SoLoDraw

Review PDFs with precise tools while keeping your documents local by default.

SoLoDraw gives you a practical PDF workspace for markup, measurement, page organization, issue tracking, and review. Open a PDF, add clear annotations, and export the finished result without creating an account or uploading the source document.

Key capabilities:
• Draw with pen, highlighter, lines, arrows, shapes, revision clouds, text, callouts, stamps, and numbered markers
• Calibrate and capture distance, area, perimeter, polygon, connected, and angle measurements
• Organize pages, layers, marks, saved views, and project packs
• Track review issues, priorities, assignments, comments, and approval cycles
• Search document text and check compatibility before sharing
• Export a finished PDF or a portable workspace backup

Local-first by design:
Your PDF bytes, markups, thumbnails, OCR results, signatures, and workspace state stay on your device by default. Local editing does not require an account.

Optional encrypted continuity:
When you choose cloud continuity, SoLoDraw encrypts document content on your device before upload. Account sign-in, encrypted sync, cross-device continuity, and shared review are optional.

SoLoDraw is built for focused, professional PDF review without forcing every document into the cloud.
