Acacia

Acacia is a local-first PDF workspace for people who review, organize, annotate, and compare professional documents. Open PDFs into a polished reading surface with thumbnail navigation, page controls, zoom, metadata, comments, and export actions. Keep reports, research, invoices, contracts, and review documents organized with tags, collections, favorites, recent activity, and reading progress. Built for focused document work: - Organize a local PDF library with tags and collections - Continue reading from saved document progress - Review document metadata and quick actions in an inspector - Navigate pages with thumbnail rails and a bottom scrubber - Add local annotations and comments without modifying originals - Export annotated copies, page images, or text - Compare two PDF versions side by side with synced navigation - Work offline with local sidecar metadata Acacia is designed for solo professionals, researchers, operators, and finance or strategy teams who want a quiet, fast document workspace without cloud lock-in. Your original PDF files stay untouched. Local annotations, comments, tags, collections, and progress are stored as sidecar app data, and exports create new copies when you need to share reviewed documents.
