PetFitly — Pet Product Fit Checker

Check whether pet food and supplies fit your pet profile, with evidence, confidence, costs, and safety signals.

PetFitly helps you understand whether a product page matches the pet profile you selected before you buy. On supported Amazon, Chewy, and Petco product pages, open the side panel and choose “Check this product”. 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 and profile sync remain off until you enable them in Settings. 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 languages: English, 简体中文, Español, Deutsch, Français.
