Less describing.
More understanding.
Select a sentence, a diagram, a handwritten line, or one of your own circles. Your question travels with the part you mean.
Circle the second line of your attempt, then ask why it works. The selected circle and the work beneath it become part of the next turn.
A question with a place on the page
Point & Ask sends the selected canonical region, selected annotation IDs, and a current composite crop to the tutor. Your later ink is included, so the conversation can follow your attempt.
A closer look when it matters
The tutor can inspect a region or retrieve another indexed page. Being indexed is different from having been visually inspected in the current turn. When two regions are plausible, the tutor should ask which one you mean.
Keep uncertainty visible
Handwriting and diagrams can be ambiguous. The tutor should ask for a clearer view or confirmation rather than silently choosing a symbol. You can upload a clearer image as an additional document.
