What it does

Three things, fast.

01 · Search

Concept-level search.

Every review is embedded into a 1024-d vector. Ask in natural language — "users frustrated by paywall after a free trial" — and get the closest matches across all competitors.

02 · Personas

Synthetic focus groups.

Personas are clustered from real review patterns: ad-fatigued readers, paywall refugees, crash reporters. Talk to them in Claude with their actual quotes as evidence.

03 · Trends

Themes & sentiment.

Auto-tagged across notifications, ads, paywalls, performance, and more. Compare publication-by-publication, slice by rating, watch shifts after major releases.

Ask in plain English.

"What do Bloomberg users say about the watchlist?" "Run a focus group on charging $2 more for ad-free." Claude picks the right tool and answers with real quotes.

Roadmap

News today, more tomorrow.

News apps are first because they're loud, opinionated, and well-reviewed. The same pipeline — embed every review, cluster into personas, expose to Claude — extends to any consumer category. Up next: finance, health & fitness, productivity, streaming. If you have a category you'd like indexed, get in touch.
