Description
Reads the page you're on and quizzes you before it explains. Predict-then-reveal, in the side panel. Guess first. A wrong guess that gets corrected sticks better than reading the right answer cold — the pretesting effect. Most quiz tools show you answers; Cuko makes you commit to one. Open any article, paper, or PDF, hit "Quiz me on this page", and Cuko reads it and quizzes you before it explains. Select a passage first to quiz on just that part. HOW IT WORKS - Each question sets up a tension; you predict the consequence before the reveal. - The reveal explains the mechanism — how to reason about the next question of this shape, not just this answer. - Miss one? An optional chat gives you a second attempt at the exact gap you exposed. It stays on the miss; it won't lecture. - Every quiz is saved on your device — replay it anytime with no regeneration, or export your set to a file. Delete any you don't want. - Reads PDFs too, not just web pages. - Keyboard-first: digit keys answer, Enter advances, Esc exits. No mode to toggle. - Pair your phone with a QR code and the panel mirrors to it over a direct peer-to-peer connection — answer from the couch while the page stays on your desk. SIGN IN AND GO Sign in with GitHub and generation runs on GitHub Models through your own account — no API key, no subscription, no server. Prefer your own model? Paste an Anthropic key (Claude) or an OpenAI key, or use Chrome's built-in on-device AI where your device supports it. PRIVACY The page is read only when you ask, on a per-site permission you grant the first time. Its text goes to the AI provider you chose — GitHub Models, Anthropic, or OpenAI — to generate the questions, or stays entirely on your device with Chrome's built-in AI. Nothing is stored on a server: no account database, no tracking, no analytics. Full policy: https://neves.cloud/cuko/privacy.html
