Most AI tools answer one question and stop. ClickNote is built around how people actually learn. Highlight any confusing line on a webpage or PDF and get an instant explanation that reads the page around it. Still unclear? Select inside the answer to go deeper, or ask a follow-up, without leaving the page or breaking your flow. Made for dense docs, research papers and textbooks.
