Choose Synthesia if…

Where they differ
- Fit & support: Arcads leads Synthesia, 8/10 to 6/10. How well the tool fits a specific job (app ads, e-commerce, B2B, localisation), plus onboarding, docs, and support quality.
- Output realism: Arcads leads Synthesia, 9/10 to 8/10. How believable the AI actor / avatar / voice looks and sounds. Lip-sync, hands, and audio naturalness. The thing that decides whether an ad reads as human.
- Workflow & speed: Arcads leads Synthesia, 8/10 to 7/10. How fast you get from idea to a usable ad, and how much manual editing is left over. Batch generation, script tools, hooks, captions, variations.
- Actors & languages: Arcads leads Synthesia, 9/10 to 8/10. Breadth of AI actors/avatars, custom-avatar support, and language/accent coverage. Matters most for localisation and for finding a face that fits your brand.
Effectively tied: value for money.
Arcads in one line
The most believable AI actors in the category, best justified when you are shipping dozens of ad variations a month rather than a handful.
Synthesia in one line
The enterprise standard for avatar video in training and internal comms - included for context, but the wrong tool for scrappy performance-ad UGC.
