New windows find their spot
A new window lands in free space, or Kempt makes room for it, at the size you usually give that app. It never squeezes a window you're using into a strip.
A window manager for macOS
Your Mac's windows,
on autopilot.
Kempt arranges your Mac's windows for you. New windows find their spot, closed ones leave no gaps, and every screen stays tidy without you dragging a thing.

Free for 7 days, then $14.99 once. No subscription. For macOS 14 or later.
Your Mac, mid-afternoon. Safari and Notes, side by side.
Autopilot
Every window in its place. All day.
Kempt reads the free space on your screens and decides where each window goes, the moment it opens and the moment another one closes.
Closed windows leave no holes
Close a window or quit an app, and the windows next to it grow into the space.
Gaps close on their own
Slivers of empty space between windows are filled by the neighbour that lines up with them.
Room on every screen
When a screen is full, a new window goes to one with more room, or the windows you use least stack neatly, each one click away.
Monitors come and go
Undock, and macOS shuffles your windows. Plug the monitor back in, and Kempt puts just those windows back where they were.
Appears once, in place
A new window shows up already in its spot, with a soft flash so your eye finds it. No watching it jump around.
Take the wheel
When you want to drive, it follows your lead.
Drag, drop and resize the way you already do. Kempt finishes the job, with a live preview of where the window will land.
Drag to fill
Drag a window over empty space and let go. It fills that space exactly, stopping at the windows around it.
Drop to split
Drop a window onto another and it takes a third near the edge, or half toward the middle. The other keeps the rest.
⇧ Shift to swap
Hold Shift as you drop one window on another, and they trade places and sizes, even across displays.
⌘ Command to stack
Hold ⌘ as you drop, and the windows share one spot, cascaded so each shows an edge. Click one and it comes forward right where it is.
Resize into neighbours
Drag an edge into the window next to it. That window makes room, keeping its far edge, so nothing ends up covered.
Tidy every screen
One click spreads windows across all your displays, tiles each screen, and stacks whatever won't fit instead of leaving it overlapping.
Also in the menu: merge an app's windows into tabs in one window, in Safari, Finder and other apps with tabs.
Learns how you work
It learns your habits. It asks before making rules.
- Remembers your sizes and places. The size you give each app, and where you put it, for each monitor setup.
- Suggests, never assumes. After a few consistent placements it asks whether to make that a rule. It never makes one on its own.
- Gives space to what you use. Time in front, clicks and scrolls tell it which windows matter, so they get the room. It counts; it never reads.
- Knows each app's limits. It learns how small an app's windows really go, so it never tries a size the app won't take.
Thoughtful by design
You're always in control.
- Lock what shouldn't move. Locked apps are never moved or resized automatically. Lock a single window until it closes.
- Undo anything. Every automatic change can be undone, and Kempt learns from it.
- Hands off what you just touched. A window you moved in the last two minutes is left alone.
- Checked after it lands. If an app refuses its new size and would cover another window, Kempt puts things back and remembers why.
- A switch for everything. Turn off any behaviour, or pause all automation, from the menu bar. No Dock icon, no clutter.

Questions
What does Kempt need access to?
The Accessibility permission, which macOS requires for any app that moves other apps' windows. Kempt asks for it on first launch: System Settings → Privacy & Security → Accessibility. It doesn't use Screen Recording.
Will it move a window I just put somewhere?
No. A window you moved in the last two minutes is left alone, locked apps are never moved automatically, and every automatic change can be undone from the menu.
Does it work with more than one display?
Yes. A new window can go to a screen with more room, Tidy arranges every screen at once, and when you plug a monitor back in, the windows macOS moved off it go back.
What about Spaces and full-screen apps?
Kempt arranges the windows on the Space you're using. Full-screen windows are left alone.
How does the free trial work?
Start the 7-day trial from Kempt's menu to use every feature, with nothing charged. Afterwards, unlock Kempt with a one-time purchase. If you don't, Kempt simply stops arranging windows; nothing it already arranged is undone. The trial follows your Apple ID, so reinstalling doesn't restart it.
Can I use it on more than one Mac?
Yes. On another Mac signed in with the same Apple ID, choose Restore Purchases in Kempt's menu.
Does Kempt collect any data?
No. It has no account, no servers and no analytics. Everything it learns stays on your Mac. Read the privacy policy.
Stop arranging windows.
Let Kempt keep every screen tidy, so you can get on with your work.
