How real is this example

For the 3 sample answers, errors were marked by us with a severity (big / medium / small); each level shows a different share. Checking your own typed sentence needs the AI key. Praktika offers a similar Soft / Balanced / Strict switch.

AI: the page first asks our small server function (/api/chat) which holds the AI key; the key is never in the page. No key is set yet, so every reply you see now comes from a script we wrote (badge: 'Bản kịch bản'). Once a key is added on Cloudflare the same page switches to real AI with no code change. Typing works everywhere; the 🎤 button needs Chrome or Edge outside the claude.ai frame.
