Humanise the Tone

4 prompts

Rewrite It So It Sounds Human

1/20

Rewrite the text below so it reads like a real person wrote it, not an AI. Keep every fact and my core meaning. Vary sentence length, use plain everyday words, and let it breathe. Text: [PASTE YOUR TEXT]

The all-purpose humaniser. A fast first pass that loosens up stiff, over-polished Claude output.

💡

Pro tip: Run it once, then read the result out loud. If a line feels stiff, paste just that line back and ask for one more pass.

Make It Conversational

2/20

Rewrite this to sound conversational, like I am explaining it to a smart friend over coffee. Use contractions, short sentences, and a natural rhythm. No hype, no filler. Keep it clear. Text: [PASTE YOUR TEXT]

Turns formal, essay-stiff writing into something warm and easy to read.

💡

Pro tip: Conversational does not mean sloppy. If it gets too casual, add 'keep it smart, just not stiff' to the prompt.

Add a Human Warmth Pass

3/20

Keep my words mostly intact but add warmth and personality so it does not read like a corporate memo. A little opinion and a light touch are fine. Do not add fake enthusiasm or exclamation marks. Text: [PASTE YOUR TEXT]

For copy that is correct but cold. Adds a human pulse without rewriting from scratch.

💡

Pro tip: Great for About pages, bios, and welcome emails where a flat tone kills trust.

Write at a Grade 7 Reading Level

4/20

Rewrite this at a grade 7 reading level so anyone can read it fast. Short sentences, common words, one idea per sentence. Do not dumb down the meaning, just make it easy. Text: [PASTE YOUR TEXT]

Simple language is what most human writing actually looks like. This forces clarity.

💡

Pro tip: Lower reading levels almost always read more human, because real people write plainly.

Remove AI Tells

5 prompts

Strip the Classic AI Phrases

5/20

Rewrite the text below and remove AI tells. Ban these phrases: 'in today's world', 'it is worth noting', 'in the ever-evolving landscape', 'delve into', 'navigate the complexities', 'a testament to', 'the digital age'. Cut the over-balanced 'not only but also' pattern. Vary sentence length and use plain words. Keep my meaning and facts. Text: [PASTE YOUR TEXT]

Targets the exact stock phrases that scream machine-written. The single most useful de-AI prompt.

💡

Pro tip: Keep your own ban list. Every time you spot a tell in Claude's output, add it to this prompt.

No Em Dashes, No AI Punctuation

6/20

Rewrite this and follow strict punctuation rules: use zero em dashes and zero en dashes, replace them with a comma, a period, or a rewrite. Avoid the rule-of-three list pattern ('fast, simple, and powerful'). Do not start sentences with 'Moreover', 'Furthermore', or 'Additionally'. Keep meaning and facts. Text: [PASTE YOUR TEXT]

Em dash overuse and tidy three-item lists are two of the loudest AI fingerprints. This kills both.

💡

Pro tip: The em dash tell is strong. If you only fix one thing, fix this one.

Cut Clichés and Filler

7/20

Rewrite this and delete every cliché, filler word, and empty intensifier. Remove 'very', 'really', 'truly', 'essentially', 'basically', 'at the end of the day', and 'when it comes to'. If a sentence adds no information, cut it. Keep the facts. Text: [PASTE YOUR TEXT]

Real writing is dense. This strips the padding Claude adds to sound thorough.

💡

Pro tip: Ask 'what was cut?' after, so you can spot your own filler habits next time.

Kill the Over-Balanced Sentences

8/20

Rewrite this so sentences are not artificially balanced. Break up any 'not only X but also Y' and 'while X, Y' constructions. Let some sentences be short and blunt. Do not smooth every edge. Keep my meaning. Text: [PASTE YOUR TEXT]

AI loves symmetry. Humans do not always balance their clauses, and that asymmetry reads real.

💡

Pro tip: A few blunt, short sentences in a row is one of the fastest ways to sound human.

Remove the Fake Conclusion

9/20

Rewrite this and delete any summary wrap-up that restates what was already said. No 'In conclusion', no 'Ultimately', no 'By understanding these'. End on a real point or a specific next step instead. Keep the substance. Text: [PASTE YOUR TEXT]

The tidy recap paragraph is a dead giveaway. Real writing usually just ends.

💡

Pro tip: If the last paragraph only repeats the piece, cut it entirely and let the prior line land.

Match My Voice

4 prompts

Learn My Voice From a Sample

10/20

Here is a sample of my real writing. Study its tone, sentence length, vocabulary, and rhythm, then rewrite the second text to match my voice exactly. Do not copy the sample's content, only its style. My sample: [PASTE 200 WORDS YOU WROTE]. Text to rewrite: [PASTE YOUR TEXT]

The most reliable way to sound like you: give Claude a real example to copy from.

💡

Pro tip: Use a sample you wrote fast and unedited. Your rough writing is more you than your polished writing.

Build My Voice Profile

11/20

Read this sample of my writing and describe my voice in a short style guide: typical sentence length, favourite words, words I never use, tone, and rhythm. Then save it as rules I can reuse. Sample: [PASTE YOUR WRITING]

Creates a reusable voice profile you can paste into future prompts instead of the full sample.

💡

Pro tip: Keep the profile in a note. Paste it at the top of any writing prompt to stay on-voice.

Match a Specific Person's Style

12/20

Rewrite this in the style described here, without imitating any real person's exact words: [DESCRIBE THE STYLE, e.g. 'direct, dry humour, short sentences, no jargon']. Keep my facts and meaning. Do not add flattery or hype. Text: [PASTE YOUR TEXT]

For when you know the vibe you want but do not have a sample handy.

