Clear the lawn and start again
Run a new detection
Tap the edge of your lawn nearest the road.
Drag it to move it. To extend a whole edge
instead, tap the line between two corners.

Extend to the road
Press Line on the map to move the boundary, or a
corner of it. Everything measured is trimmed to this line.

Count grass under trees
Canopy hides lawn that is really there. Small
gaps inside your lawn are counted as grass; big ones (a pool, a
shed) are not.

A corner dragged past the lawn is held at its edge, and the
brush will not paint beyond it. Only affects what you draw or
move while this is on.

Lets the brush and the corner tools go past your boundary.
Off, a corner dragged past it is held at the line. Turning it back
off trims everything to the line again — your detected lawn is kept,
not re-run.
How to correct the shape
The buttons down the right of the map choose what you are
editing . Only that thing responds to a touch, so correcting a
lawn outline can no longer move the property line by accident.
Line edits the property boundary: tap a line to slide that
whole edge out to the road, or a corner to move, add or delete it.Layers , on the left of the map, switches between
photographs of the same ground taken in different years and
different light. Only the sources marked as measurable can be sent
to the AI; the rest are there to look at, and detection quietly
falls back to Mapbox for those. If shadows or leaf cover are hiding
your lawn, try another picture and detect again.Lawn edits the measured shape, with three tools:
Points to drag corners, Add to paint lawn in, and
Erase to rub out anything that is not lawn — a driveway the
AI grabbed, a flower bed, a neighbour's grass. The outline redraws
itself around what is left.Add works on an empty map too, so you can paint a lawn from
scratch instead of placing corners.Tapping a line wins over tapping a corner, so extending stays the
easy gesture — aim right at a dot when you want the point itself.
Move is the only mode where a whole shape can be dragged.
Everywhere else shapes are locked, so a stray touch with a brush
cannot slide your lawn across the map.Trim or extend the edge pulls the detected outline in or
pushes it out by up to three feet, all the way round. It re-reads
the detection you already paid for, so it costs nothing and runs no
new detection. Pulling in is the quickest way to shed thin slivers
the AI ran along a driveway or a fence.Undo is on the map as well as below it, since that is
where you are looking when something goes wrong.Delete selected removes a shape you don't mow.Draw it myself adds another patch — areas add up.Yellow dots are corners taken straight from the county map.
The AI finds grass inside your property line only — the
neighbours' lawn is trimmed off automatically.

Measurements come from satellite imagery and public
county records. Treat them as a close estimate, not a survey.
