Sold as a ZIP
One payment. Then it's theirs.
- They pay once, whatever you add later
- A refund doesn't take the files back
- Every update means a new ZIP to send
- One upload to a Discord and it's free
For Claude Skill creators
What stops your first buyer from posting your Skill for free? Nothing, if you sell the ZIP.
Sell access to your Skill, not the files.
Buyers use it in Claude, ChatGPT or Cursor, or right in the browser. They never get your SKILL.md.
Charge once or monthly. Access ends when they stop paying, and every update reaches all of them. No cut of your sales.

The one-time-sale treadmill
$15 once, or $15 a month
from the same buyer?
A ZIP sells once. Access can bill every month, because they keep using it and you keep improving it.
Sold as access
Paid for as long as it's used.
- Monthly, yearly or one-time: your choice
- A refund or cancellation ends access
- Publish once and everyone has the new version
- No files to pass around
What a buyer sees
They get the answer.
You keep the SKILL.md.
An example: an SEO brief Skill, sold as access.
1 · Your Skill
- SKILL.md your instructions
- references/serp-checklist.md reference
- references/brief-template.md reference
- scripts/outline.py script
Stays on our servers. Buyers never download it.
2 · What a buyer types
Brief for “best CRM for dentists”. We sell practice software to dental clinics.
In their own Claude
3 · What they get back
Intent: comparison. Searchers want a shortlist with prices, not a guide to CRMs.
The angle the top results miss: insurance billing and patient reminders. Plus a 7-part outline and 5 questions to answer.
SEO Brief Builder v2.3They see the brief. They never see your SKILL.md, references or scripts.
Where your buyers are
One Skill.
Every app your buyers use.
Some of your buyers live in Claude, some in ChatGPT, some in Cursor. They all sign in with the email they bought with.
Claude
Any plan, including Free. One click opens the setup.
ChatGPT
Plus or Pro, with developer mode switched on in settings.
Cursor
Any plan.
The browser
No AI app needed. They sign in and use it on your page.
For Skills you keep in a repo
Keep it in GitHub.
Every push can reach every buyer.
Connect our GitHub app and tick one or several Skill folders. A public repo works from its link.
1 · PushYou push to your repo
Same repo, same workflow. Nothing to export.
2 · CheckWe try the new version
On the example you saved, against the answer you marked right.
3 · PublishIt goes on sale
By itself if you switch that on and the answer still holds. Otherwise we email you why it's waiting.
4 · ReachEvery buyer has it
Their next run uses the new version. No ZIP, no reinstall.
Each commit gets a status in GitHub: checking, ready, on sale, or what went wrong.
What we do, and what we don't
We don't bring you buyers.
We make each one worth more.
Finding buyers is still your job: your audience, your store, your Gumroad page. We handle everything after they pay.
We do
- ✓Bill monthly, yearly or once, through your own Stripe
- ✓End access when a buyer cancels or gets a full refund
- ✓Put every buyer on your latest version
- ✓Run your Skill in Claude, ChatGPT, Cursor and the browser
- ✓Host your store on your own domain
We don't
- –List you in a marketplace next to thousands of others
- –Take a cut of your sales (Stripe's fees still apply)
- –Set your price or change your rules
- –Own your customer list

Before you switch
What a skeptical
seller asks.
Can a buyer get my SKILL.md?
No. They get answers. Your files stay on our servers, and the Skill is told not to reveal its instructions. A good answer can still show parts of how it works, the same as any useful tool.
Can a buyer share their login with friends?
Access is tied to the email they bought with, and you can switch anyone's access off.
Does it work in ChatGPT?
Yes, on ChatGPT Plus or Pro with developer mode switched on. Claude works on any plan, including Free, and so does Cursor. Anyone can also use it in the browser.
I already sell on Gumroad. Can those buyers get access?
Yes. Give access by email, import a CSV of past buyers, or use our API with Zapier so new buyers get access automatically. Or sell from your own store page here, through your Stripe.
What happens on a refund or cancellation?
When a subscription ends, so does access. A full refund or chargeback ends it too. A failed payment pauses access until it's paid. A partial refund doesn't change access.
What about my scripts and reference files?
They come with the Skill and run on our side. Test it on real examples before you sell, to check everything your Skill uses works.
What if one buyer runs it a lot?
Every answer counts as one run. Past the 200 included each month, each extra run costs $0.10. We email you at 80% and 100%.
Do you take a cut of my sales?
No. You pay a flat $29 a month and keep your sales. Stripe's processing fees still apply.
You built the Skill.
Stop selling the file.