💡

Pro tip: Be specific about what to avoid, not just what to do. Constraints shape voice more than adjectives.

Keep My Quirks Intact

13/20

Rewrite this for clarity but keep my personal quirks: my one-word sentences, my habit of starting with 'And', and my casual asides. Fix grammar and flow only. Do not sand off my personality. Text: [PASTE YOUR TEXT]

Editing that improves the writing without erasing what makes it yours.

💡

Pro tip: Name your quirks explicitly. Claude defaults to 'correct', which flattens the things that make you sound like you.

Rewrite for a Format

4 prompts

Human-Sounding Email

14/20

Rewrite this as a short email that sounds like a real person typed it, not a template. Warm but efficient, no 'I hope this email finds you well', no corporate padding. Get to the point in the first line. Text: [PASTE YOUR DRAFT]

Strips the template feel from work email so it reads like you actually wrote it.

💡

Pro tip: The opening line is where emails sound fake. Ask for a direct first sentence every time.

LinkedIn Post Without the Cringe

15/20

Rewrite this as a LinkedIn post that sounds human, not like an engagement-bait bot. No one-line-per-paragraph gimmick on every line, no 'Here is why that matters', no fake vulnerability. Real, specific, and a bit understated. Keep it under 150 words. Text: [PASTE YOUR IDEA]

Avoids the instantly recognisable AI LinkedIn formula while keeping the post readable.

💡

Pro tip: Ban the hook-and-payoff structure by name. It is the format everyone now reads as AI.

Blog Post in a Real Voice

16/20

Rewrite this blog section so it reads like a knowledgeable person wrote it for other people, not for a search engine. Cut keyword stuffing and stock transitions. Use concrete examples over abstract claims. Keep the facts and the structure. Text: [PASTE YOUR SECTION]

Turns generic, SEO-flavoured Claude prose into content people actually want to read.

💡

Pro tip: Concrete beats abstract. Ask for a real example in every paragraph that makes a claim.

Essay That Sounds Like a Student Wrote It

17/20

Rewrite this essay so it reads like a thoughtful student wrote it, not an AI. Keep a clear argument but allow natural imperfection: some longer sentences, a few plain ones, real transitions instead of 'Furthermore'. No inflated vocabulary I would not normally use. Text: [PASTE YOUR ESSAY]

For academic writing that needs to sound like your own thinking, not a generated draft.

💡

Pro tip: Feed in your own vocabulary level. An essay full of words you never say is the biggest tell.

Self-Check and Edit

3 prompts

Flag Your Own AI Tells

18/20

Review the text below and list every phrase, punctuation habit, or sentence pattern that sounds AI-generated. For each one, explain why it reads as machine-written and suggest a human alternative. Do not rewrite the whole thing yet, just find the tells. Text: [PASTE YOUR TEXT]

Uses Claude against itself to surface the tells before you decide what to change.

💡

Pro tip: Run this on your own human drafts too. It is a fast way to learn what reads as robotic.

Rate How Human It Reads

19/20

Score this text from 1 to 10 on how human it sounds, where 10 is clearly written by a person and 1 is obviously AI. Give three specific reasons for the score and the three changes that would raise it most. Text: [PASTE YOUR TEXT]

A quick diagnostic that tells you exactly where the writing still sounds generated.

💡

Pro tip: Chase the three suggested changes, re-score, and repeat until it holds a solid 8 or 9.

Final Human Polish

20/20

Do a final light edit so this reads like a real person's finished draft. Fix awkward phrasing, remove any remaining AI tells, keep zero em dashes, and make sure it sounds like natural spoken English read aloud. Change as little as possible. Text: [PASTE YOUR TEXT]

The last pass before you publish. Minimal changes, maximum naturalness.

💡

Pro tip: End every writing session with this prompt. It catches the one or two tells that slipped through.

Frequently Asked Questions

The most reliable one gives Claude a sample of your real writing and tells it to match your tone, sentence length, and rhythm while keeping the new content. Voice matching beats generic 'sound natural' instructions because Claude has a concrete target to copy. If you do not have a sample, the next best is the ban-list prompt that strips specific AI tells like 'in today's world', over-balanced sentences, and em dashes.

Honestly, no prompt can guarantee it beats an AI detector. These prompts make Claude's writing genuinely more natural by removing the patterns that both detectors and human readers pick up on, so it reads far less robotic. But detectors are inconsistent and often flag real human writing too. Treat the goal as better, more human writing that you are proud of, not as a way to trick a tool. The best defence is editing the output yourself so it truly becomes your own.

Give Claude an explicit ban list. Tell it to remove phrases like 'it is worth noting', 'delve into', and 'a testament to', to avoid the 'not only but also' pattern, to vary sentence length, and to use zero em dashes. The more specific your list, the cleaner the result. Keep adding tells to the list every time you spot one in the output.

Claude is trained to be clear, balanced, and thorough, which produces smooth but predictable prose: tidy three-item lists, symmetrical sentences, stock transitions, and a summary paragraph at the end. Those habits are correct but they are also recognisable. Humanising prompts work by asking for the opposite: uneven rhythm, plain words, blunt short sentences, and no tidy wrap-up.

Yes. Human and professional are not opposites. Add 'keep it smart and professional, just not stiff' to any humanising prompt. Ask for contractions, plain words, and a natural rhythm while keeping your facts and a clear structure. The result reads like a sharp colleague wrote it, not like a corporate template or a bot.
