AnyAIZeroAI Detector & Humanizer FAQ
Everything about our free AI detector and humanizer: accuracy, limits, privacy, and more.
🔍 AI Detector
Our DeepSense™ engine analyzes text across multiple linguistic dimensions simultaneously. Each dimension is independently scored, and the results combine into the overall AI probability you see in your report. Instead of a single black-box percentage, you get a transparent breakdown showing exactly which patterns were detected and why.
Our detector identifies text from ChatGPT, Claude, Gemini, Llama, Mistral, Copilot, DeepSeek, and other leading AI models. If it was written by an AI, our engine will flag it.
Yes, free to use. Check essays, articles, reports, creative writing, and more. Subject to fair usage limits.
Our DeepSense™ system delivers consistently reliable results across diverse text types, from academic essays and business reports to blog posts and creative writing. Instead of a single black-box number, you get a transparent breakdown showing exactly which patterns were detected and why. Results are provided for reference, but the level of detail you get is what sets this apart.
We require at least 30 words for detection to run. For best results, we recommend checking full paragraphs or complete documents.
Yes! The Batch mode lets you upload up to 20 files at once (10 MB each). Paste text, TXT, DOCX, or copy paragraphs from PDFs. Each file gets its own detection result with a full dimension breakdown. You can also export individual or batch PDF reports and TXT summaries for all checked items.
📝 AI Humanizer
Yes. You get a free daily word allowance, enough for essays, articles, and most professional documents. No hidden fees. You can also unlock bonus words by sharing, inviting friends, or watching a short ad.
We offer 6 modes tailored to different use cases: Standard (balanced, natural rewrite), Natural (conversational, everyday tone), Academic (formal tone for essays & research), Casual (friendly, relaxed), Professional (business-ready polish), and Concise (trimmed to essentials). Each mode applies a different rewriting strategy. Pick the one that matches your needs. You can also re-check humanized text with our built-in AI detector to confirm the result.
Our humanizer is designed to produce natural human-quality text that significantly reduces AI detection scores. While no tool can guarantee passing every detector every time, our engine is designed to produce convincingly human-sounding output.
Never. All text is processed in real time and discarded immediately. Nothing is saved.
