Install it in one line — paste a single command into Claude, ChatGPT or Cursor and it writes the skill into your project.

Free, and about thirty seconds: a work email and a six-digit code.

What this skill does

Takes a draft that sounds AI-written and rewrites it to sound like you — for investor updates, broker emails, LinkedIn posts and loan-program pages. It removes the tell-tale phrasing without changing what the text says.

What it does

  • Finds the patterns that make text read as machine-written
  • Rewrites them in a plain, direct voice
  • Keeps every fact, number and commitment as it was
  • Can match a writing sample you provide
  • Explains what it changed and why

When to use it

  • An AI draft of an investor letter or newsletter reads like a template
  • Outreach emails all sound the same
  • Editing website or marketing copy before it goes live

What to have ready

  • The draft to rewrite
  • Optionally, a sample of your own writing to match

How to use it

  1. Download it with the button above. You'll sign in with a work email — that's how the creator knows who is using their skill.
  2. Copy the install prompt from the "Run it in Claude" box, and paste it into Claude along with the file. Claude installs the skill, fills in your firm's details where the file has [BRACKETED] placeholders, and runs a quick test with you.
  3. Then just ask in plain English. Claude picks the skill up on its own when a request matches it. Anything it still needs, it asks you for — it won't invent a number.

"Humanize this investor update draft so it sounds like me, not a template."

What you get back

A rewritten draft, plus a short list of what was changed.

Good to know

  • Output quality tracks input quality. A missing figure is flagged as missing — it is never estimated to fill a gap.
  • Every draft is a starting point for your own review, not a finished decision.
  • Runs anywhere Claude does: the Claude app, Claude Desktop, or Claude Code.
  • It changes style, not substance, but check every number and term afterward. Where rules or your own policies require disclosing AI-assisted content, still disclose it.

Nothing it produces is a commitment to lend or an offer to sell a security.

Humanizer: remove AI writing patterns

Rewrite AI-sounding text so it reads like the writer, not a chatbot. Keep what it says. Do not make anything up.

Why AI text sounds the way it does

A language model writes whatever is most likely to come next, so by default it makes the choice that fits the widest range of readers and subjects. A human writer chooses for one reader and one subject, so their choices are uneven and specific. Every pattern below is one form of the default choice:

  • Staging. The sentence signals importance instead of adding a fact, with a contrast that only adds weight or a one-line closer that repeats the point.
  • Rhythm by rule. Triads and dashes applied everywhere, whether or not the meaning asks for them.
  • Inflation. Ordinary facts dressed as pivotal or expert-backed.
  • Formatting by rule. Bold and title case applied to every item.
