What you can sell
Eight ways to package your AI work.
Start with whatever you can ship fastest — a prompt today — and grow into higher-value listings as you go.
Prompts
$5–$19A single, sharp instruction that gets one job done well — the fastest thing to package and list.
e.g. “Best AI tools 2026 finder”
Skills
$9–$29A portable capability, written as a SKILL.md, that an assistant or agent loads when a task calls for it.
e.g. an APA citation checker
Assistants
$12–$39A configured helper for a recurring task — instructions plus context that a buyer drops straight into their model.
e.g. cold-email strategist
Agents
$30–$150Multi-step automation that takes actions and chains tools — among the highest-value things you can list.
e.g. resume + job-search agent
Crews
$30–$150A manager persona routing work across your agents and task prompts — a whole job in one listing.
e.g. customer-support crew
Products
$19–$66A ready-to-run bundle: a persona, skills and an assistant or agent packaged as one purchase.
e.g. a sales-outreach kit
MCP Servers
$12–$49A Model Context Protocol server: a connector that gives a buyer’s AI client live tools and data.
e.g. a connector to a team’s CRM

FAQ
Making money with AI, answered.
Everything sellers ask before listing. Still curious? Read the full seller FAQ, browse the AI agent marketplace, or explore the Sigrix Learn library.
You package something you already know how to make with AI — a prompt, a persona, an assistant, an agent, or a bundle — and list it on the marketplace. Buyers pay once for instant access, and you keep 80% of every sale (85% as a founding seller). There is no audience to build first and no subscription to run; the listing does the selling.
It depends on your price and how many people buy. Use the calculator above to model it. As a grounded reference: one of our sellers earned about $500 in a year selling AI image-generation prompts on another marketplace. On Sigrix you set your own price and keep a larger share, so the same volume earns more — and a single higher-value agent can change the math entirely.
Every kind of listing the marketplace carries, from a single prompt to an agent, a crew or an MCP server. Prompts are the fastest to ship; agents and crews are the highest-value. You can list as many as you like under one account, mixing free and paid to build a catalog and a reputation.
No. Sigrix weighs craft over follower count — a working prompt people would pay for is enough to apply. Prompts and personas need no code at all. Agents are more technical, but they are optional; most sellers start with prompts and personas.
Payouts are sent to your connected account on a regular cycle once you clear the minimum threshold. Sigrix takes its commission automatically at the point of sale, so the figure you see is what lands with you — no invoicing, no chasing.
Yes. There is no exclusivity clause — keep selling wherever you already do. We just ask that your Sigrix storefront gets your best work. Bring your existing catalog over; importing what already sells is the quickest way to start earning here.
Nothing to list. There are no monthly fees and no listing fees — Sigrix only earns when you do, through the per-sale commission. The one running cost a buyer sees is the tokens your prompt or agent uses, which every listing displays up front.
