Sidenote
Sidenote is a team productivity browser extension that pins onboarding notes and internal documentation to the exact web pages your team uses every day. You capture step-by-step guides, API notes, and troubleshooting tips in context so new hires follow instructions while they work in Chrome.
Traditional wikis sit in a separate tab, so engineers and CS reps constantly context-switch to hunt for the right doc. Sidenote attaches knowledge to live URLs inside the browser, which keeps onboarding walkthroughs and debugging notes visible where the work happens instead of buried in a shared folder.
Engineering, sales, customer success, HR, product, and marketing teams use Sidenote to document internal tools, share research while browsing, and build a growing knowledge base. The site offers free signup at sidenoteapp.com/signup plus Calendly demo booking for teams that need a guided rollout.
