Synthesia
What is Synthesia?
AI video creation platform used by enterprises to produce training videos and presentations with photorealistic AI avatars.
Synthesia creates training and presentation videos with photorealistic AI avatars, so you need no filming, actors or studio. You write a script, pick an avatar and a language from 140+ options, and use corporate templates, screen recording and media import, with enterprise compliance features aimed at large organizations. The free Basic plan gives 10 minutes of video a month, then Starter is $29 a month ($18 billed yearly) and Pro is $89 a month ($64 billed yearly), with custom Enterprise pricing. Plans are credit-based, so check current allowances on Synthesia's pricing page. There is no usable free tier for real projects, costs scale quickly with video minutes, and avatars can still feel slightly uncanny. HeyGen covers similar ground at a friendlier price for individual creators.

Best Synthesia alternatives
HeyGen
A close competitor with a very similar avatar-and-script workflow, often cheaper for individual creators.
Descript
Better if you are editing real filmed footage of a person rather than generating an avatar video.
InVideo AI
A cheaper option for simpler marketing videos that do not need a realistic corporate presenter avatar.
Is Synthesia worth it?
Synthesia is the most enterprise-ready AI avatar video tool, with compliance certifications and 140+ language support that matter for large-organization training content. It's a poor fit for individual creators or small budgets given the lack of a generous free tier -- HeyGen covers similar ground at a friendlier price point for that audience.
