026.
• We removed first-person usage claims, because this review is editorially reviewed rather than hands-on.

What changed (Nov 7, 2026)

• Re-checked Synthesia's pricing page on Nov 7, 2026. Starter is now $19 a month, or $14 billed annually ($168 a year), and Pro billed annually is $59 a month ($708 a year). Pro's monthly price ($89) is unchanged.
• The yearly prices of Pro's larger credit tiers are updated, and we now show the pricing page's lower minute estimates next to the help center's.
• HeyGen is no longer described as having the cheaper entry plan.
