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.

Emotion

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. With targeted training against the separation anxiety, I could then really see how his stress levels went down over the weeks. After two months, he barely barks anymore when I leave the house. For the first time, I had proof that the training actually works, not just my gut feeling.

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. With PetGPT, we then worked specifically on exactly those situations. Today he moves around much less in these moments and barks noticeably less too. I often felt like I wasn't doing right by him, and that has gotten a lot better now.

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. Through PetGPT, I then got tips on what to watch for next time. That gives me a lot more confidence now when it comes to encounters with other dogs. Next time, I'll try out the recording feature with the smartphone camera.

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. Through the app, I could see that she was out and about a lot and played extensively with others, and her barking during that was clearly 'happy,' not stressed or negative barking. That gave me a peace of mind I hadn't had before. I trust the situation a lot more now, because I can actually understand what's happening.

Luna
Training success, finally measurable

After three months of expensive one-on-one training, I honestly didn't know if we were making any progress at all, or if I was just burning through money. With Voicari, I could see in black and white that Luna's frustration during leash training was actually decreasing week by week. That gave me real confidence for the first time that the exercises were working. Without the data, I probably would have given up. Through PetGPT, I then got matching exercises for everyday life, tailored exactly to her situation.

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.
