What Leftover does
Leftover is a free browser-based material reuse planner that starts with what you already own and estimates whether full pieces and usable offcuts can cover a project.
Seven live material checkers
The site includes reuse-first checkers for tile, flooring, plywood, lumber, wallpaper, decking and trim. The tile tool also checks entered scrap dimensions and rotation rather than area alone.
Inventory and saved-batch planning
Save a simple leftover inventory in your browser, discover projects it may cover, calculate a Reuse Score and estimate the purchase gap. No account or photo upload is required.
Planning, not professional advice
Always verify real measurements, material condition, cut layout and manufacturer or installer requirements before cutting or buying.
