AI ad video generator
Motion hooks, product demos and lifestyle b-roll for TikTok, Reels, Shorts, Meta and YouTube. Same locked creator, every variant. Test 20 hooks in an afternoon.
No credit card. Free credits on signup. Commercial use on every tier.






Short-form ad creative is the highest-leverage variable in the funnel — and the most expensive to iterate. A real shoot is $5K–$50K and weeks for one set of variants. By the time it lands, the platform has changed.
Synexa renders the same variants in minutes. Lock the creator, write 20 hooks, render them all, ship the winner. Iteration cost collapses; ad quality goes up.
Most AI video tools change the face every generation, so a 20-variant test becomes a 20-creator test — and you can't tell which hook is winning vs which creator is winning. Synexa locks identity at the avatar level so the variable you're testing is the hook, not the face.
Vertical 9:16 for TikTok / Reels / Shorts / Stories. Square 1:1 for Meta feed. 16:9 for YouTube pre-roll. 5 or 10 second clips, up to 1080p, no watermark. Full commercial license on every tier.
