About AIDetector365

AIDetector365 is a free platform for checking whether text may be AI-generated and for improving your own writing. Every tool is free to use with no login, no registration and no subscriptions.

Our principles

• Free for everyone. The site is supported by advertising, not by paywalls.
• Private by design. No accounts and no server. Detection and writing tools run entirely in your browser.
• Honest about limits. AI detection is probabilistic. We explain results and never claim certainty.

Who we serve

Students checking their own work, teachers looking for a starting point for fair conversations, bloggers and agencies reviewing content quality, and anyone curious about how AI writing differs from human writing.

What we offer

AIDetector365 brings together two kinds of tools. Detection tools — the AI Detector, AI Writing Detector, AI Content Detector, AI Text Checker and AI Paraphrase Checker — estimate whether text shows patterns typical of AI-generated writing and explain their reasoning sentence by sentence. Writing tools — including the AI Humanizer, paraphraser, sentence rewriter, grammar checker, summarizer, translator and dictionary — help you improve clarity and flow. The Readability Checker and Word Counter measure your text as you type.

How we approach AI detection

AI detection is an estimate, not a fact. Our detector reports an AI probability together with a confidence level, the signals behind the result and the limitations that apply to your text. Confidence is deliberately conservative: short samples, formal or templated writing and mixed signals all lower it. We do not claim a fixed accuracy percentage, because real-world accuracy depends heavily on the text, its length and how it was edited.

We believe a detector should start a conversation, never end one. That is why every result page reminds readers not to use a score as the only evidence that someone used AI.

How we handle your text

We do not require an account and we do not keep a history of what you check. Detection, writing and statistics tools run in your browser, so your text never leaves your device. Only the translator and dictionary send text to public third-party services to fetch a result. Preferences and drafts you choose to save are kept in your own browser. Read the details in our Privacy Policy.

Our guides and articles

Our blog is written by the AIDetector365 Editorial Team. Articles explain how AI detection works, how to write well with and without AI, and how teachers, students and publishers can use these tools fairly. We review articles periodically and show the last-updated date on every guide.

How the site is funded

AIDetector365 is free to use. We may show ads served by Google AdSense to cover running costs. Ads never affect detection results, and we do not sell access to better or paid results — there is no paid tier.
