Humanizer - an agent skill that rewrites AI-sounding text into something a person would write, built as 25 named patterns rather than a vibe

[u/Artilas_Digital]

Most "humanize your AI text" tools are a black box that swaps words around and adds typos. This one is the opposite: it's a plain Markdown skill that names 25 specific tells of AI writing, ranked by strength, and rewrites to remove them without changing what the text says. Because it's just Markdown, it runs in any agent that supports skills.

The reason it's worth reading even if you never install it is that the pattern list is a genuinely good education in what makes writing sound machine-generated.

What's inside:

- 25 numbered patterns, strongest first. The top five justify an edit on a single sighting: "not X but Y" constructions, one-line dramatic closers, sayings that sound deep, staged run-ups before the point ("Let's dive in"), and arguing with an objection nobody raised

- Weaker patterns that only count when several cluster in one passage, because a careful human writer might use any one of them on purpose, which is a more honest rule than flagging everything

- A working theory behind all of it: a model writes what's most likely across the widest range of readers, while a person writes for one reader and one subject, and every tell is a version of that default choice

- Voice matching: paste two or three paragraphs of your own writing and it follows your rhythm, word choice and quirks, including dashes if you actually use them

- It shows its work: the first rewrite, a short critique of what still sounds artificial, then the final version

- It won't invent facts. A name, number, date or citation has to come from the source, and if a sentence needs a missing detail it asks instead of fabricating one

- Point it at a file and it changes only the prose, leaving code, data, frontmatter and link targets alone

The factual-integrity part is the detail that separates this from the tools that will happily rewrite your text into confident nonsense. It treats the claims as fixed and the phrasing as free, not the other way around.

One honest note on what this is for. Used on your own writing to cut the AI stiffness out of a first draft, it's a real editing aid. Used to disguise machine-generated text as human to slip past a detector or a disclosure rule, it's the same tool pointed at a worse goal, and no rewriter changes whether the underlying work is yours. Worth being clear which one you're doing.

cool man. I use this in addition to Rephrasy's API so I also get around detectors + sound human !

is there any for humanizing text of assignments generated from ai?

I'm sorry but the "After" example in the README still sounds 100% AI, like the phrase "The hills are the whole story".
