Synthesia is an AI video creation platform that lets you produce professional presenter videos without cameras, studios, or actors. You write a script, choose from 230+ AI avatars, select a language, and the platform generates a polished video with synchronized speech in minutes. It's used by over 50,000 companies for training content, product explainers, and multilingual communication.
We tested Synthesia across 30 days of real business video production — creating training modules, product demos, and multilingual content — to give you a complete picture of its strengths and where it falls short.
Synthesia offers a free Basic plan with 3 minutes of video per month and limited avatars. The Starter plan at $18/month (annual) provides 10 minutes per month and access to 90+ avatars — the minimum viable plan for business use. The Creator plan at $64/month jumps to 30 minutes and adds custom avatar creation.
The video minute limits are the biggest friction point. Ten minutes per month on Starter sounds reasonable until you realize that's 10 one-minute videos, or 2 five-minute explainers. Teams producing regular training content will hit the ceiling quickly and face a costly jump to Creator.
Synthesia is purpose-built for corporate L&D teams, HR departments, and global marketing teams who need professional presenter videos at scale without production overhead. The multilingual lip-sync translation — converting one English video into 10 languages automatically — is the killer feature for global organizations.
It's not the right tool for creative video work, social media content, or anyone who needs more than 30 minutes of video per month without enterprise pricing. For those use cases, Runway or HeyGen are better fits.

Try Synthesia Free →Synthesia is the market leader for AI avatar business video for good reason — the multilingual capabilities, avatar quality, and ease of use are consistently strong. But the video minute limits on paid plans feel restrictive relative to the price, and the $1,000/year custom avatar add-on is a steep ask. For corporate training and multilingual content at scale, it's the best tool available. For everything else, look elsewhere.
