content highlighter

what is it?

a browser script that uses data sourced from academic research papers and from my own experiences to determine common LLM content patterns that deviate dramatically from how humans normally write.

disclaimer: some the patterns are context-dependent. for example, in a Reddit thread it's less human to write "in conclusion" than it would be in a research paper. use your nose.
