ClickNote

Select the confusing part and ClickNote explains it instantly with context, right where you are — on web pages and now in PDFs too. Unlike a dictionary or a chatbot, ClickNote reads the document with you. It uses the surrounding paragraphs, the section you are in, and what you have already read, so the explanation fits the exact context instead of giving you a generic definition. HOW IT WORKS Select any text on any webpage or in a PDF An explanation appears next to your selection in seconds Still confused? Select any phrase inside the answer to go deeper, or type a follow-up question NEW: PDFS, EXPLAINED TOO ClickNote now works for pdf's too: select a passage and the explanation appears in place. The PDF itself never leaves your device. It is rendered entirely locally. (PDF support needs Chrome 151 or newer; on older versions everything else keeps working.) WHY PEOPLE KEEP IT Works everywhere: documentation, research papers, PDFs, technical blogs, news, Wikipedia Answers stream in fast and stay short, so you never lose reading flow Go-deeper chains: every answer is selectable, letting you drill down until it clicks Quick pause: press left and right mouse buttons together to pause ClickNote, click the toolbar icon to bring it back Light and dark theme, draggable and resizable panel PRIVATE BY DESIGN Nothing is read or sent until you select text and ask. Pages where you never request an explanation are never touched. PDFs are rendered on your device and never uploaded. Explanations are generated on demand and never stored on our servers. Sign in with Google, GitHub, or email and start explaining. Free plan included, no card required
