About AI Content Detector
The AI Content Detector estimates how likely a text was written by AI. Paste up to 20,000 characters and get an AI-probability gauge with a confidence level, a written analysis, a signal-by-signal breakdown showing what points to AI versus human, and a passage breakdown highlighting the most AI-like and most human-like sections.
Two sensitivity modes tune the verdict: balanced avoids over-calling AI on mixed signals, while strict leans toward an AI verdict when signals are ambiguous. Verdicts range from likely human-written through possibly AI-assisted to likely AI-generated, and the full report can be copied or downloaded.
AI detection is probabilistic and can be wrong, especially on short or heavily edited text: treat the score as a signal, not proof. Detection runs on the server and uses credits from your account.
How to use AI Content Detector
- Paste the text you want to analyze: up to 20,000 characters.
- Pick a sensitivity: balanced (avoids over-calling AI) or strict.
- Click “Detect AI content” and wait while predictability, rhythm and variation are measured.
- Read the AI-probability gauge, the confidence level and the verdict.
- Review the detection signals and the passage breakdown, then copy or download the report.
