ContextSnap — Screenshot & Ask AI

Like a dictionary, but for whole ideas: highlight a hard sentence or snap a figure, get a short answer in your language. No prompt.

Still reading the same sentence three times? ContextSnap is like a dictionary, but for whole ideas. Highlight the sentence, equation or figure you are stuck on, and a short, clear explanation appears right on the page, in your own language, and your highlight stays put. No prompt to write, no account to create. YOU HAVE ALREADY TRIED EVERYTHING • A translator gives you your language, but not the meaning. • A chatbot gives great answers, if you write the prompt again every time. Then you read an essay to find one sentence. • AI in your browser can see the page, but still waits for your prompt, then answers in a chat off to the side. ContextSnap was made for one moment: you are stuck on one sentence, and you just want to understand it and keep reading. HOW IT WORKS • Highlight a sentence and click Explain (or press Alt+Q, Option+Q on Mac). ContextSnap reads the paragraph around it, so the answer fits what you are reading. • Snap a region (Alt+Z): a figure, table, chart or equation, even when it is not text. • Snap the context, then the question (Alt+Shift+Z): capture the whole figure first, then the one panel or symbol you want explained. • A short answer comes first. One tap for "Simpler", "Example" or "More detail", or ask a follow-up in the same panel. • Set your answer language once: 20 languages, or follow Chrome's language. Technical terms keep the original word next to the translation, so you learn the vocabulary as you read. MADE FOR • Researchers and graduate students working through papers and Methods sections. • International students reading in their second language. • Anyone reading a contract or a manual they cannot afford to misread. Not a summarizer: summaries are great for deciding what to read. ContextSnap is for when you read the original, sentence by sentence. WHERE IT WORKS Web pages, including the HTML versions of papers on PubMed Central, arXiv, bioRxiv and most journal sites.

PRIVACY Only the text you select or the region you snap is sent, and only when you ask. We never receive the page address, your browsing history or other tabs. Our server stores nothing you send. Explanations are generated through our server by OpenAI (GPT-6 Luna) or Google Gemini, under paid API terms that do not allow your content to be used for training, so your unpublished drafts stay yours.
