Private browser tool · no account
CleanList normalizes text and URLs, removes exact or lexically similar lines, converts CSV to Markdown and structures lists as JSON chunks. It does not call an AI model.
Similarity is based on spelling and shared words, not meaning. Review important datasets before replacing the original file.
