See It On Your House

Trace a loop around the new area with your finger — it auto-fills as a solid magenta highlight, and doesn't need to be perfectly closed. Works for extending an existing driveway, adding a brand-new patio on plain grass or dirt with no pad there at all, or any other space — the AI is told to replace whatever's under the highlight (grass, dirt, gravel, old pavement) with the new surface. Magenta was tested head-to-head against amber and performed more reliably, since it can't be confused with any real material or object in a photo. This version sends only the one marked-up photo (not a second clean copy). You can draw more than one shape; tap Clear Drawing to start over.
