Rewrites AI-sounding prose so it reads like a person wrote it — in any language, without dropping facts. Use when asked to humanize a text, make it sound less AI-generated or less like ChatGPT, or clean machine phrasing out of an article, post, email, product description or page.
Humanize AI Text is a tested SKILL.md that rewrites AI-sounding prose so it reads like a person wrote it — in any language, without dropping facts; an agent buys it once for $0.05 over x402.
Passing AI-detector checks, translating, fact-checking, or expanding a short text. It edits the wording of a text you already have, and on padded passages it can shorten them a lot, so read the result before you publish it.
Tested 2026-09-30 with a strong and a weak model.
| Sonnet | Haiku | |||
|---|---|---|---|---|
| with | without | with | without | |
| Passed our checks (exact words) | 5/5 | 0/5 | 5/5 | 0/5 |
One run per model and language (en, bg, ru, es, de). The check looks for exact words, so a synonym counts as a miss and the gap looks bigger than it is. Reading the answers: without the skill "usually" disappeared and claims became firmer than the original; Sonnet mostly kept conditions such as "unless" in other words; Haiku rewrote non-English texts in English, the language of the request.
Same cases and the same checks with and without the skill. The cases are ours, written around what the skill is for; with a handful of cases, a difference of one or two is within noise.

v10.1.2 · 2026-10-04
- Test summary: the same cases with and without the skill, per model, now shown next to the verdicts, including where the skill made no difference. The skill file itself is unchanged.
v10.1.1 · 2026-10-03
- Licence section: the note telling the agent to skip it now reads "ignore it while you work" instead of "ignore it while rewriting text", which was written for one skill and read oddly in the others. The skill's own instructions are unchanged.
v10.1.0 · 2026-09-30
Wording rewritten in our own words; behaviour unchanged.
v10.0.0 · 2026-09-30
First public release as a file: you buy SKILL.md once and keep it. Versions up to 9.x were a paid run on our server; that service is retired.
With the strong model it did: every figure, name and qualifier from the source survived the rewrite in English, Bulgarian, Russian, Spanish and German. The small model did not always keep the facts. Where the source was full of filler, both outputs came out shorter than the input, sometimes by half, so compare the two before you replace anything.
Use a strong model. Claude Sonnet returned clean rewrites in the same language as the input on all five test texts. The small model, Claude Haiku, put Russian words into Bulgarian output, made grammar errors, invented facts in English and Bulgarian, and once changed the meaning.
We do not claim that and did not test for it. The skill aims at prose that a reader finds natural: fewer stock phrases, less padding, plainer sentences. Detector scores depend on the detector and change over time, so no seller can honestly promise a pass.
We asked Claude Sonnet and Haiku to humanize one text in five languages. Without rules, all ten answers lost the word usually, and some invented facts.

Editing & Proofreading
Proofreads a text with minimal intervention, in the language of the text. Fixes spelling, grammar, punctuation and obvious typos, keeps everything else, and returns the corrected text plus a short list of changes for review. Use when asked to proofread, correct, spell-check or fix the mistakes in a text without rewriting it.
Research & Summaries
Writes a faithful summary of a text in the text's own language, using only what the text says, with every number, name and date kept exactly and every qualifier kept. Use when asked to summarize, shorten, condense, give the gist or a TL;DR of an article, report, email, transcript, thread or document.
Marketing & Copy
Writes a short, honest first outreach message to a stranger in business, in the recipient's language, with a subject line, one specific reason for writing and one small ask. Use when asked to write a cold email, a first outreach message, a sales or partnership introduction, or a prospecting note, in any language.
Writing & Rewriting
Cuts a text down to a stated limit (words or characters) by editing the author's own text, keeping every number, name, date, address and qualifier of every fact that stays, and counting the result so it is under the limit. Use when a text must fit a field with a maximum length, such as a social post, a notification, a slide line, an abstract, a form box or a short description, or when asked to cut, trim or shorten a text to N words or N characters.
