What does Sideline do?

Sideline is an add-in to Outlook* designed for high-performing law firms.

  • Editing a colleague's draft email? Sideline automatically converts edits from clean into redlined text.
  • Your colleague made edits in clean and then sent it out or back to you? Sideline shows you the changes with a single click.
  • Received your email back with edits shown in redline? Sideline lets you accept or reject each change.

Is Sideline secure and stable?


We do not store any data (including emails) processed through Sideline. Sideline is hosted on Microsoft Azure and SSL-secured to protect data in transit.
