AI Detector

Check whether text is likely AI-generated or human-written.

AI Detector is an AI checker that helps you assess whether text is likely AI-generated or human-written. Paste text into the side panel or check a selected passage directly from a web page. HOW TO CHECK TEXT • Paste text: open AI Detector, paste the text you want to check, and click “Check”. • Check selected text: highlight a passage on a web page, right-click, and choose “Check if AI wrote this”. The side panel opens and starts the analysis. UNDERSTAND YOUR RESULTS AI Detector displays an estimated AI probability, a model confidence score, and a result label such as “Likely AI”. These indicators help you interpret the analysis. The AI probability estimates how likely the submitted text is to be AI-generated. Model confidence is a separate indicator of the model’s confidence in its assessment; it is not a guarantee of accuracy. FEATURES • Check up to 20,000 characters per analysis. • Analyze selected text through the right-click menu. • Review results in a side panel alongside the current page. • See AI probability and model confidence together. DATA HANDLING Text you choose to check is sent to our server and forwarded to TypeSafe AI for analysis. An internet connection is required. Our server does not store the submitted text. TypeSafe AI handles it according to its own privacy policy. The extension does not track your browsing history. The service uses your IP address to limit request frequency and help prevent abuse. See our Privacy Policy for more details. IMPORTANT LIMITATIONS AI detection can make mistakes. Human-written text may be flagged as AI-generated, and AI-generated text may be assessed as human-written. Results are estimates, not proof of authorship. Use them as one input to your review, alongside context and other evidence. Do not use the result alone to make academic, employment, or other consequential decisions about someone.
