SparkSlides: Embed a live, interactive website directly inside PowerPoint

I built SparkEmbed because screenshots are a terrible way to demo something that's alive. PowerPoint is still where so many important presentations happen, but the web is where our dashboards, calculators, products, demos, and interactive experiences live. I wanted the two to work together. So SparkEmbed lets you put a live website directly inside a PowerPoint slide. No browser window. No tab switching. No screenshot that becomes outdated five minutes later. You can present a live dashboard, let someone interact with a prototype of your app, demonstrate your product, or walk through a web experience without leaving PowerPoint. It also started with a very practical problem: Microsoft's Web Viewer add-in was retired. I wanted a simple modern replacement that works on both Windows and Mac desktop PowerPoint. SparkEmbed is a tiny tool with one job: make your PowerPoint slides live.
