This is actually a great use case for something like Windows Recall. Ingestion of data after the fact requires the data to be discoverable.
If there was a way to add a meta-prompt to Windows Recall like "Create a log entry every time I watch something with its title and URL" it could serve as a history whether things were watched on YouTube, Vimeo, or any other site, without requiring plugging into each service individually. Repeat ad nauseum for each thing to be logged, or perhaps someone can come up with a more clever query than I that catches everything sufficiently.
The level of granularity on many services might be surprisingly large, preventing introspection of the data at a useful level.
