Detect and remove Google's SynthID watermark from AI-generated text. Our humanization technology rewrites your content so statistical watermark patterns are fully eliminated.

SynthID Detector &

Watermark Remover

Rephrasy regenerates the text using different vocabulary and sentence structures — new tokens mean the SynthID pattern is broken.

AI rewrites the tokens

Your text is rewritten to read naturally, pass AI detectors, and carry no SynthID statistical signature.

Clean, watermark-free output

Copy your content from Gemini, ChatGPT, or any other AI tool into the Rephrasy editor.

Paste your AI-generated text

SynthID lives in the statistical pattern of the original tokens. Rewriting the text changes those tokens — and the watermark disappears with them.

Why Humanizing Removes SynthID

SynthID is a watermarking technology developed by Google DeepMind that embeds invisible statistical patterns into AI-generated text. Originally built for Gemini, the technology is now being adopted across the AI industry. Unlike simple Unicode character tricks, SynthID modifies the probability distribution of token selection during generation, making it mathematically embedded in the text itself.

Google acknowledges SynthID is not foolproof. Significant edits, paraphrasing, or humanization can degrade or remove the watermark entirely.

Still experimental

During text generation, the AI model adjusts the probability of selecting certain tokens using a secret cryptographic key. This creates a subtle, statistically detectable signature across the text.

How it's embedded

SynthID watermarks are imperceptible when reading. The text looks and reads completely normally — only statistical analysis can reveal the embedded pattern.

Invisible to humans
