DraftPlanar: PDF Plan Viewer

Metal-accelerated PDF viewer for iPad, iPhone, and Mac. Open massive blueprints instantly, measure to scale, and annotate offline with 60 FPS performance.

DraftPlanar is a hardware-accelerated PDF viewer and markup tool for iPad, iPhone, and Mac. Open large documents — blueprints, floor plans, technical drawings, or any PDF — and view them side by side on an infinite canvas with 60 FPS Metal-native performance.

Unlike single-page PDF readers, DraftPlanar lets you lay out multiple documents at once. Place a floor plan next to a section detail. Compare two versions of a drawing. Pin reference images alongside your specs. Work the way professionals do — with everything visible, not buried in tabs.

WHAT YOU CAN DO

• View & Navigate Large PDFs Open 500+ page documents and zoom in at 60 FPS. Our Metal-native rendering pipeline keeps massive PDFs razor-sharp at any scale. Smooth panning and pinch-to-zoom, optimized for Apple Pencil and trackpad.

• Measure & Dimension Calibrate your drawings to real-world scale. The Precision Measure tool snaps to path vertices, midpoints, and edges in the PDF's vector geometry — accurate to the line.

• Annotate with Apple Pencil Draw, sketch, and redline with a GPU-accelerated pen tool that produces smooth, variable-width strokes. Non-destructive layers keep your annotations separate from the original document. Includes shapes, lasso selection, and a precision eraser.

• Pin Notes & Bookmark Viewports Place visual Pins with rich notes, screenshots, or images directly on document coordinates. Save precise viewports to instantly teleport between distant sections of a large blueprint — perfect for construction punchlists and reading notes.

• Search Text with Fuzzy Matching Find details instantly across hundreds of plans. DraftPlanar's spatial OCR engine reconstructs text layout from raw characters and scanned documents, then runs lightning-fast fuzzy searches — locate labels, dimensions, or notes even with partial matches.

• Compare Document Versions Place two revisions side by side and spot differences. Perfect for reviewing plan updates, spec changes, or contractor submissions.

• Control PDF Layers (OCG) Toggle individual layers in complex PDFs — electrical, plumbing, HVAC, or structural overlays. Filter and search layer names (supports regex) to isolate exactly what you need.

• Import Markdown & Structured Content Drop Markdown files, Mermaid diagrams, Graphviz graphs, images, SVGs, or HTML onto your canvas. Everything renders as crisp, interactive vector objects automatically.
