Description
Understand anything you highlight — explanations, fact-checks and voice control, no account, no setup Stop opening a new tab just to understand one sentence. Highlight anything on any page and JustClarify explains it right there, reading the text around it so you get what the words mean in this article, not a generic dictionary definition. Then it does two things most reading tools don't. It tells you when what you're reading isn't true. And it listens. UNDERSTAND ANYTHING Highlight a word, a phrase, or a whole paragraph. Get a clear explanation inline, or ask for the wider view. Ask a follow-up. Ask for a real-world example. Highlight a single word and you get an instant entry from a real dictionary rather than a model's paraphrase of one. Highlight something in another language and Translate appears. Highlight something long and Summarize does. The options follow what you selected instead of crowding the screen with buttons that don't apply. Double-tap Shift anywhere to just ask a question, about the page or about anything else. Conversations are kept, so you can reopen a thread days later and carry on. Need to work on text rather than read it? The text area turns the panel into a scratch editor: humanize, paraphrase, shorten, expand, summarize, make it formal or casual, or fix the grammar. CHECK WHAT YOU'RE READING Run a fact-check and JustClarify underlines the sentences making checkable claims, then shows a verdict and the sources behind it, on the page, where you're already reading. Check the article you're on. Check a YouTube video from its transcript, with timestamps on every claim. Or listen to a tab live and check claims in a stream, a debate or a podcast as they're spoken. (Live listening uses your own Deepgram key.) It looks first for a ruling a human fact-checker has already published: PolitiFact, Snopes, FactCheck.org, AFP and hundreds more. If one exists, that's what you see, with a link to read it yourself. If nobody has ruled on it, it searches the web and shows you what current sources say, with the citations attached. TALK TO IT Hold Shift, say what you want, let go. "Explain this." "Is that true?" "Read this to me." "Scroll down." "Find the part about pricing." "Open Supabase." "Click sign in." "Go back." "Reopen that tab." "Undo." Ordinary commands are matched on your own machine in microseconds and never reach a model at all. Only what that grammar can't place gets sent anywhere. And nothing is captured unless you are physically holding the key down, which is also how it knows you've finished speaking. WHAT IT WON'T DO It won't rule on opinions, predictions or promises. Those aren't facts. It won't hand you a verdict it can't back with a source you can click. It says "unverifiable" when the evidence doesn't settle it, rather than guessing to seem useful. It's a place to start checking something, not the last word. Every verdict shows its sources so you can decide for yourself. NO ACCOUNT. NO SETUP. Install it and start highlighting. No sign-up, no API key required, free during early access. If you'd rather run it on your own AI, there are two ways. Paste an API key from Anthropic, OpenAI, Google or Hugging Face and your requests go straight to that provider, never through our servers. Or point it at the ChatGPT, Claude or Gemini account you already pay for, and it will answer from your subscription in a tab of its own that never touches the ones you're working in. PRIVACY JustClarify only reads what you ask it to. It doesn't log or transmit the pages you visit. The microphone is live only while you are holding the key. Saying "open" followed by a site name checks your browser history locally, so it opens the site you meant instead of guessing an address. That check never leaves your browser. When you fact-check a page, the result is saved so the next person reading that page doesn't pay for the same check twice. That's what keeps fact-checking free, and it means the page address and short excerpts of the checked sentences are stored on our servers and can be shown to other users. So don't fact-check private or internal pages. Full details: https://justclarify.xyz/privacy-policy BUILT FOR Students working through dense material. People reading news and long articles. Anyone who wants to understand something difficult, or check something that smells off, without breaking their concentration.
