Full-text search across app store and Google Maps reviews
Problem
When choosing a restaurant or an app, users often need to know one specific thing ('does it have parking?', 'does it work offline?') but reviews on Google Maps and the Apple App Store are not full-text searchable — you have to scroll hundreds of reviews hoping to stumble on the answer. Airbnb solved this years ago and it's still missing elsewhere.
Opportunity
A tool (web app or browser extension) that ingests reviews for any place or app and lets users keyword-search them, plus AI summaries per keyword. Scraping/API constraints are the moat; distribution via SEO pages like 'X restaurant parking reviews' is a natural wedge.
Market analysis
Airbnb-style keyword search over reviews is a proven UX pattern, and at least one Chrome extension already does it for Google Maps, while Google itself ships popular-keyword filter chips on listings. The app-store side is less served and has official APIs, but the SEO-wedge business lives or dies on scraping longevity.
Market · High-intent researchers picking restaurants, apps and services; diffuse consumer demand, with programmatic SEO ('X restaurant parking reviews') as the real traffic asset.
Pricing · Consumer extensions are free or a few dollars a month; the durable money is B2B review analytics (Localith, EmbedSocial and similar) at tens of dollars per month per business.
Pros
- + Airbnb validated the exact UX; users understand it instantly.
- + Programmatic SEO pages create a compounding distribution wedge.
- + App-store reviews are accessible through official APIs, no scraping needed.
Cons
- − A Chrome extension for Google Maps review search already exists.
- − Google Maps scraping violates ToS and becomes a cat-and-mouse maintenance treadmill.
- − Google can absorb the feature natively (keyword filter chips already exist).
- − Consumer willingness to pay for a search box is close to zero.

The consumer wedge has no monetizable depth on its own; the durable business is the B2B side, where multi-location brands already pay for keyword analytics over their reviews, and consumer SEO pages are just top-of-funnel. The Maps half is a trap (ToS cat-and-mouse, an existing extension, native filter chips), while the app-store half has official review APIs and no visible incumbent, so that is where a solo builder should start. Expect the moat to be index freshness and coverage, not the search box itself.
