Frequently asked questions
Is the AI detector free? Do I need to sign up?
Yes, it's completely free and there's no sign-up or account required. Paste your text and run it — the AI content detector, grammar checker, summarizer, and translator all work with no login and no payment.
Is my text stored or shared?
No. Your text is sent over an encrypted connection, used only to produce your result, and not saved to our servers. Your recent-inputs history is kept only in your own browser.
How accurate is AI detection?
It's an estimate, not a verdict — detection is probabilistic and this tool is in beta. Always pair the result with your own judgment; never use it alone for high-stakes decisions about grades, jobs, or reputation.
What do the categories mean?
Each score estimates how much of the text matches AI-generated, AI-refined, or human-written patterns, with the specific sentences and phrases that triggered the score highlighted.
Can I check for plagiarism and paraphrase text too?
Yes. Alongside the AI detector there's a free grammar checker, summarizer, translator, paraphraser, humanizer, and an originality/plagiarism check — all in one place, no account needed.
