Paste any text and instantly see every trace a chat interface left behind: hidden HTML class names, zero-width characters, unusual spaces, and typography quirks. Each finding comes with a count and a position, so you know exactly where these artifacts are, based on the actual bytes, not a probability guess. Clean them all with one click. It's free, unlimited, and requires no account. Everything runs in your browser, so your text never leaves your device. Just to be clear, it doesn't claim to detect Anthropic's statistical watermark, because no one outside Anthropic can. The engine is open source under MIT.
