Google has announced an AI service they call Project Tailwind, which seems to have great promise for learning. The service allows a user to interact with documents you upload or have stored in Google Docs. The link above does not provide access but allows you to get your name on a waitlist. It is unclear how long until the service is generally available, but those focused on ed tech will likely want to obtain early access to develop their personal understanding of the tool.
There are existing ways to engage with content you designate and I have written about how to use such tools for tutoring. Google would provide advantages in the integration of its tool with other tools already used in classrooms.
