What is an AI b roll generator?

An AI-powered tool that reads your video script and automatically selects matching supplemental footage from a stock library, removing the need for manual clip searches.

Can I use the b-roll commercially?

Yes, all footage from our 4M+ clip library is fully licensed for commercial use in ads, client work, and monetized content.

How does the AI choose footage?

The AI analyzes the meaning of each sentence in your script and matches it against the clip library, selecting footage that visually supports your narration.

Do I need video editing experience?

No, the generator assembles the b-roll into a complete timeline for you. You can review and swap clips with a click, no editing software required.

Can I replace clips the AI selects?

Yes, every clip can be swapped for an alternative suggestion or a different search result, so the final video always matches your vision.
