ZerreA tiny creature
that grows from your real life.
Zerre lives on your desktop. It naps on the Dock, hops onto your windows, chases your cursor, and grows from what you actually do: focus blocks, commits, coding agents, breaks and meetings. Not a dashboard with a mascot. A pet that becomes a little picture of your days.

Alive, calm, and fed by your day
Zerre is Turkish for a mote, a speck. It starts as one, and grows.
It grows with you
A sprout on its head grows with the days you show up and never shrinks. Habits you keep for a week become traits it wears: headphones for deep focus, a rocket badge for shipping, a nightcap for late nights, a bento box for real lunch breaks. When a habit fades, so does the trait. Nothing is lost for good, and nothing punishes you.
It works alongside you
Hooks for Claude Code, Codex, Gemini CLI and OpenCode, git and long terminal commands. When an agent finishes or needs you, Zerre holds up a note and keeps it in its backpack until you look. Click the note to go straight back to that terminal.
Calm by default
At most three gentle nudges a day, never the same one twice in a row, and none during meetings, focus blocks or the night. It gets ready before your meetings and hides at the edge of the screen while they run. Neglect makes it sleepy, never sad.
A lot of tiny life
Dozens of pastimes: juggling, jump rope, a paper plane, a bird on its sprout, tea in the afternoon, fishing off a window's edge, a snowman in winter. Pair two traits and it discovers combos. Pet it, poke it, drag it around. It has opinions.

It notices, it doesn't read
Zerre knows that something happened, never what it was: an agent finished in a folder, a command ran for four minutes, you were busy from two to three. No prompts, no code, no meeting titles, no keystrokes. Everything stays on your Mac, with no accounts, analytics or tracking.
