Synthesia and Captions both generate AI avatar video, but for very different audiences. Synthesia's customer list (Heineken, Merck, SAP, Zoom, Mondelez) signals enterprise training and compliance content, backed by governance features like SCORM export and SSO. Captions serves a much broader mix of individual creators and businesses, with its avatar feature (Mirage Avatar X) added on top of an AI video editing product.
Synthesia offers custom on-brand avatars, translation into 160+ languages, SCORM export for LMS integration, and SSO — built for Fortune 100-scale training and internal communications, priced by video minutes per month.
Captions offers AI Edit for automated footage editing, Mirage Avatar X for avatar generation, eye-contact correction, and captions/translation in 100+ languages, priced by credits rather than minutes — a structure that suits producing more, shorter clips.
| Synthesia | Captions | |
|---|---|---|
| Free tier | Yes — 10 min/month, 1 avatar | Yes — basic editing, no avatar |
| Entry | $29/month (10 min/month, 3 avatars) | $24.99/month (500 credits, avatar included) |
| Mid-tier | $89/month (30 min/month, 5 avatars) | $69.99–$279.99/month (1,400–5,600 credits) |
| Metering | Per video minute | Per credit |
Synthesia's minutes-based quota suits fewer, longer, more polished videos; Captions' credit system suits producing more, shorter clips — a structural difference more than a simple price comparison.

Captions — its credit-based pricing and editing tools suit producing more, shorter clips better than Synthesia's minutes-metered structure, which is built for fewer, longer videos.
Synthesia — SCORM export and SSO are built specifically for enterprise L&D and compliance use cases, which Captions doesn't offer.
Captions, generally — its credit system scales better for volume than Synthesia's per-minute metering, which caps out fast for short-form content.
No — both are avatar/video platforms only.
