KLEANER is a web-based tool that quickly cleans and polishes AI-generated text — removing formatting noise, correcting grammar and punctuation, smoothing awkward phrasing, normalizing tone, and reducing AI fingerprints. It targets writers, marketers, and teams who post-process AI outputs and can integrate into workflows via editor plugins or API integrations. Documentation notes key capabilities such as noise removal (repetition and filler), grammar and syntax corrections, tone/style normalization, formatting improvements, batch processing, and API access with integration options. Use cases highlighted include blog posts, product descriptions, newsletters, technical docs, and post-processed AI outputs for customer-facing content, as well as team workflows. Privacy, security, and responsible-AI considerations are referenced in the docs.
