Descript 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 cut-down and repurposed video variations in Descript. Your best-performing creative becomes the brief for the next batch, automatically.

Side by side
Descript 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 Descript a brief grounded in what actually converts: your winning ads, by ROAS, angle and audience.
