Quick verdict: Synthesia earns 4.4/5 in our research-based assessment — the category reference point for avatar video. Pick it when avatar and language breadth, the drag-and-drop Brand library or a clean API are the decision driver; the $18/mo annual Starter and $64-89/mo Creator tiers are where most teams land. For a more usable free tier with three watermarked videos a month, HeyGen is the pick; for the biggest free minute allowance plus SCORM export, Colossyan; for the cheapest paid entry, D-ID at $4.70/mo annual. The premium you pay is for the largest avatar and language surface in the set. (Research sweep, no paid workspace tested.)
