Synthesia vs HeyGen vs Descript: which AI for training & avatar video?
Don't pick a brand, pick the job. All three show up in avatar / talking-head workflows, but they sit in different places: Synthesia is built for business training, explainer, and marketing avatar video (140+ languages, AI dubbing, PowerPoint import), HeyGen is creator-style AI avatar video from a script (no camera or crew), and Descript edits your own recorded talking-head by editing the transcript. This page is about avatar / training video stacks — for avatar vs custom TTS vs edit your recording see HeyGen vs ElevenLabs vs Descript; for generative clip vs avatar vs transcript edit see Runway vs HeyGen vs Descript. Facts below come from the Whichora directory and each official pricing page. Prices change, so re-check before you pay. Not financial or legal advice. Last checked 2026-10-16.

- Ship one real artifact — a 30–60s training/explainer clip, a creator avatar from a script, or a cut of footage you already recorded — not a demo prompt.
- Check commercial-use terms, watermarks, likeness/consent rules, and credit caps on your plan before you publish.
- Pay only when free limits bite every week, and re-check the official page for current USD and credits (Starter annual is about USD 18/mo on the official yearly toggle (monthly USD 29/mo)).
- If you need business/training/explainer avatars (especially multilingual), prefer Synthesia; if you need creator-style script → avatar video, prefer HeyGen; if you need to edit your own recorded talking-head by transcript, prefer Descript.
