This is a horrible use case for Windows Recall. Even if we ignore all the privacy implications of having a third party screenshot you every 30 seconds and making the files world readable, it's a bad idea.

Recall has lost a ton of useful metadata you already have - both URL visits and streaming are clearly discernible actions, both at the network stack level, and from your browser history. Throwing that away to trust an LLM to re-infer the same data is both reducing data fidelity and significantly increasing processing cost.

If you want to see this done reasonably well, I'd suggest looking at e.g https://beepb00p.xyz/promnesia.html (which not surprisingly bears a strong similarity to what the article discusses)

LLMs don't add much value here, outside of tightly locked down systems where screenshots are the only way of exporting.
