Arcade creates interactive, clickable product demos from screenshots that SaaS companies embed on websites and in sales outreach to showcase features without live access.
About
Arcade is an interactive product demo platform that allows SaaS companies to convert application screenshots into fully clickable, self-guided product tours that prospects can explore without a sales engineer walking them through a live demo or requiring a trial account setup. The platform's capture tool takes a series of screenshots through a browser extension as a presenter navigates the product, and the editing environment adds clickable hotspots, tooltips, and guided step flows to those screenshots, producing a demo that behaves like an interactive walkthrough of the real product without connecting to live backend systems. This approach lets companies showcase polished, stable demo experiences on marketing websites, in email campaigns, and in sales sequences at any stage of the funnel without the environment instability and data sensitivity concerns of live product access.
