Interesting idea. Some feedback - The UI doesn't look very good everywhere (text on the landing page has low contrast, awkward elements placement in the tool)

- Why are you restricting the product only for education? From your demo it seems like it could be used for anything? E.g finding animations, certain video styles Your real product seems to be a semantic search for Youtube

- You should return a list of videos, instead of a single one. Allow people to choose the one they like most

Otherwise, cool project, it's also not something I would pay for, but maybe some people would
