About CAPTCHA Validator
Each round, you're presented with a classic CAPTCHA challenge — distorted text, image grids, sliders — and your job is to crack it the way a human would. As you work through the puzzles, the app surfaces what's actually happening under the hood: why the characters are warped, how a grid-click test filters out bots, and what makes these checks surprisingly hard to automate. It's a genuinely clever way to turn something most people dismiss as an annoyance into a teachable moment.
This sits squarely in the education category, leaning toward anyone curious about web security, digital literacy, or just how the internet protects itself from automated abuse. No prior technical knowledge needed — the explanations stay plain and visual throughout.
It runs entirely in the browser with mouse clicks and keyboard input; sessions are short, usually under ten minutes, making it a solid pick for a quick lunch-break experiment or a classroom demo on cybersecurity basics.
