A review walkthrough exists to answer one question for one specific person: did this Base44 build do the thing that was asked for. That is a narrower job than a general demo video, and it should be treated that way. A reviewer checking completed work does not need to be sold on the product. They need to be able to confirm, quickly and without ambiguity, that a stated requirement was met.
GogoScreen produces this kind of video from a web app URL and a one line hint about what to show, returning a narrated, edited MP4 with click zooms, cursor smoothing, dead air removed, and captions burned in. A demo account can be used for any part of the flow that sits behind a login, which is common for a Base44 build since account handling is frequently part of what the generator sets up. None of this guarantees a first render will be review ready. Leave time to check the candidate against the original request before sending it.
