Synthesia vs HeyGen: free AI video plans compared
Deals checked 22 Oct 2026
Both let you make AI avatar videos for free, with a watermark. Synthesia's free Basic plan gives you 10 minutes of video or dubbing plus 500 credits a month. HeyGen's free plan gives you 3 videos a month, each up to 1 minute. One counts minutes and the other counts videos, so the better fit depends on how long your videos are.
