At-home cat scan

Love this simple to use app. It’s an added signal to measure my cat’s wellbeing. I uploaded photos of my since passed cats in the final weeks and it confirms they were uncomfortable.

An amazing tool to help support your cat’s health

I recently tried Sylvester AI using a photo of my cat, Meep, taken about a month before we had to say goodbye. The platform indicated it was 98% confident she wasn’t doing well. Honestly, that brought me a lot of comfort.

At the time, making that decision was incredibly hard, but seeing that insight helped reassure me that we did the right thing for her. While no tool can replace veterinary care, this felt like a supportive, validating second perspective.

I’d recommend Sylvester AI to any cat owner who wants an additional layer of understanding about their pet’s wellbeing.

Post Surgical pain management

I loved using this App to help me determine how my 2 cats were feeling after their neuters. I was able to follow them with daily scans through their recovery and discover when they returned to their baseline mood. This tool is so unique. I would recommend it to anyone who has a pet go through surgery to monitor their mood post op!

Love!

I spoke to my veterinarian who recommended this app - it’s basic but it works! My cat scans as “unhappy” whenever I get ready to leave, and also whenever she’s in the carrier.

Can’t access & they refuse to refund

I bought the 1 year subscription but couldn’t login after creating my account. I contacted their support weekly for about a month and kept being told “waiting for tech” to respond. I finally just requested a refund and still was told to wait for tech. No refund. Can’t use the app. No response other than wait for tech. Seems like a scam or poorly run business.

Thanks for writing in, and we are sorry for the frustration here. We are a small team and this sounds like a login issue that took longer than it should have to resolve. We are a real, actively supported app and do process refunds when requested.
