Create detailed annotations as Markdown or RTF, firmly linked to the document. Use annotations for extensive notes and comments on your document. Write a summary or let a chat model do it for you.

Use unique URLs (item links) to link to documents, groups, and databases in DEVONthink. Reference other documents within DEVONthink or even a specific location in your document. Link your knowledge. Item links also work in any other app that supports URLs, e.g. Apple Calendar. Simply attach a link to a document to an appointment or task.

WikiLinks turn your database into a dynamic network of linked information. They connect documents to other documents, creating your own personal wiki. When needed, you can even export your wiki as a standalone website to share it.

Add the WikiLinks yourself or have DEVONthink create them automatically as soon as you enter the name of another document. The reference takes you directly to the linked object. WikiLinks are perfectly suited for work styles such as the Zettelkasten method.

Define your own metadata for your documents and choose from various data types from text or numbers to yes/no values, item links, or country or language identifiers.

Store all the additional information you need — publication information for a scientific paper, the language of an article, or the total of an invoice. Assign custom metadata manually or via automations, search for it, or use it in smart groups or rules.
