Become a better
dog parent.

Voicari combines 24/7 emotion and health insights with live GPS and PetGPT, your AI companion, to help you understand how your dog feels, sleeps and moves, from day one.

Voicari gives your dog a voice.

And gives you everything you need to understand it.

Why Voicari
Emotion

Know how your dog feels

24 emotional states across 7 core emotional families, read from vocalizations together with heart rate, respiration and activity.

Bruno
Separation anxiety

Bruno would bark the moment I closed the door, and I never knew if it took him seconds or hours to calm down. Voicari showed me that his barking was actually anxious barking, not just boredom, like I had long assumed. After two months, he barely barks anymore when I leave the house.

Health

Wellness insights, not guesswork

Heart rate, respiratory rate and activity, tracked continuously and turned into clear wellness insights.

Milo
Rescue dog from abroad

When we adopted Milo from Romania, he would constantly pace back and forth restlessly in certain situations and bark a lot while doing it, and we never knew exactly why. Voicari showed us that this restlessness always repeated in the same moments, a pattern that had been completely hidden from us before. Today he moves around much less in these moments and barks noticeably less too.

Sleep

See how your dog really rests

Nightly rest and daytime naps, tracked continuously. Dogs sleep far more than most owners expect, so you can see when that changes.

Rocky
Dog encounters

At the dog park, it almost looked like a fight between our Rocky and another dog, and I was genuinely startled for a moment. Voicari showed me afterward that it was actually still well within a safe range and both dogs were only 'playing,' even though it felt different to me in the moment.

GPS

Always know where they are

Live GPS with safe zones and escape alerts, plus walks, activity and rest history for every day.

Faula
Dog walker & daycare

I always felt guilty when Faula was with the dog walker, simply because I didn't know how she was really doing. I trust the situation a lot more now, because I can actually understand what's happening.

Safe zones

Know the moment they get out

Draw a zone around home, the garden or the park. You get an alert the moment your dog leaves it, with live location from there on.

Luna
Training success, finally measurable

With Voicari, I could see in black and white that Luna's frustration during leash training was actually decreasing week by week. Without the data, I probably would have given up.

PetGPT

Ask anything about your dog

A personal AI companion that answers your questions using your own dog’s data, not generic advice.

Luna
Training success, finally measurable

With Voicari, I could see in black and white that Luna's frustration during leash training was actually decreasing week by week. Without the data, I probably would have given up.

Why does Luna bark when I leave?

Her barks cluster in the first 20 minutes after you go, then stop. That reads as separation stress rather than reacting to noises outside.

What early owners value most

Real reassurance comes from understanding what's happening when you're not sure what your dog is trying to tell you.
