Drawboard PDF + Notes 6.91.6.0

Drawboard PDF is a document markup and editing application designed for technical and professional workflows. It emphasizes pen-style inking, precise annotation, and tools suited to architects, engineers, legal professionals, educators and students who need to review, measure and collaborate on PDFs.

• Store+Share: cloud-backed annotations with near real-time synchronization for team review.
• Document Builder: merge, reorder and arrange PDFs within the app.
• Measurement tools: calibrate drawings to scale and add linear and area measurements.
• Grids and line templates: selectable layouts to support sketching and note-taking.
• Text export: save text-based annotations as .txt or .csv for downstream review.
• Hyperlinks: link text to web pages, PDF pages or other document locations.
• Digital protractor: measure and rule ink at precise angles; integrates with Surface Dial.
• Engineering line styles and color picker: customize line types (dashed, dotted) and annotation colors.
• Callouts and annotation tools: highlight items needing attention; support for signing and eSigning PDFs.
• Forms and ink: fill PDF forms and add handwritten input.

The interface centers on pen and touch input, aiming for low-friction markup and review. Cloud sync and collaboration features are geared toward multi-user workflows, while precision tools (measurements, protractor, engineering line styles) suit CAD-adjacent tasks. Support for signatures and form ink makes the app usable for approvals and field notes.

Advanced tools are offered through subscription tiers (Pro Lite, Pro Plus, Pro Unlimited), each unlocking different feature sets. A seven-day trial is available; on Windows the trial requires payment details but does not charge until the trial ends, and subscriptions are managed through the Microsoft account. When a trial or subscription ends, the app reverts to the free version: existing annotations and documents remain accessible, but Pro-only features and new uploads are restricted. Subscriptions recur until cancelled via the Microsoft account.

Volume and enterprise licensing options are available from the vendor for larger teams and deployments.
