What it is

AI Detector Writer is a web-based AI content detector that analyzes pasted text or uploaded files to estimate how much of a document appears human-written versus AI-generated. The homepage presents it as a free tool with real-time results and no stated usage limits.

The site says users can paste text, upload `.txt`, `.md`, or `.csv` files, or submit multiple files for batch checking. It also claims sentence-level highlighting, PDF report generation, and support for multiple languages, making the tool useful for quick review of articles, assignments, and other text before publication.

Core features

Text paste and file upload

Users can paste text directly into the detector or upload `.txt`, `.md`, or `.csv` files for analysis.

Batch file upload

The page says multiple files can be uploaded at once and checked in the dashboard.

Sentence-level highlighting

Results are described as showing AI-written sentences with a gauge for the proportion of AI contribution in the text.

High-precision model
