Everything old documents need

From automated corrections to manual fine-tuning, every tool built for the unique challenges of digitizing aged and damaged pages.

📐

Page Deskew

Automatically detect and correct page rotation from scanning with precision confidence scoring.

💡

Lighting Correction

Remove uneven illumination, shadows, and scanner gradients for perfectly balanced page brightness.

📖

Curvature Correction

Flatten curved pages from book spines with intelligent per-paragraph dewarping for perfect results.

〰️

Line Straightening

Straighten wavy text lines seamlessly — multi-column aware with no visible artifacts.

🩹

Patch Healing

Intelligently fill damaged areas, creases, and stains by reconstructing from surrounding content.

✂️

Smart Crop & Split

Auto-crop to text boundaries, manual crop, multi-region extraction, and two-page spread splitting.

🖨️

Print-Ready Output

Set DPI, page size (A4/A3/Letter), margins, and color mode. Export publication-ready files instantly.

Batch Processing

Process entire directories in parallel. Smart caching ensures identical settings are never recomputed.

Three steps to perfect pages

Upload your scans, let the AI pipeline do the heavy lifting, then fine-tune with professional editing tools.

01

Upload Your Scans

Drop single images or entire batches. Supports JPG, PNG, TIFF, BMP, and WebP up to 500 MB per file.

02

AI Corrects Everything

The pipeline automatically deskews, dewarps, fixes lighting, straightens lines, sharpens text, and cleans edges — all at once.

03

Refine & Export

Use manual tools for precision edits. Set DPI, page size, and margins. Export print-ready files in any format.

Warped, shadowed, and skewed scans become clean, straight, publication-ready documents.
