Crafted scan workspace

Turn a noisy phone photo or a whole batch into crisp, searchable sheets.

ClearSheet detects the page, straightens perspective, auto-corrects small post-warp tilt, renders scan profiles, and exports OCR-backed PDFs from a single review surface.

Quadrilateral detection with auto-rotation correction after the warp.

Scan Modes

3 profiles

Switch between clean, balanced, and OCR-optimized rendering.

Batch Flow

Queue & review

Process multiple uploads and inspect each result in one workspace.

Workflow board

Live frontend preview
