Teach your cats what not to do.

Event-based actions

Place the Sentry, then type the rule the way you'd tell a cat-sitter — “Mochi stays off the kitchen counter.” The AI works out what to watch for, and answers with a buzz on her collar or an ultrasonic cue. Only for the cat breaking the rule.

On-device AI No sprays, no shocks Rules in plain words Modular — add rooms later

Why it works

01

It knows which cat

You name her in the sentence and the collar Tag does the rest. A rule applies to Mochi and not to Yuzu — same kitchen, same counter, same minute.

02

It knows what she's doing

Vision runs on the Sentry itself and reads posture, not movement. “Off the counter” means four paws on the surface — not walking past it, not sleeping beside it, not a curtain moving at night.

03

It answers once

A short haptic buzz on her collar — surprising, never painful — or a directional ultrasonic cue at 22–25 kHz from the Chirp. Both stop the moment she does, and the room hears nothing either way.

Humane by design

Nothing is sprayed, shocked, or thrown

A cue is a half-second buzz on the collar or a tone she alone can hear, and it stops the moment she steps down. Because the system only fires for the right cat in the right place, she forms the one association that matters — and the other cat never learns to fear the kitchen.

The Sentry held between finger and thumb
The app

Type the rule. That's the setup.

No zones to draw, no menus of behaviours. You write a sentence, the AI reads the camera against it — and every cue arrives with the two-second clip that caused it, so one tap corrects a mistake.

What it never does

  • Fire at a cat your sentence didn't name
  • Spray, shock, or startle with a loud noise — the buzz is a nudge, at a fraction of a phone’s vibration
  • Send video off the device without you asking
  • Run a cue longer than the behaviour lasts
  • Guess: if a sentence is ambiguous, it asks before it arms

Range and coverage

  • One Sentry covers a 4 × 5 m room, up to four zones
  • One Chirp covers a 2.5 m arc — one counter run, one doorway
  • Tags reach 18 m indoors, six weeks per charge, buzz in 90 ms
  • Modules mesh directly; no hub needed

counter surface

Watch Mochi for four paws on the counter. Ignore Yuzu. Answer with one buzz on her collar.

Found the counter on your camera. Change any part by rewriting the sentence.

Rules — you type it, the AI builds it

“Yuzu learned the counter in four days. Mochi still doesn't know the system exists — she was never the problem.”

Start with one surface

The Starter Kit is a Sentry and one collar — €229, one cat, one surface. Add Tags and Chirps whenever the problem moves; the app finds them on its own.
