In simple English
GuiaFlow helps you create step-by-step product walkthroughs and interactive tours. You capture screens of your web app, add highlights, and write descriptions for each step. It is an open-source alternative to paid services like Arcade or Supademo. You can run it for free on your own machine or use your own AI keys for text and voice narration. The software costs nothing to download, though the author offers a paid cloud plan for permanent links and hosted AI.
What it is
An editor and player for interactive product demos built from screenshots, with a companion Chrome extension and a desktop application built with Electron (a framework for building desktop apps using web technologies). It includes support for AI narration, custom themes, lead capture, and multiple export formats including single-file HTML and MP4 video.
