Claude replies. Press one button and CONTEXA asks a few short questions you answer by clicking, then writes the whole prompt. Create magic in Claude. Most people using Claude get stuck in the same place: they know roughly what they want, but not how to ask for it. The answer comes back generic, because nothing in the question told Claude what they actually needed. CONTEXA fixes that from inside the conversation — without making you write the question. HOW IT WORKS When Claude finishes replying, CONTEXA puts one small button above your message box. That is all it does. Nothing is generated, nothing is sent, and nothing about your conversation leaves the page. Press the button and CONTEXA reads that reply and gives you one of two things. Usually it asks you a few short questions — never more than four, and only the ones that would actually change the answer. What's the occasion? How long should it run? Which language? You don't have to type: you pick from answers written for you, one question at a time, and you can skip anything you don't care about. Sometimes the reply didn't leave a question — it left a move. Then you get up to four of those instead: take it further, you choose, what could go wrong, why this way. One click and it becomes your next message. Either way, CONTEXA writes the whole prompt into your message box. You read it. You change anything you like. You press send. CONTEXA never sends anything for you and never talks to Claude on your behalf. IT ONLY WORKS WHEN YOU ASK IT TO The button is the whole interface until you press it. That is deliberate: no pop-ups appearing while you read, no suggestions you didn't ask for, and nothing spent on a reply you were never going to follow up. CLICKING IS ALL IT ASKS OF YOU Every question is answerable by picking one of the answers on screen. If CONTEXA can't write answers that genuinely cover a question, it doesn't ask it. IT KNOWS WHEN TO SAY NOTHING If Claude's reply left nothing open, CONTEXA asks nothing at all. No filler, no made-up suggestions to look busy. It speaks when there is something worth asking and stays quiet the rest of the time. TYPE IT ROUGH INSTEAD Know what you want but not how to phrase it? There's a second button for that. Type it rough — "optimize seo & meta" — and CONTEXA turns it into a properly written prompt. IT STAYS OUT OF THE WAY The button sits just above your message box. Scroll up into the conversation and it folds away so nothing covers what you are reading; come back down and it returns. A small nudge of the wheel does nothing at all. If you dismiss it twice in a row it offers to stay quiet for the rest of the tab. FREE, AND NOTHING TO SET UP No account. No sign-up. No credit card. No API key. Install it and it works on your next message. Fair use on the free service is 20 prompts a day — and because nothing happens until you press the button, a reply you don't follow up on costs you nothing at all. If you want unlimited use, you can paste your own Anthropic API key in Advanced settings; in that mode requests go straight from your browser to Anthropic, and your key never touches our server. PRIVACY No login. No personal data. No tracking. No analytics. No ads. Nothing about your conversation leaves your browser until you press the button. No button pressed, no request made. An anonymous per-install token exists for one reason: so the free service can count your daily allowance. It is not tied to you, your account, or your conversations. SUPPORTED BROWSERS On desktop: Google Chrome. On Android: CONTEXA works in Android browsers that support Chrome Web Store extensions. Lemur, Mises and Quetta are confirmed. Chrome for Android does not support extensions of any kind, and never has. One thing worth knowing on Android: signing in to claude.ai with "Log in with Google" can fail right after you enter your password in these browsers. Sign in with your email address instead and it works normally. That is a browser limitation on the sign-in page, not CONTEXA — but it looks like a broken extension if you don't know. Not supported: Firefox and Safari on any platform, and the Claude mobile app. Browser extensions cannot reach inside a native app. CONTEXA is an independent product that works on claude.ai. It is not affiliated with, endorsed by, or connected to Anthropic.
