The AI Slop Filter
Make AI sound like you
Donors can feel it when a letter was written by AI. This free Claude skill catches the words and patterns AI leans on, then rewrites your draft the way a person would.

RaisedWhat’s in the full skill
Seven kinds of AI tells, caught before a donor sees them
Plus three before-and-after rewrites (a donor thank-you, a board update and a year-end appeal) and a step-by-step install guide for Mac and Windows.
Cadence
The rhythm that gives it away
Contrastive reframes, rule-of-three padding and sentences that all run the same length.
Scaffolding
Filler, cut
About 50 openers, transitions and closers like “In today’s fast-paced world” and “At the end of the day.”
Structure
Em dashes and other tells
Em dashes, stacked semicolons, bold inside sentences and bullet salad.
Your voice
Rules that sound like you
A 10-question setup captures your name, your banned words and how you sign off, so every draft fits.
Three modes
Filter, check or fix
It filters as Claude writes, flags problems with /slop-check, or rewrites a draft with /slop-fix.
From Colleen & Scott
Your voice is the whole point.
AI writes in its default voice until someone teaches it yours. The Slop Filter is the fastest way we know to start, and it takes about ten minutes to install.

Implementing AI
AI slop happens when AI sits in the director's chair
Every nonprofit can now make more content than it can read. The teams that sound like themselves keep one job for people: deciding.
Prompts & Templates
The nonprofit brand-voice prompt, copy paste done
One reusable nonprofit brand-voice prompt that teaches any AI how your org sounds, so every draft starts in your voice instead of the tool's default.
Implementing AI
Your first AI system should be your brand voice
Most orgs point their first AI system at a task. The ones that make AI stick start with voice, so everything they build sounds like them. Here is why brand voice comes first, and how to build it in an afternoon.
