How Haku works

Three steps.
One happier cat.

No special hardware. No vet visit. Just your phone and your cat.

01

Film for 10 seconds.

Open Haku. Tap record. Point at your cat. That's it — let them sit, walk, eat, anything. Haku tracks their face, body, tail, and ears live, and you can see it working: amber dots lock onto them as you film.

  • Captures 8 frames + audio over 10 seconds
  • Works in any lighting, indoors or out
  • No need to chase or pose — natural behavior is best

Reading for Haku

Content & observant

Haku is relaxed, settled in a sunbeam, eyes half-closed — a calm, low-arousal afternoon mood.

Try this now
Slow-blink back at her

She's in a trusting state — slow blinks read as feline "I love you".

In Haku's voice

"The warm spot. The good warm spot. I am the warm spot now."

02

Get the reading.

In about ten seconds: their mood, their pain score out of 10, what their body language is saying, what they're meowing about, and one specific thing you can do for them right now.

  • Primary state (50+ labels: from "Content" to "Wants attention")
  • Vet-grade pain score (Feline Grimace Scale, out of 10)
  • Five-axis mood radar + body-language breakdown
  • Inner monologue in your cat's voice — pick from 10 personalities
03

Watch the trends.

After a few readings Haku knows your cat's normal — their typical pain score, mood, trust signals, vocal frequency. When something drifts, you get a heads up. That's the difference between a vet visit and an emergency.

  • 30-day rolling baseline per cat
  • Auto-alerts when metrics deviate meaningfully
  • Spot arthritis, dental pain, kidney issues early
  • One-tap vet-ready PDF report

The science under the hood

Real research. Not vibes.

Haku's brain is built on published feline ethology and clinical pain scoring — not opinions. Five specialist AI analysts each read your video for one thing, then a synthesizer composes the final reading.

Feline Grimace Scale

Évangelista et al. (2019). Five facial action units, validated against opioid response.

UC Davis Cat Stress Score

Kessler & Turner (1997). 1–7 stress estimate from posture + ear/eye state.

Leyhausen T/D matrix

Tension/Defense state model — what your cat's body is saying about intent.

Brown & Bradshaw vocalizations

Acoustic features measured in your browser via Web Audio. Real DSP, not guesses.

WSAVA body condition

Standard 1–9 body-condition score from waist visibility + profile.

Breed calibration

Persian vs Bengal vs Maine Coon — baselines adjusted per breed family.
