Product review research
Why it works.
Reviews on video are long, and the useful part is often one sentence in minute twelve. Across ten reviews, that is hours of watching. With transcripts, your AI reads all of them and collects the points that come up again and again.
For your own product, this shows how reviewers describe it in their own words. For a competitor’s, it shows the weak spots that reviewers keep coming back to.
Who uses it
- Product managers and market researchers
- E-commerce brands watching their category
- Shoppers comparing products before buying

iPhone 17 Pro Review: Paradox in a Box!
Marques Brownlee
- 0:00- The best thing about the iPhone Air is actually how much it seems to have freed Apple up to make the Pro phones even more pro.
- 0:10(slow dramatic techno music)
- 0:22(slow dramatic techno music continues)
- 0:35(slow dramatic techno music fading) Have you noticed that?
- 0:41These new Pro phones are thicker than last year, more room inside for bigger batteries, and a vapor chamber, and a bigger camera.
- 0:48It's not quite on the level of the Ultra phones, but this is the most maximalist that an iPhone has ever felt, and I like it.
- 0:57But also, let me let you in on a little not-so-secret secret. The Pro phone is always the best selling one.
- 1:04Like this year, the iPhone Air is the most interesting and it's getting the most YouTube clicks and the most views, but then the Base 17 is more than ever the one that most people should get and the best deal.
