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. FREE TO USE DraftPlanar's viewer is completely free — unlimited PDF, Markdown, and canvas imports with full 60 FPS hardware-accelerated rendering. No limits, no watermarks. Start viewing immediately.
