> Is there a specific use-case you're thinking of?

The OP mentioned a tutoring use case. If you're going to sell this to educational institutions or companies that serve them, at least in the US, then accessibility is important.

I see. Sorry! I got excited and went in founder mode — for a moment I thought you had a problem we could solve for you :)

Thank you for stressing the importance of accessibility. We're really impressed with the quality of the questions so far.
