PetFitly — Pet Product Fit Checker

Check a supported Amazon, Chewy, or Petco product before you buy: 1. Open the product page and the PetFitly side panel. 2. Select or create a pet profile. 3. Choose “Check this product” to see the fit result, risks, confidence, and evidence. No account is required for local checks. PetFitly extracts structured facts from the current page and shows: • a deterministic match result with confidence and field-level evidence; • species, life-stage, allergen, label, size, load, material, and maintenance checks appropriate to the product category and selected species; • dry-matter nutrition comparison for supported cat and dog foods; • estimated use cost when the page provides enough data; • saved products, recent analyses, and comparison of up to four compatible results on Pro; • price and recall alerts, and user-requested packaging-photo extraction on Pro. Profiles support dogs, cats, birds, rabbits, guinea pigs, hamsters, ferrets, reptiles, fish, and other companion animals. Species-specific nutrition scoring currently covers cats and dogs; other species receive label and specification comparison only where a dedicated rule is available. Pet profiles and results stay in Chrome by default. Google sign-in is optional. Cloud analysis, profile sync, and anonymous usage analytics are separate and off until you enable them in Settings. Anonymous analytics never includes product URLs or titles, pet names, weight, allergies, health details, or browsing history. PetFitly analyzes only the active supported product page after a user action and does not collect complete browsing history, cookies, credentials, or payment-card numbers. PetFitly provides product information, not veterinary diagnosis or treatment. Always confirm labels, dimensions, lot codes, recalls, and veterinary dietary guidance before use. Supported interface languages: English, Simplified Chinese, Spanish, German, French. Product details remain in English.
