Our verdict
It depends on your prioritiesThe two best-known avatar platforms, one metered in minutes and the other in credits.
TechBigs verdict, published Sep 4, 2026
Synthesia is easier to budget because its plans state minutes as well as credits, and its Creator tier includes API access. HeyGen is the better choice for 4K output and the largest avatar and language library, and its free plan lets you make three real videos.
Read the full analysis
What you get for nothing
Synthesia's free Basic plan gives 1,200 credits a month, which the page describes as about ten minutes of video, on one editor seat. HeyGen's free plan gives three videos of at most one minute each. Ten minutes a month is more useful for evaluating a workflow; three complete short videos is more useful for judging output quality.
How the paid tiers are measured
Synthesia sells annual credit pools: 14,500 credits a year on Starter at US$18 a month, about two hours of video; 44,000 on Creator at US$64, about six hours. HeyGen sells monthly credits: 600 on Creator at US$29, 1,000 on Pro at US$49, 1,500 on Business at US$149. The Business tier also raises the maximum video length from thirty minutes to sixty.
Seats, avatars and export
Synthesia counts editors and guests separately: one editor with three guests on Starter, five guests on Creator, which suits a small team reviewing work. HeyGen's published tiers below Business are single-seat. It states 4K export from Pro, five or more custom avatars on Business, and more than 175 languages. Synthesia states 125 or more stock avatars, five personal avatars on Creator, and 160 or more languages.
