I am a medical student juggling rounds and study. Read & Explain makes dense papers readable on the go with bite sized AI summaries and clarifications. The synchronized highlighting helps me track the argument while listening. Voices are natural and 3x speed fights fatigue. A few medical terms are mispronounced and a couple explanations oversimplify rare topics.

Trusted ReviewerPer response listening makes contract reviews on the move effortless
What I liked
What could be better
I review contracts and client reports while commuting. Per response listening lets me hear AI clarifications as they appear, so I catch red flags without rereading every clause. Multi format support means I move between PDFs Word and emails without exporting. The voices are convincing and playback is fast, but the AI replies can stretch long clauses and language handling is not perfect.
