# Phravv

> Phravv is a high-fidelity paraphrase tool at https://www.phravv.com. Paste text. Get a high-fidelity paraphrase. Same meaning. New wording.

Phravv rewrites pasted text while keeping facts, names, numbers, dates, quotations, URLs, heading lines, and fenced code. Light, Balanced, and Aggressive decide how far the sentences move. They are not stealth settings.

A thorough paraphrase can degrade Anthropic Claude’s statistical token watermark (a SynthID-Text-style pattern in token choice, not hidden characters). That is not a guarantee. Short text is inconclusive. Phravv is not a detector and never rewrites with Claude.
