## What this tool does
Stitch chat screenshots or tutorial pages into one long image — top to bottom, widths aligned.

## Typical user problems
- Tutorial steps, chat histories and price lists live in a dozen screenshots. Viewers scroll through them out of order — one stitched image is cleaner and impossible to misread.
- Sharing a 12-screenshot conversation as 12 files loses the story. One tall image tells it in order.
