Remove AI watermarks from text
Paste your text. We strip the hidden characters and rewrite the phrasing that carries watermark patterns, without changing what it says.
Privacy mode
Private 1× credits · Plaintext goes through the Simple Unmark app to the cleaning workload.
The app, the ordinary HTTPS and load-balancer path, the Python workload, and DeepInfra all process plaintext. Text and output are not stored in our database or analytics.
Confidential AI is coming soon. Selecting it registers interest only — no text, no credits.
Privacy modes explainedHow it works
Paste. Clean. Copy.
- Step 1
Paste your text
One box, nothing to set up. Your browser scans for hidden characters as you type.
- Step 2
Clean it
Hidden characters are removed. The wording is rewritten to break up watermark patterns.
- Step 3
Copy the result
Read the cleaned text and copy it.
Private mode is the default. Switch to Confidential and your browser verifies the cleaning service before encrypting text to it — our app never receives it.
Compare privacy modesText is rewritten, so review it before use. No tool can guarantee a watermark detector’s verdict.

FAQ
Common questions
What can I clean?
Paste text to remove hidden characters and rewrite watermark patterns. The rewrite aims to preserve your meaning. Simple Unmark currently supports text only.
Will my text still sound like me?
The wording changes, but the rewrite aims to keep your meaning, facts, names, and tone. Always review the result before using it. No tool can guarantee a watermark detector's verdict.
Who can read my text?
In Private mode, our app and processing services handle your text. Confidential mode encrypts it directly to a verified, protected service, bypassing our app. Our AI provider, DeepInfra, still reads it to do the rewrite. We do not save your submitted text or results in our database or analytics.
Can I try it for free?
Yes. Get 3 free cleans without an account, up to 100 words each. Need more? Create an account for 10 starter credits, then buy more when you need them. There is no subscription.
What is Confidential AI?
It is our coming-soon mode, designed to keep both cleaning and the AI rewrite inside a protected environment without sending text to an external AI provider. Register your interest in the cleaner; it does not submit your text or spend credits.
