Yes, AI Detector takes your privacy seriously. It never stores your uploaded content or shares it with third parties.

Absolutely. AI Detector is designed to spot text from popular AI tools like ChatGPT. It analyzes language patterns, structure, and tone that ChatGPT often uses.Whether the text is a short paragraph or a long essay, AI Detector can identify ChatGPT-generated content quickly and clearly.
AI Detector has high accuracy for ChatGPT text - usually over 90% for recent ChatGPT versions. It checks for unique AI markers in ChatGPT’s writing, like repetitive phrases or unnatural flow.While no tool is 100% perfect, AI Detector’s accuracy is reliable enough for most users, like teachers or students.
No, there’s no daily limit for using AI Detector. You can check as many texts or files as you need each day, whether it’s 1 or 50.This is great for busy users, like editors who need to review multiple submissions or teachers checking a class set of homework.
AI Detector’s confidence rate is a percentage showing how sure it is about a result. A 90% rate means it’s very sure the text is AI-generated; 50% means it’s unsure.The tool explains this rate next to each flagged section, so even new users can easily tell how reliable the detection is.
Yes, AI Detector can check mixed AI-human content. It doesn’t just flag entire texts - it marks specific parts that are likely AI-generated. For example,if an essay has a human-written intro and AI body, AI Detector will highlight the AI part, making it easy to fix.
No, you don’t need any tech skills to use AI Detector. Its interface is simple: just upload a file or paste text, click a button, and wait for results.The steps are clearly labeled, and the reports are easy to read. Even if you’re not good with tech, you can use AI Detector without trouble.
First, AI Detector does support editable file types like regular PDFs, PPTs, Word documents, and TXT files — you can upload these directly to check for AI content. However, it can’t work with scanned PDFs right now,as scanned PDFs are image-based (not editable text). If you have a scanned PDF, use an OCR tool to convert it to editable text first.
Yes, you can easily save AI Detector’s report to keep a record of your detection results. After AI Detector finishes analyzing your content - whether you uploaded a Word doc, PPT, regular PDF, or TXT file -you’ll see a prominent “Save Report” button below the results. Clicking this button lets you choose to download the report as a PDF or a TXT file, both of which are easy to open and share later.
AI Detector might flag human text as AI if it has patterns similar to AI writing — like very formal tone, simple structure, or common phrases. For example, a basic essay with no unique ideas could be flagged.But the tool’s confidence rate helps here: a low rate (under 60%) means it’s probably a mistake.
