Use Annotations
Create detailed annotations as Markdown, 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.
Search Your Texts
Scan letters, invoices, documents using your iPad’s or iPhone’s built-in camera. Rotate and deskew the pages and choose whether you want to save them in color, greyscale, or black-and-white. Then convert them to searchable PDFs via text recognition (OCR).
The integrated text recognition is based on Tesseract.

Save Versions
Manually save a version of a document when you’ve reached an important stage or let DEVONthink To Go automatically save versions when you edit them in the app. Specify how many versions DEVONthink To Go should keep and when it should delete older versions. Go back to a previous version at any time.
Define Your Own Metadata
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. Search for custom metadata or use it in smart groups.
Use Item Links
Use unique URLs (item links) to link to documents, groups, and databases in DEVONthink To Go. Reference other documents within DEVONthink To Go 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. Item links created with DEVONthink To Go also work in DEVONthink for Mac and vice versa.
Build Your Own Wiki
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 To Go 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.
