Add an item via Check Tiplines

Users can add any supported items via Check Tiplines.

Supported media types

Check supports 4 types of media types that can be added onto your workspace either manually, using the browser extension, or Tiplines.


Links are used to capture social media posts, web articles, images, and videos that are hosted online. As long as the file is public, the social media post and associated media files will be displayed in Check.


Text items are text-based entries. If you are receiving items via a Check tipline, an item will be of the type 'text' only if no image, video or link is associated with it.

In the analysis panel, text claims will be displayed the same as how submitted links generate titles and content.

If a blank item is submitted to the Tipline, it will not be displayed but will be stored in the database. Similarly, Tipline submissions that contain only numbers and no useful information will not be visible but will be stored in the database.
