How to Sell Custom GPTs and AI Prompts in 2026
You've built a custom GPT that does one job really well. Or a prompt set that saves you hours each week. "Can you sell GPTs?" is one of the most common questions creators search. Here's how it works in practice.
Can you sell GPTs?
Not directly as a paid link inside ChatGPT: a shared GPT link can be opened by anyone with access, and you can't put a price tag on it there. What you can sell is the work behind it:
- GPT kits: the full instructions, knowledge-file structure, conversation starters and setup notes, so buyers can rebuild the GPT in their own account.
- Prompt packs: tested prompt sets for a specific workflow.
- Agent setups: system prompts, tool configs and workflow docs for AI assistants.
Always check OpenAI's current usage policies and the terms of any model you build for. Don't include content you don't have the rights to, such as copyrighted books dropped in as knowledge files.
What makes a GPT product worth paying for
Free prompts are everywhere. Paid ones need to be clearly better:
- One specific job. "Writes Stripe-ready pricing pages for SaaS" sells; "general assistant" doesn't.
- Tested results. Include example inputs and outputs.
- Complete setup. Instructions, knowledge files (that you own), starters, and a step-by-step rebuild guide.
- Model notes. Say which models you tested with.
- Clear license. Personal use, team use, client use, no reselling.
Package types that sell
| Product | What's in it | Typical buyer |

| Prompt pack | 20–100 tested prompts for one workflow | Freelancers, content teams |
| Agent setup | System prompts, tool definitions, workflow docs | Developers, ops teams |
| Vibe-coding prompts | Prompt templates to scaffold apps with AI coding tools | Indie hackers |

How to price GPT kits and prompt packs
- Price by outcome, not word count. A kit that produces client-ready reports is worth more than 500 generic prompts.
- Start low, then raise. Early reviews matter more than early margin.
- Bundle. A GPT kit plus a matching prompt pack beats two separate small sales.
- Remember VAT. On Botnexio, the price buyers see is in EUR and includes VAT; your share is calculated on the net price.
Where to sell: marketplace vs. own shop
Own shop: full control, but you handle payments, VAT receipts, delivery and traffic yourself.
Prompt-only marketplaces like PromptBase focus on single prompts.
Botnexio is one marketplace for Discord bots, GPTs and vibe-coding templates. Payments run via Stripe, products are reviewed before they go live, and buyers can find your GPT kit next to bots and code templates.
Fees and payouts on Botnexio
You connect a Stripe Express account on the creator page. Standard: you keep 85% of the net price (excl. VAT), less Stripe fees.
Example from the creator page: a €29 sale to a buyer in Germany (incl. 19% VAT) → net €24.37 → your share €20.71, minus Stripe fees.
Step by step: list your first GPT kit
- Pick one use case and write it as a one-line promise.
- Export everything a buyer needs: instructions, knowledge-file templates, starters.
- Write the rebuild guide: numbered steps from "open GPT builder" to "first result".
- Add 3–5 examples of real inputs and outputs.
- Connect Stripe via Creator onboarding.
- Upload with name, category, EUR price and description; see the creator guide.
- Pass review and go live.
Listing checklist
- Title says the job: "Custom GPT Kit for SaaS Onboarding Emails".
- First line says the result.
- List exactly what's in the ZIP.
- State which models you tested.
- State the license.
- No promises you can't back up ("10x revenue").
