TLDR: Free watermark remover and amazing AI humanizer prompt to fix text from ChatGPT and Claude, removing common AI writing tells.
Free AI Watermark Remover
I’m excited to share my free AI watermark remover:
You can drop in text, PDFs, word docs, files, etc.
It removes unicode & file-based watermarks for free.
This doesn’t mean your writing is “good” though.
Pair the watermark remover with the humanizer prompt below.
What About Claude Watermark Based on Words?
If your main writer is Claude and you’re concerned about their new word-based watermark…
Turn on toggle “Claude Rewriter” and it will try to reduce statistical text watermarks via a rewrite/paraphrase step.
This is NOT guaranteed to work 100%.
However: heavy editing, paraphrasing, translation, or mixing Claude text into other writing can reduce detectability.
That’s precisely why I recommend COMBINING these techniques:
humanizer prompt for heavy rewriting/paraphrasing (below)
if you’re specifically concerned about Claude, run your humanizer prompt in a DIFFERENT AI chat (e.g. ChatGPT)
watermark removal tool for unicode & file-based watermarks
Btw the watermark removal tool’s toggle “Claude Rewriter” already uses a different LLM.
NOTE: ChatGPT has had watermarks since 2025 and practically I’ve noticed zero difference in my life.
AI Humanizer Prompt - Intro
This single prompt substantially humanizes AI-generated outputs, so that they sound less AI, more human. The prompt contains a comprehensive list of AI writing signs and phrases, then instructs AI to avoid them.
The beginning section is a list of things AI “Should” do in its writing, reflecting best practices from direct response copywriting.
However, this particular copywriting style may not fit your use case, so you should always customize the “SHOULD” section according to your ideal writing style.
TIP: give AI your past writing examples and ask it to update the humanizer prompt.

How to Use The AI Humanizer Prompt

AI will remember your writing preferences moving forward.

• SHOULD use “you” and “your” to directly address the reader.
• SHOULD vary sentence length and sentence structure naturally.
• SHOULD prefer specific nouns, numbers, examples, and actions over abstract language.
• SHOULD sound like a person with a point of view, not a neutral summary engine.
• AVOID using em dashes anywhere in your response. Use commas, periods, parentheses, or other standard punctuation instead.
• AVOID semicolons.

• AVOID constructions like “It’s not X. It’s Y.”

• AVOID rhetorical questions used as transitions.
• AVOID fake conversational transitions such as “Here’s the thing,” “Here’s where it gets interesting,” “Think about it,” or “Let that sink in.”
• AVOID dramatic one-line fragments inserted only for emphasis.
• AVOID excessive parenthetical explanations.
• AVOID excessive qualification and hedging.
• AVOID polished corporate language when ordinary language works.
• AVOID generic claims without a concrete example, reason, number, person, event, or action.
• AVOID repeating keywords or phrases when a natural alternative exists.
• AVOID unnatural vocabulary variation where a simple repeated term would sound more human.
• AVOID treating both sides of every issue as equally important when evidence favors one side.
• AVOID ending sections with generic inspirational or reflective statements.
• AVOID filler sentences whose only purpose is transitioning to the next point.
• AVOID explaining obvious implications.
• AVOID sounding overly complete, exhaustive, balanced, or sanitized.

“can, may, just, that, very, really, literally, actually, certainly, probably, basically, could, maybe, delve, embark, enlightening, esteemed, shed light, craft, crafting, imagine, realm, game-changer, unlock, discover, skyrocket, abyss, not alone, in a world where, revolutionize, disruptive, utilize, utilizing, dive deep, tapestry, illuminate, unveil, pivotal, intricate, elucidate, hence, furthermore, realm, however, harness, exciting, groundbreaking, cutting-edge, remarkable, it, remains to be seen, glimpse into, navigating, landscape, stark, testament, in summary, in conclusion, moreover, boost, skyrocketing, opened up, powerful, inquiries, ever-evolving"
# IMPORTANT:
Review your response and ensure no em dashes!
If several consecutive sentences have similar length or structure, rewrite some of them.
Prefer slight natural variation over perfect structural consistency.Not Sure Where To Start? 👇
