Compare attachment versions side-by-side

With a list of other versions just a click away, you can make sure you're not working on an outdated version.

Renaming files to indicate versions works great. DokDok will highlight version numbers, dates, initials or keywords such as "draft" and "final" in the file name.

To get a quick summary of what's been changed in the attachment you just received, click the "changes in document" tab. DokDok will list insertions and deletions between any two given versions with a button to compare both versions side-by-side (currently supports Microsoft Word and OpenOffice.org files).

Automatic document archive

Forget about keeping file sharing sites up-to-date or setting up folder synching. DokDok uses documents already found in your email.

From any given message, you can quickly get a list of related files as well as other document exchanged with the sender and recipients. No more time lost searching for attachments.

You can also preview attachments in your web browser. No need to download the file or install special software.

The DokDok API is now Context.IO

Our Email API turns mailboxes into a data source developers can use to integrate email data in their applications.

Given that this API is about way more than just attachments, we figured that "DokDok API" was a name that didn't do it justice ... welcome to Context.IO.
