Understand your cat’s comfort at home
The Sylvester app helps you better understand your cat's comfort using computer vision and recognized feline pain science.
A simple photo translates subtle facial cues into instant insights, making it easier to notice changes and stay in tune with your cat's wellbeing.
So you can see more, and know sooner.
Because feline pain is hard to spot
Sylvester.ai combines computer vision with recognized feline pain science to translate subtle facial cues into instant insights, making it easier to stay in tune with your cat’s wellbeing.
Our goal is simple: to remove the guesswork from caregiving by empowering clinics, platforms, and cat caregivers with objective comfort insights so you can track changes over time with confidence.
Built Just for Cats
General AI tools look at everything on the web, but Sylvester is different. Sylvester is trained exclusively on highly specialized cat data through unique animal shelter partnerships, creating a reliable tracking tool built from the ground up specifically for your cat.
Our unique technology is officially patented, meaning it is a one-of-a-kind tool proven to read feline facial expressions that you can trust.
Science-Backed
You don't have to be a veterinary expert to use recognized feline science. Sylvester is built directly around validated veterinary research which proved that cats show comfort and discomfort through their facial expressions and posture.
The Sylvester app turns this complex scientific research into a simple, everyday tool that anyone can use right from their smartphone.
Snap. Check. Know.
Understanding your cat shouldn’t be complicated or difficult. Sylvester gives you an easy, low-stress way to check in on your cat’s daily wellbeing without any fuss.
Simply open the app, snap a quick photo during a calm moment, and get instant, objective comfort insights that help you stay in tune with their comfort over time with confidence.
