HeyGen and Captions both offer AI avatar generation, but from different starting points. HeyGen is a dedicated avatar platform — the avatar and its realism, language coverage, and lip-sync quality are the entire product. Captions started as a footage editor and added an avatar feature (Mirage Avatar X) on top, so the avatar is one capability among a broader editing toolkit.
HeyGen offers 500+ stock avatars on its free tier alone, custom digital twins on paid plans, and lip-sync across 175+ languages — the deepest avatar-specific feature set of the two.
Captions offers Mirage Avatar X for digital-twin and AI Actor generation, plus AI Edit (automated cuts, B-roll, transitions from raw footage), eye-contact correction, and captions/translation in 100+ languages — a smaller, less specialized avatar pool than HeyGen's, but genuine footage-editing capability HeyGen doesn't have.
| HeyGen | Captions | |
|---|---|---|
| Free tier | Yes — 3 videos/month | Yes — basic editing, no avatar |
| Entry | $29/month (600 credits) | $24.99/month (500 credits, avatar included) |
| Mid-tier | $49/month (1,000 credits, 4K) | $69.99–$279.99/month (1,400–5,600 credits) |
| Top tier | $149/month + $20/seat (Business) | Enterprise custom |
The two are similarly priced at entry, with HeyGen offering deeper avatar realism and language coverage, and Captions offering footage editing HeyGen doesn't provide.

HeyGen — its avatar-specific focus (500+ avatars, custom digital twins, 175+ languages) goes deeper than Captions' Mirage Avatar X, which is a secondary feature of an editing product.
Yes — Captions' AI Edit handles automated cuts, B-roll, and transitions from raw footage, a capability HeyGen doesn't offer.
They're comparably priced at entry ($29 vs $24.99/month), with the practical difference being what's bundled: HeyGen's avatar depth vs. Captions' editing suite.
No — neither ingests a product URL or publishes directly to ad accounts. Both are general-purpose platforms that can be used for ecommerce ads without being purpose-built for that workflow.
