Tiling in Flow.
Precision without friction.
Drag a window toward an edge and the windows around it make room. You see the result before you let go, and you can take it back after. No hotkey alphabet to memorize.
There's no public build yet. One email when the beta opens — nothing else.

Drag any window toward an edge.
Free until you say otherwise
Flowtile doesn't take over your desktop. It only maintains the relationships you build by hand.
A new window behaves like a new window on macOS: drag it, resize it, stack it over anything. The moment you push one against an edge or onto another window, those two form a relationship. From then on the engine keeps their proportions; drag it back out and it returns to its free size.
You decide the relationship. It handles the arithmetic.
Changes stay inside the group you just touched.
Inside a group, the split is maintained by a BSP engine: a new window splits only the branch it was dropped on, gutters can be dragged to change proportions, and windows outside the group don't move at all. You never have to understand the tree — you only see windows answering your hand.
- Push to an edgeThe primary preview appears first, then the candidates; slide along the edge to pick one, then let go.
- Drop on a tiled windowOnly that branch splits. Drop in the middle and the two windows trade places.
- Drag a gutterThe preview shows the new proportions. On release the whole group scales; nothing outside it moves.
- Drag out 20 ptThe window returns to its saved free size. Its slot stays empty instead of letting the neighbors swell.
It happens in the preview first
What you see is what lands, and every step comes back.
Every layout is on screen before it exists. Release to commit; after that, undo, restore, or tidy the whole group from the menu bar. Scenes and templates remember app roles, display layouts and split ratios — and preview before they restore.

Flowtile
Drag the window where you want it. Let go.
Shortcuts can be recorded if you want them. None are taken by default.
Your habits stay on your Mac
No uploads, no window contents, no screen recording.
Flowtile remembers the layout choices you made: an app identifier and a geometry. It doesn't store window titles, doesn't read what's inside a window, and makes no network calls at all. Settings, scenes and rules are local JSON, written atomically — delete the folder and it's gone.
Accessibility and Input Monitoring, to see dragging and hovering. Both are local and can be revoked in System Settings.
Screen Recording. It doesn't read what you type, and it doesn't use private Spaces APIs.
~/Library/Application Support/Flowtile/ — versioned, atomic. Delete the folder to start clean.
