Why Sideline

Working in the legal industry, we created Sideline after learning we weren't alone juggling multiple windows, scrolling endlessly to find the right comparison files, and fighting expensive, clunky compare software just to do simple text compares.

Some people even told us they had given up and now compared documents by eye, delegated to assistants or didn't even bother checking for differences 😮.

  • Sideline offers a simple solution.

  • Zero training. No bloated features. Lives where you already work.

  • Save time and frustration. No getting lost between multiple files, windows and apps.

  • Fully secure. We don't see or touch your data.
