What can you sell?

Sell the knowledge only a specialist like you has.

An AI skill is not a course, a template, or a prompt pack. It is your years of experience packaged for an agent: what you notice, what you ignore, what you check, and the decision rules a beginner would not know to write down.

SEO

Your ranking sense

The issues you notice before a generic audit tool does: indexing risk, weak pages, internal-link gaps, and what to fix first.

Development

Your debugging taste

The failure modes, edge cases, and architectural calls you recognize because you have seen the same class of bug before.

How it works

Turn one piece of expertise into a paid AI skill.

Start with one thing you know unusually well. Write the judgment, examples, checks, and edge cases an agent needs to use that skill well.

The format changed

AI changed how expertise gets used.

People do not need another ebook, course, or template. They need their agent to make better calls while work is happening. Capabase lets you sell the part of your expertise an agent can actually use.

Old way

Sell content someone has to study.

FAQ

Questions a seller should ask first.

The short version: sell one concrete piece of specialist judgment. Keep it useful, installable, and narrow enough that a buyer knows when to run it.

What is an AI skill?

An installable package that teaches an agent how to handle one specific job. It can include workflows, examples, checks, edge cases, and decision rules an agent can reuse.

What kind of knowledge can I sell?

Any specialist knowledge that can be used on a computer: SEO audits, code review, research, app growth, legal ops, finance admin, design critique, clinical admin, and more.

Start with one skill

Put one piece of your expertise on the marketplace.

Pick a thing you already make better than most people. Package the workflows, learnings, examples, edge cases, and judgment behind it. Capabase gives it a listing, checkout, delivery, and a place buyers can find it.

Marketing

Your growth judgment

The ad account reads, landing page notes, tracking doubts, audience calls, and launch instincts that usually stay in your head.

Research

Your research filter

The sources worth trusting, the weak evidence to ignore, and the comparison structure that turns scattered notes into a usable brief.

Operations

Your process judgment

The policy checks, admin edge cases, vendor reads, handoff rules, and repeatable decisions that keep specialist work moving.

Creative

Your critique taste

The design, content, positioning, and brand review calls that separate a useful critique from a list of generic suggestions.

If your expertise changes the answer, it can become a skill.

Start with one thing you know better than most people in your field. Capabase turns that knowledge into a listing buyers can find, buy, and install.

    Do I need to package everything I know?

    No. Start with one useful slice. One recurring decision, one review process, one checklist, one type of analysis, or one thing clients already ask you to do.

    How is this different from a prompt pack?

    A prompt gives a model a one-time instruction. A skill gives an agent reusable specialist context: what to check, what to ignore, what examples matter, and how to make the call.

    How to use a skill?

    Buy it, install it into your agent, and run it when you need that specialist skill. A good AI skill makes the agent better at one concrete job.

    What does Capabase review?

    We review submitted skill files for hardcoded secrets, suspicious tool use, unsafe instructions, and files that should not ship to buyers.

    How do creators get paid?

    You set the price for your skill. Capabase handles checkout and delivery, and creators keep 85% of the product sale price before taxes and marketplace adjustments.
