a tiny typewriter
Its own paws tap the keys, the paper fills line by line, and the carriage slides home with a ding.
Katto sits with you while you work. It keeps your day, your focus and your files in order, calms things down when it's all too much, and does zoomies when your AI helpers finish.

Recorded straight from the app. Every coat, every cat.

Its own paws tap the keys, the paper fills line by line, and the carriage slides home with a ding.

Type fast and its tail poofs, its eyes go big, and gold sparkles gather. Afterwards: a slow blink, maybe a sip of water.

Scroll down and it rolls away, unwinding. Scroll up and it rewinds. The companion bats it back.

Paws dangling, it swings with you and lands on its feet. Shake it, and it's dizzy for a moment.

Reach out, lean forward, roll your shoulders, one deep breath. It shows you, one step at a time.

A wiggle, a lap around its friend, a skid and a proud sit. Long jobs get two laps.
Click the cat, and your day opens up.

Built so the app asks less of you on hard days, never more.
Katto listens to the coding agents on your computer and tells you, gently, what they're up to.
Katto opens its door a few people at a time. Write a little note, roll it up, and throw it into the sea.
psst… tap the water.
When the tide brings it in, we'll write back with the key to your chest. Keep an eye on your inbox.
