 # Botfilter
 
-[Botfilter](https://botfilter.io) is a browser extension that scores English text for “likely AI-written” as a calibrated probability, on the device. A score can be wrong and should not be used as proof of authorship.
+[Botfilter](https://botfilter.io) flags AI generated text on websites you visit. Filter AI slop in your feeds, AI spam in your inbox, AI generated articles, and more.
+
+- Choose how it looks: "Outline" flags in place, "Collapse" folds a post to a one-line label, "Hide" removes it.
+- Choose how much it flags: "Fewer", "Balanced", or "More".
+- Flags posts, comments, and emails on X, Reddit, LinkedIn, Gmail, YouTube, and Hacker News. Flags paragraphs on every other website. Disable for any site from the toolbar button.

+Botfilter is a free and private alternative to Pangram. It uses a specially trained AI model small enough to run in your browser. Everything runs on your device. No page text, score, or usage ever leaves your browser. No account required.

+The model scores English text as a calibrated probability of being AI-written. A score can be wrong and should not be used as proof of authorship.
 
 Each `releases/<version>/` directory contains the ONNX model, the WordPiece vocabulary, the calibration settings, and a lockfile with SHA-256 checksums. Use all files from the same version. The extension’s [inference implementation](https://github.com/hraness/botfilter/tree/78d39e6debbff69b66661a760c0cca0f1b64a629/extension/src) defines preprocessing, window aggregation, and calibration; these files do not provide a Transformers pipeline.
