A flashcard app looks the same in almost every screenshot, a card, a flip, another card. That similarity is exactly why a demo video needs to show something a screenshot cannot: the grading step. Every flashcard app that claims to be more than a paper stack does something with the answer, whether that is scheduling a harder review sooner or simply tracking accuracy. A video that only shows cards flipping proves nothing a static image could not already prove.
GogoScreen takes a URL and one line about what to show, then returns a narrated, edited MP4 with click zooms, cursor smoothing, dead air cuts, and captions. It can use a demo account for a route that needs a login. It has no way to know which part of a study session is the meaningful one, so the flow hint has to name the grading moment explicitly rather than describing "studying" in general terms.
