DEVONthink Pro Office/Server 3.9.1 portable for macOS is DEVONtechnologies’ document and information management solution. It supports a large variety of file formats and stores them in a database enhanced by artificial intelligence (AI). Many document formats can be directly viewed, edited, and annotated. A powerful search language finds documents in an instant, smart groups keep them always at hand.

Smart groups present related data based on saved searches, and reminders make sure you’ll not forget to work on your evil genius master plan. Add interesting materials to the reading list.
Collect, analyze, summarize, write: View all your data in one place, use tags to quickly organize documents, and write in editors optimized for plain text, rich text, and Markdown. Smart templates are a great starting point for new documents.
Insert manual or automatic cross-references, add annotations to any documents, and enrich your data with custom metadata. Imprint PDFs and images with customizable stamps and add Bates Numbers to them. Two full-screen modes help you stay focused.
Store your documents in self-contained databases or just add references to external files. Encrypt databases for maximum privacy. Clip data from other apps with a keystroke or write notes and add them to the inbox to file them later. With its many extensions, DEVONthink easily integrates into your workflow.
Add links to your documents to all apps that take web addresses, e.g. OmniFocus or Apple Mail, or export your documents in their original file formats. Give your co-workers access with the built-in web interface (Server edition only). DEVONthink never holds your data hostage.
Use your databases on all your Macs, iPads, and iPhones by synchronizing them between your devices. You decide what data is synced, when, and where. Strong encryption makes sure that your data belongs to you, not to your service provider or us.
Have your important documents with you all the time with DEVONthink To Go. Designed as a standalone app it allows you to not only view but also works with your data while you’re away from your Mac. Organize your documents, add notes, annotate PDFs or clip data from the web. Use the fast search and predefined smart groups to quickly find what you need.
