Compara.cat

Compara.cat is the personal project of ex-Google engineer Marcel Pintó Biescas (founder of pibi.studio): generative AI distills Amazon and other e-commerce reviews into pros/cons summaries, focused on the Catalan content ecosystem. Entirely free with no paid tiers and running on Amazon Affiliate commissions, it survives as a minority-language option after Fakespot and ReviewMeta shut down.

Core Capabilities

• Analyze on paste: Drop an Amazon/eBay/Walmart link and the AI quickly outputs a pros/cons summary
• Fake review filtering: Removes suspected astroturfing and biased reviews using signals like helpful votes and verified purchases
• Conversational follow-ups: Keep asking questions after the summary to dig into product details (v1.3.0+)
• Cross-platform parity: Web, iOS, Android, and Chrome extension all available, with instant invocation inside Chrome
• Price tracking: Track price movements in the app to inform comparison decisions
• Completely free: No subscription or in-app purchases; revenue comes from Amazon Affiliate commissions

Use Cases Best for Catalan/Spanish speakers making frequent purchases on Spanish and Italian Amazon, and for lightweight users seeking a Fakespot replacement — near-zero friction, results in three steps. Hardcore users needing strict fake-review detection or long-term price tracking should pick Keepa or BuyWise.

Unique Advantages Most directories wrongly say 'web only' or 'Catalan only,' when in fact all four platforms exist with a trilingual UI (CA/ES/EN); the founder publicly commits to decoupling commissions from recommendations, rare transparency in this category. But the App Store's sole 1-star complaint alleges the app asks for Amazon passwords with no official response, conflicting with the 'no login needed' pitch — stay cautious.

Editorial Review The engineering foundation (Flutter + Vertex AI) keeps quality above a floor, but with 5-12K monthly visits, an app rating of 1.0 or zero ratings, and a slow operating cadence, it is a 'taste-test grade' personal project — rating 3/5. Worth a try for Catalan/Spanish shopping audiences; general users are safer with BuyWise or Amazon Rufus.
