Highlight any text on any page and instantly understand it — in any language. ContextLens turns any text you don't understand into a clear explanation, without leaving the page. Highlight a word, a sentence, or a whole paragraph and instantly get a plain-language explanation. Go further with Deep Dive for a richer breakdown, screenshot any part of the screen to explain text inside images, or use Listen to explain speech from a video or lecture you did not catch. Save anything worth remembering as a flashcard and review it with built-in spaced repetition. WHAT YOU CAN DO • Highlight to understand: select text on any page and get an instant explanation. • Deep Dive: a deeper, more thorough explanation when you want to really get it. • Screenshot to explain: capture any region, even text inside images, and have it explained. • Listen: explain what was just said in a video or lecture, in the language you are learning. • Visualize: tap Image and get a labeled picture of the idea, for things words don't capture. • Save and review: turn captures into flashcards and remember them with spaced repetition. GREAT FOR LANGUAGE LEARNERS ContextLens has first-class support for Arabic and right-to-left text, ideal for reading the Quran, Arabic news, and classical texts, with explanations that respect the original script. It works on any language, so it's just as useful for studying, research, and reading anything unfamiliar. HOW IT WORKS Highlight text, use the screenshot shortcut, or start Listen, and ContextLens explains it right where you are. Create a free account to save your captures and sync your flashcards across devices. PRIVACY The text, screenshot, or audio segment you choose is sent to our servers and to AI providers only to generate your explanation. Listen never uses your microphone and only reads audio the tab is already playing. We never sell your data. We also collect anonymous usage analytics, which features get used and never page content, to improve the product.
