I had AI draft a WeChat Moments post. Output: "OMG sooo good!"—I cringed so hard my face went red.

The Moment I Wanted to Disappear

Last week I tried to be lazy and had AI brainstorm some WeChat article titles. Every single one came back as "OMG guys! You won't BELIEVE this!" I couldn't even bring myself to look at what it produced.

This Tool Is Called Claudette—Who's Using It

Basically, it slaps a "no-marketing-speak filter" onto Claude (the Anthropic AI). Before you talk to it, you preload instructions telling it to chill out, drop the exclamation marks, kill that hype-man tone.

I made this mistake before: I assumed AI defaults to that over-the-top voice. It doesn't—you just haven't set the instructions right.

Ailin, who runs a Xiaohongshu (Little Red Book) account, told me she spends 20 fewer minutes editing each post since installing it. Her exact words: "It finally doesn't sound like a hype-man anymore."

What It Costs to Replicate Today

Money: $0, free
Time: 10 minutes
Tech barrier: copy-paste level, no code needed
First step: open Claude.ai web → click your avatar bottom-left → find "Profile" → locate "Custom Instructions" → paste the English prompt from the Claudette project

Too much hassle? You can also paste that prompt manually at the start of each new chat—same result.

How Three Types of People Use It

Just starting out, no clients yet
No rush to try it. Build the skill of writing like a human yourself first—that's worth more than any tool. But if friends have said "your recent posts don't sound like you," spend the 10 minutes and install it.

Have 1-2 steady clients
I'd strongly recommend installing. The more your deliverables sound like "a normal person wrote them," the less clients will haggle on price. But remember—not everyone needs this. If your client actually loves the hype-marketing style, skip it.

Scaling up, posting 10+ pieces a day
Install it. Saves 5 minutes per piece, an hour a day. But also realize—once AI writes smoothly, clients can use AI too. What you'll compete on isn't "fast writing" anymore, it's "right writing." This tool fixes the first, not the second.
