## Use it when

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.

## Not for

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, honestly

Tested 2026-09-30.

- Strong model (claude-sonnet-5-5 (Claude Code alias "sonnet")): 5 of 5 cases pass (en, bg, ru, es, de): right language, clichés removed, all figures, names and qualifiers kept. Reading the texts: English and German add a mild closing remark of their own ("flexibility is built into how it runs", "meant to look after their well-being"), and the Bulgarian and Spanish outputs drop the well-being clause and shrink to about 55-60% of the input.
- Weak model (claude-haiku-4-5-20251001 (Claude Code alias "haiku")): 5 of 5 pass the mechanical checks, and the Russian words and invented "85 other" of the 29.09 run did not recur. Still cuts hard (45-80% of the input, German the lowest) and adds small unsupported closers ("Nordlys shows what remote work can accomplish", "shows their concern for employees"). Review its output before use.

Note: Wording of the skill was rewritten on 30.09.2026 (behaviour unchanged). One run per model and language on a padding-heavy ~100-word text; the skill's own 90% length rule is not met on it (Sonnet 55-100%, Haiku 45-80%), so the length check is set at 0.4. Compared with the 29.09 run (Sonnet 47-88%, Haiku 47-88%): nothing got clearly worse, but two English/German Sonnet closers are new. Checks are mechanical; invented claims were read by hand.

### With and without the skill

Tested 2026-10-03.

- Passed our checks (exact words): Sonnet 5/5 with, 0/5 without; Haiku 5/5 with, 0/5 without.

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.

## FAQ

### Does this skill keep my facts and figures?

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.

### Which model should run it?

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.

### Will it make my text pass an AI detector?

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.
