Intra-Office Messaging

What's our story? Who are we?

SideNotesIM is created for small-to medium-sized businesses that need a simple and secure office messaging system that does not require the internet or a dedicated server. The first SideNotes program was designed in 2008 and is now continuing to be developed and sold by BlueNote Software, an indie communications developer located in Plano, Texas.

Our software is built on the suggestions that many of our users share with us. Also, if you discover that you need the software to do something that it doesn't (yet!) you can email your feature request to sales (at)
