AI Text Detector — Free, No Upload, Browser-Based
Paste any piece of writing to get an instant heuristic estimate of whether it was written by AI. The detector analyses phrase patterns, transition word overuse, AI-associated vocabulary, sentence uniformity, and vocabulary richness — the clearest surface-level signals that distinguish AI output from human prose. All analysis runs locally in your browser: your text is never uploaded, never sent to a server, and never stored anywhere.
Sådan bruger du dette værktøj
- Open the tool and paste or type any text you want to analyse (at least 30 words).
- Read the AI likelihood score and the signal breakdown — flagged phrases and transition words are highlighted in the results panel.
- Review the matched AI phrases and overused transition words to understand which parts of the text triggered the score.

Detection is based on heuristic signals (phrase patterns, vocabulary richness, sentence uniformity). It is not infallible — skilled human writers may score high; polished AI text may score low. All analysis runs locally in your browser; no text is sent anywhere.
