How the entry plans compare
Both tools price AI avatar video in credits. HeyGen's Creator plan cost $29 a month on 9 October 2026 ($24 billed yearly) for 600 credits, with videos up to 30 minutes. Synthesia's Starter plan cost $19 a month ($14 billed yearly) for 1,250 credits a month. Synthesia says a minute of video uses about 100 credits.
The credits are not the same unit, so the totals don't compare directly. We haven't measured how many minutes each plan actually produces yet. Both free plans brand the output: Synthesia's carry a watermark, and HeyGen lists watermark removal only on paid plans.
