Synthesia x Polar: turn your winning ads into your next batch of video.

Polar knows which ads actually work, by ROAS, by angle, by audience. Connect it over MCP and an AI creative agent reads your winners every day and spins them into fresh angles, then produces spokesperson and UGC-style video ads in Synthesia. Your best-performing creative becomes the brief for the next batch, automatically.

Synthesia makes video. Polar tells it what to make.

A video generator is only as good as its brief, and most briefs are guesses. Polar gives Synthesia a brief grounded in what actually converts: your winning ads, by ROAS, angle and audience.

Synthesia on its own

  • Great video, briefed on a hunch.
  • No idea which angles actually convert.
  • Output disconnected from performance.
  • You guess what to make next.

Synthesia with Polar

  • Video briefed by your winning ads, by ROAS and angle.
  • New angles spun from what's already converting.
  • Performance loops back to pick the next batch.
  • The best ads become the brief, automatically.

Featured Use Case

Your winners, briefing the next batch.

Your winners, briefing the next batch

A video tool can make anything; the hard part is knowing what to make, and that is exactly what a creative team burns time guessing. Polar closes the loop: it reads which of your ads are winning, by ROAS, angle and audience, and hands Synthesia a brief grounded in real performance. Every day it spins your winners into new angles and produces spokesperson and UGC-style video ads, on-brand and ready to test, then reads the results back to pick tomorrow's winners. Your best creative stops being a one-off and starts compounding.

What makes it real

From your winners. The batch starts from the ads Polar shows are winning, not a hunch.

Produced for you. Spokesperson and ugc-style video ads generated in Synthesia, on-brand, ready to test.

Ask Polar, in plain language. “Spin our top 3 ads into 10 new video each.” No SQL, no export.s
