        FAQ

        When is comparing two videos useful?

        Whenever you want to understand how two sources cover the same topic. Common cases: comparing two product reviews before buying, cross-referencing two tutorials to find the best approach, analyzing how different news channels frame the same story, or checking whether two experts agree on the same subject.

        What kinds of videos work best?

        Videos that cover the same or similar topics work best. For example: two reviews of the same product, two lectures on the same subject, two news reports on the same event, or two tutorials teaching the same skill. The tool works with any video that has captions or spoken audio.

        What does the overlap score mean?

        The overlap score (0-100%) measures how much the two videos cover the same ground. A high score means the videos discuss very similar points. A low score means they cover mostly different aspects. It helps you quickly gauge whether the videos are redundant or complementary.

        Can the videos be on different topics?

        You can compare any two videos, but the comparison is most insightful when they cover related topics. If the videos are completely unrelated, the tool will note that there is minimal overlap and list what each video covers independently.

        How long does the comparison take?

        Typically about 20 seconds for two videos. Both videos are processed in parallel, then the AI compares their content. Longer videos may take slightly more time.

        Is it really free?

        100% free, no signup required. You get 10 free comparisons per day. We built this to help researchers, students, and anyone who watches educational content make better sense of multiple sources.
