TLDR: A file is a one-time sale of everything. Once your Skill is a document in someone's folder, it can be forwarded, copied and reposted, and your subscription is a request. Distribution through a connector flips that: the Skill stays on the server, the subscriber gets access, and access is yours to give and take. You can see who has it, add a hundred people from a CSV, remove one person in a click, and change the Skill once for everyone. That is the difference between selling a product and running one.

Key Takeaways

  • Files end your control at delivery; access keeps it.
  • With a connector, updating a Skill once updates it for every subscriber on their next call.
  • A subscriber list you can see is a business; a folder of sent emails is a hope.
  • Stacks let you sell sets, tiers and bundles without building anything.
  • Removal is one click and takes effect on the next call.
  • Your assistant choice and your subscriber's assistant choice do not have to match.

What a file really is

When you email a Skill as a document, you have shipped the whole method and all your leverage in one go. The recipient can forward it. They can paste it into any assistant. They can keep using it after they stop paying. None of that is malice; it is what files are for.

What access is

Access means the Skill stays where you put it and the subscriber is allowed to use it. The connector delivers the Skill to their assistant on each call (Password mode) or runs it for them (IP mode). Either way, the Skill is never a thing in their folder. Stop the access and the next call is refused. In Password mode a chat that already has the text keeps it until that chat ends; in IP mode there is nothing to keep.

Updating once

Fix a step in a Skill and every subscriber in the Stack gets the fix on their next call, in a new chat for Password mode. No "please download version 3" email, no three versions in the wild.

Selling sets without building a store

Stacks are sets. A Starter Stack with three Skills and a Pro Stack with ten is two grants, not two products to build. Move a subscriber from one Stack to the other when they upgrade.

The list is the asset

Your creator dashboard shows who is in and what they reach, with reports on sign-ins and Skill usage. That list is what you own when a platform changes its mind, as OpenAI is doing with GPTs on December 11.

Add a hundred, remove one

Adding subscribers is a manual entry or a CSV upload; on the larger plans your billing system can do it through webhooks. Removing one is a click. Both take effect on the subscriber's next call.

Start with the Skill you send most often

Pick the Skill you email most. Put it behind the connector. Send the connection steps instead of the file next time. Watch the difference in your inbox.
