Roop AIとは
Check how AI-written a page or selection sounds, learn why, and humanize it. Works offline. No account. Optional BYO API key. Is that article written by a person — or by a chatbot? Roop AI tells you in one click, shows you exactly why, and can rewrite the text to sound human again.
WHAT IT DOES
- AI-score any web page, or just the text you select (right-click → "Analyze selection with Roop AI"), or paste text into the popup.
- Get a 0–100% "AI-written" score with a clear verdict and a confidence level.
- Learn WHY: every score comes with an explained breakdown — AI-favorite phrases ("delve", "moreover", "it's important to note"), flat sentence rhythm, templated openers, rule-of-three lists, "not only… but also" framing, missing human fingerprints, and more. Each signal shows real evidence quoted from the text.
- See the most AI-sounding sentences flagged individually, with reasons.
- Humanize: one click rewrites the text — cutting clichés, restoring contractions, varying sentence rhythm — then re-scores it so you can see the before → after difference, plus a full change log and tips to make it even more human.
- "How it works" built in: a 5-step explainer (the ? button) teaches exactly what gets measured and how the score is formed — no black box.
- Light, dark, or follow-system theme (light by default).
TWO ENGINES — YOUR CHOICE 1. Local mode (default, free, private): a stylometric analyzer that runs 100% on your device. No API key, no account, no network requests, no data ever leaves your browser. Instant results even offline. 2. Bring Your Own Key (optional): plug in your own Anthropic (Claude), OpenAI (GPT), or Google (Gemini) API key for deeper, model-graded detection and higher-quality humanizing. Your key is stored only on your device and used only to call the provider you chose — Roop AI has no servers at all.
BUILT FOR PRIVACY
- Minimal permissions: it can only read a page when you explicitly ask it to analyze that page.
- No tracking, no analytics, no accounts, nothing sold — there's no backend.

WHO IT'S FOR Editors and content leads screening submissions · teachers and reviewers · SEO and marketing teams keeping copy off the "AI slop" radar · writers who use AI drafts but want the final text to sound like them.
HONEST LIMITATIONS No AI detector — including this one — is proof. Scores are statistical estimates: short texts are less reliable, and formal human writing can look AI-ish. Roop AI always shows its reasoning so you can judge for yourself, and never claims certainty. Please don't use any detector score alone to accuse or penalize a writer.
