How is Sideline Standard different to the legal blackline feature in MS Word or traditional comparison software?

If you've ever needed to compare two individual clauses, you'll know the drill. Copy & paste the first clause into a new Word document, copy & paste the second clause into a second new Word document, run a full document comparison and be given the compare in a third new document.

You're under the pump. Sideline Standard saves you precious time by allowing you to quickly check for differences without leaving the window you're working in, and also easily present those compares for example in emails or departures tables.

Will my data be secure?

Yes. We do not view, store or transmit outside of your Microsoft environment any data (including emails) processed through Sideline.

Will Sideline cause Outlook to crash or make Word really slow?

No. Sideline is built on the newer, web-based 'Office Add-ins' platform which means it avoids the instability issues that have plagued traditional 'COM' or 'VSTO' add-ins. There's more detailed information here.

What are the minimum software requirements?

Sideline Standard requires Office 2013 (Windows) or Office 2016 (Mac)or later. Sideline for Outlook requires Microsoft 365 or Office LTSC 2021, in each case connected to Exchange Online.

Can I have a demo?

Definitely. Enter your email here and we'll be in touch within 24 hours. If you can't wait, there's also a free web browser version of Sideline Standard here that you can try.

How can my organisation install Sideline?

Deployment is very straightforward as it's done through Microsoft's well-oiled Office Add-ins environment (Sideline has been built as an 'Office Add-in' rather than an older-style 'COM' or 'VSTO' add-in (see here for more details)). We typically liaise with your IT team to centrally deploy Sideline. If you don't have an IT team, we can help you install Sideline over a video call.
