Sidenote

Sidenote is a browser extension that lets teams add contextual notes and documentation directly onto web pages. Instead of keeping information in separate documents or wikis, you can attach notes to the specific websites and tools where they're needed. This means your team can access relevant documentation without switching between tabs or applications, keeping everything in the context where it will be used.

The tool works as a sidebar in your browser where you can create, view, and organize notes. You can build step-by-step guides for onboarding new team members, document processes for specific tools, or capture research findings as you browse. What makes Sidenote stand out is its contextual approach—notes are tied to specific URLs, so your team automatically sees relevant information when visiting those pages.

Product teams, engineering teams, and customer success departments benefit most from Sidenote. It's particularly useful for creating onboarding documentation that new hires can follow along with in real-time, tracking user research and feedback on specific product pages, and sharing competitor analysis directly on competitor websites. The tool helps teams build a living knowledge base that grows organically as team members contribute insights in context.
