1 Grid & images
Click a cell to pick a file, drop an image on it, or focus a cell and press Ctrl+V to paste from the clipboard. All tiles must share the same dimensions (screenshots from one device).
2 Work area & exclusions
Drag on the reference tile. Work area: one rectangle, applied to every tile (crops fixed UI chrome). Exclusion: floating elements inside the work area — ignored when matching, and replaced with another tile's content where an overlapping tile covers the same spot. Scroll to zoom, drag in Pan mode (or hold Space) to pan; zoom in for pixel-accurate edges.
3 Stitch
Data & privacy
Image data is processed entirely in this tab and is never uploaded. Requilt sends one metadata-only event per stitch — numbers, flags and timings, never pixels and never filenames. Below is the exact object that would be sent, rendered from the same code path that sends it.
