The main difference between Probably and HeyGen
Choose Probably for UGC-style ads made and reviewed for you from a brief; choose HeyGen for avatar video in many languages, long videos or uses beyond ads.
Probably makes one thing, UGC-style video ads. HeyGen is a broader avatar and video-translation platform for marketing, training, sales and localization, with a UGC ads maker among its tools.
Probably vs HeyGen: how you make an ad
In Probably you describe the ad and a crew of AI specialists writes, casts, films and edits it. In HeyGen you start from a URL or build the video yourself in AI Studio.
HeyGen's URL-to-Video takes a blog post, landing page or Shopify or Etsy link, lets you pick a style and edit the script, and renders a captioned MP4. Its UGC ads page shows an "+ Add product" label but doesn't describe product-in-hand shots.
| Step | Probably | HeyGen |
|---|---|---|
| Start | A sentence, plus optional photos, notes or a reference link | A URL, or a project in AI Studio |
| Script | Written by the crew, editable by you | Generated from the URL, editable by you |
| Look of the footage | A creator style per scene, with a phone finish | A style you pick; avatars meant to feel like real creators |
| Formats | 9:16, 1:1 and 16:9 | 16:9, 1:1 and 9:16 (URL-to-Video) |
