About Synthesia

Synthesia occupies a distinct niche from cinematic text-to-video generators like Runway or Sora: it specializes in AI avatar-based, talking-head videos for corporate training, onboarding, and internal communications, and is widely considered the undisputed leader in that category, trusted by 90% of Fortune 100 companies. It requires no cameras or recording equipment, converting a script directly into a professional-looking presenter video with strong text-to-speech that significantly reduces production time. Pricing starts free with 10 video minutes per month, scaling through a Starter tier around $29/month, with G2 reviewers rating it 4.6/5 from over 2,500 reviews and specifically praising its modern, well-organized interface for collaborative teams. It is not a fit for cinematic B-roll, ads, or creative scene generation, that is a different product category entirely, but for compliance training and enterprise communications specifically, reviewers consistently rank it above HeyGen on polish and scale.
