PDF Markup & Compare

Mark Up Plans. Compare Every Revision.

A complete markup toolset and side-by-side revision compare on a fast, native Windows app, with added and removed changes highlighted.

Markup, compare, and export are included on every plan.

A Complete Markup & Review Workflow

Annotate sheets, track exactly what changed between revisions, and hand off clean, flattened PDFs.

Full Markup Toolset

Lines, shapes, clouds, callouts, dimensions, and text. All 19 markup types get independent stroke, fill, and font color.

Stamps & Signatures

Drawn, image, or typed signatures and reusable stamps to review, approve, and issue sheets.

Revision Compare & Overlay

Blend two versions of a sheet with a scrubber: crossfade, onion-skin, or snap between them.

Difference Highlighting

Added content in green, removed in magenta. Pixel-level difference highlighting between revisions, with editable colors.

OCR Text Search

Find any note, callout, or detail across every sheet in the set with Windows-native OCR.

Office Add-in & PDF Export

Create a PDF from Word, Excel, or PowerPoint, and export flattened, annotated PDFs in one click.
