Synthesia

Synthesia makes videos from text. You write a script, pick an AI avatar to deliver it, and get a finished video back in minutes, with no camera, studio, or voice actor in the room. It is aimed squarely at business use, and the company says it is used across 50,000 teams and by 90% of the Fortune 100, with more than a million people on the platform.

The core is the avatar and the voice. Synthesia offers 240+ AI avatars and voiceovers in 160+ languages, backed by a library of over 1,000 voices. You type your script in the language you want, the avatar speaks it, and captions are generated automatically. The avatars are the reason to be here: they are expressive enough to carry an explainer or a training module without slipping into the stiff, robotic look that gives cheaper tools away.

Beyond generating a talking head, there is a real editor around it. You get templates to start from, a Brand Kit that keeps logos and colours consistent, AI motion graphics, and an AI screen recorder for product walkthroughs. There is even an AI script generator if you are staring at a blank page. It reads less like a toy and more like a video tool that happens to remove the film crew.

Where Synthesia earns its keep for bigger teams is translation and reuse. One click translates a finished video into any of the 160+ supported languages, and newer AI dubbing and a multilingual player let one recording serve a global audience. The results customers report are the selling point: Mondelez cut 100 hours of translation work down to about 10 minutes, and Zoom says it makes videos 90% faster than before.

For the people who have to manage all this, there is live team collaboration, workspaces, version control, and SCORM export so training videos drop straight into an LMS. You can publish to public or SSO-protected pages and then see analytics on views, drop-off, and completion, so a course or an onboarding video is not just shipped and forgotten. Custom avatars let you turn your own presenter, or a real employee, into a reusable digital version.

Security is handled at a level enterprises need. Synthesia is SOC 2 Type II, GDPR, and ISO 42001 compliant (the standard for AI management systems), with SAML and SSO for access. That is a big part of why regulated names like Merck, SAP, Moody's, and Heineken are comfortable using it.

One thing to weigh: this is a business tool priced by video minutes, so long or high-volume output costs real money, and avatar video suits explainers, training, and updates more than cinematic or heavily filmed content. There is a free tier to test it (10 minutes a month, 9 avatars, and the full voice library, no card required), which is enough to judge the avatars before you pay. With a 4.7 out of 5 on G2 from more than 2,000 reviews, it sits at the front of this category for a reason.
