With its hierarchical group structure, organization, and navigation functions, as well as its advanced text editing capabilities and full screen mode, DEVONthink is perfectly suited for writing many kinds of documents, from notes to whole books.

Create new documents with just one click, find related documents in your database, and connect them with Wiki-style or static cross-links. Working these documents in your databases, you can switch from one document to another with just one click, and manage even large projects with ease.

Utilize markers, like flags or color labels to help visually distinguish items, by importance or other criteria using label names. And similar to the Finder, you can create groups, as deeply (or shallowly) nested as you'd like.
