AI Humanizer & Text Rewriter

It rewrites your text to sound more natural, varied, and clear. It simplifies overly complex phrases, converts passive voice to active where appropriate, removes redundancy, and improves overall readability — without changing your original meaning.

No. The rewriting engine runs locally: spaCy for tokenising and dependency parsing, curated rewriting dictionaries for phrase and word changes, a local sentence-transformers model for semantic similarity, lemminflect for verb and noun inflection, and a self-hosted LanguageTool for grammar checks. No generative language model or external AI API is called.

That is the goal, and several checks enforce it: each rewritten sentence must keep its names, numbers and negations and stay above a similarity threshold, otherwise the original sentence is kept. No automatic check catches every change in meaning, so review the result before using it.

Up to 5,000 characters per request. For longer documents, split the text into sections.
