What’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.

Vocabulary

### The words AI leans on

About 75 words like leverage, robust and transformative, each with a plain swap.

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.

Two co-founders, 11+ years inside nonprofit fundraising, 100+ orgs served, $200M+ raised.

### [Your first AI system should be your brand voice](https://ifpossible.ai/articles/first-ai-system-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.
