Zerre moved into your notch.
A tiny creature for your Mac that notices agent handoffs and commits. Now it does focus blocks with you: it hops up into the notch to work at its own little desk, keeps interruptions waiting, and grows a tomato for every block you finish.

That’s Zerre, down at the bottom of this window. Say hi.
You work. It works beside you.
Set your blocks and breaks once in Settings. Then every block goes like this. Watch the notch at the top of this page: it’s counting down while you read.

It hops up into your notch.
When a block starts, Zerre crouches and leaps up past the menu bar. A smaller Zerre, drawn for the notch, drops into its room up there.

It works at its own little desk.
Eyes on its laptop, one paw tapping at a time, a glance up now and then. The vine flowers while the block runs. In the app, tap the desk for your inbox and the vine for the shelf.

Everything else goes soft.
Windows behind the one you’re in blur and dim, so your work is the only loud thing on screen. Drop Zerre onto a window to focus right there. You choose how much blur and darkness in Settings, and you can lift it for a block. You’re seeing it on this page right now.

Interruptions wait in its backpack.
Your agents can finish and your commands can complete. Zerre tucks their notes into its backpack and unpacks them when the block is over. Only what can’t wait, a reminder or an agent stuck on you, still gets through.

Every block grows a tomato.
Finish a block and a tomato ripens on the vine. Stop early and it still grows a green one, because it still counts. Then a short recap of the block: what happened, and if you want it, which apps the time went to. App names and minutes, nothing more.
Flowering: a block is running.

Day’s end
Your days fill a shelf.
Tap the vine and a shelf opens below the notch. Each day with a finished block gets a jar of its tomatoes, lidded when the day is over. Older weeks become a single bottle of sauce. Days without a block add nothing, so there are no gaps to count.
An example week
Your habits grow traits. Each one arrives in style.
A trophy for a 50-minute block, a nightcap for late nights, a hard hat for long builds. Traits come from the shape of your days and stay once earned. The first time each one appears, Zerre gets a little scene of its own, then a note saying what you did.
Six are shown here. Pick one to watch it. The rest keep their secret until your days reveal them.

A companion that knows when to hush.
Zerre has a small daily nudge budget. It stays quiet during focus blocks, at night, and during meetings when you connect Calendar. Breaks are its turn too: tea for a short one, a nap for a long one, whether or not you take yours. Ignore it for a while and it gets sleepy, never punishing.
See exactly what it notices
It notices that things happened. It does not read your work.
Agent hooks tell Zerre about handoffs, not prompts or code. Calendar access, if you grant it, tells Zerre when you’re busy, not what the meeting is. Time per app during a block is app names and minutes, and you can turn it off. Its history stays on your Mac. The app has no account or usage telemetry. This website counts visits and a few clicks; the details are on the privacy page.
Notes you choose to write on Zerre’s board are saved locally so it can show them again.

Zerre for Mac is free. Download it, start a block, and see what grows beside you.
