TextClean: clean, inspect and score any text.

Paste any text and get it cleaned, inspected and scored: hidden characters, AI-style signals, personal data, readability, originality against your own sources, and deterministic rewrites. Everything runs in your browser; nothing is uploaded.

Scores are local heuristics, not proof of authorship or factual truth.

What changed

Important: AI-authorship signals from text alone are probabilistic heuristics. They can be wrong, especially after editing, translation, short text, or model updates. Treat these as signals, never proof.

On-device AI detector

Optional second opinion from a neural detector (RoBERTa fine-tuned on the RAID benchmark, MIT-licensed) running entirely in your browser. The first run downloads ~130 MB of model weights from a CDN and caches them — your text still never leaves this page.

Rewrite without an LLM

These modes use transparent deterministic edits. They improve hygiene and style, but do not pretend to be a full generative rewrite.
