Yes. No trial, no limits. If you want your own voice card, more platforms, a content calendar and images, there's a paid full version.

How is this different from asking Claude to "sound human"?

A plain prompt changes the wording but keeps the AI habits. This skill starts from one real detail you give it, removes common AI patterns and rewrites them, and gives you two versions with different angles. If you give it nothing specific, it asks one question instead of making something up.

Will it make up numbers or stories to make my post better?

No. It never invents experiences, clients, numbers or testimonials, even if you ask. Where a real detail is missing, it leaves a short placeholder for you to fill in.

Which AI tools does it work with?

It was built and tested in Claude. It follows the standard SKILL.md format, so other agents that support skills should be able to load it, but they haven't been tested.

What's the difference from the full version?

The free version covers LinkedIn and X. The full version adds a voice card from your own posts, 70+ AI patterns, five more platforms, repurposing, a content calendar and optional image graphics.

The story

In August we started fixing flat tires while you wait. About 15 minutes, then you ride off.

That month we did 40 of them. In September we did 212.

[one real moment: e.g. a courier who came in on their lunch break]

If your company has bikes on the road, a flat shouldn't cost a rider half a day. We're in Graz, open [days and hours].

The claim

A flat tire is a 15-minute job. It shouldn't take a bike out of service for days.

So in August we started doing flat repairs while you wait. 40 in the first month. 212 in September.

If you look after bikes for a team in Graz, send me a message. I'm happy to talk about how we'd handle your fleet.

#Graz #BikeFleet

Fill in: a real moment from the shop, and your opening hours.

We closed the deal in record time.

Complexity is usually just a lack of courage to pick what matters.


## The Claim Angle
```text
If your sales deck is 50 slides long, you aren't selling. You're hiding.

We spent three months fighting to get our deck down to 5 slides. The result? Our latest discovery call turned into a closed deal faster than any lead we tracked this year.

Five slides forces you to own the narrative instead of reading off a screen.

Next steps

Replace "record time" in the first draft with the actual number of days it took to close.
Post the "Story Angle" on a Tuesday morning for maximum LinkedIn reach.
Use the first line of the "Claim Angle" as a standalone post on X.

Connects securely to your tools. The creator never sees your data.
