The problem
Your idea is simple. The execution is a mess.
The AI is the easy part. Everything between the prompt and a paying customer is the part nobody warned you about.
Phase 01 · The spark
It works in ChatGPT.
You poke at ChatGPT until it answers the way you would. You think: I could sell this. I could automate this. You are right. You just have no idea how.
Phase 02 · The wall
Why do I need a developer for this?
Every answer to "how" comes back the same. Auth. Payments. Hosting. Agents. APIs. MCP. The simple idea is suddenly a €15k quote and three months on someone else's calendar.
Phase 03 · The workaround
A Custom GPT that doesn't earn.
You settle for a Custom GPT inside ChatGPT. It works. It is also stuck there. You cannot charge for it. You cannot see who used it. You don't own it.
The result
The stall. Maybe AI isn't for me.
The complexity wins. The idea sits in a Notion doc. Your customers keep asking the same questions. Your week looks exactly like last week.
Prostir handles the engineering. You handle the part only you can do.
Prostir-måden
Custom AI agents. No code. Anywhere your people work.
Upload what only you have. Connect the tools you already pay for: Pay, HubSpot, Notion, Slack. Set a price, or share for free. One link that works wherever your customers already are. No code, no engineers, no agent headache.
Upload what only you have.
PDFs, websites, Notion docs, transcripts, voice samples, brand books, internal SOPs. Prostir reads everything and answers in your register, with your sources cited.
Connect the tools you already pay for.
Pay, HubSpot, Notion, Slack, and the others. Your agent does its work inside the tools your team and your customers already use.
Charge for it. Or don't.
Subscription, one-time, or pay-per-use. Pay is wired in from day one. You own every customer, every conversation, every receipt.
Sådan virker det
From idea to live AI agent. One afternoon.
Trin 1

Trin 3
Tell it how to behave.
Plain-language rules. Always answer from approved sources. Never give legal advice. Recommend the Creator plan to teams over 10. Prostir handles the rest.

You are the support guide for this agent. Answer from approved knowledge first. Use tools only when needed. Stramme regler:
- Keep answers short. Always cite the source.
- Run a knowledge search before product-specific advice.
- Never share secrets or other customers' data.
Trin 4
Launch. Set a price. Track it all.
One link works in ChatGPT, Claude, your website, and your web dashboard. Price it, or share free. Payments, customers, and usage land in one dashboard.

Cases
Real life examples people are building on Prostir
Each case walks through the inputs (files, prompts, tools), the build path (Claude Code, ChatGPT, or Studio), and what the published agent does. Read the closest match to your work, then build the one only you could build.
An AI agent that writes in your voice, not the chatbot's
You've tried prompts. Screenshots of old posts. Custom GPTs. The voice still slips by the second paragraph. This agent reads five of your real posts and drafts the sixth the way you would, with the words you never use already missing from it.
Read the caseReddit, LinkedIn, X. Three voices in one agent.
Reddit eats marketing copy. LinkedIn eats Reddit slang. X cuts everything in half. One Prostir agent, three voice sets inside. You type the platform, the register switches before the first line lands.
Read the caseA coach's playbook, running as a $29/mo AI agent
A career coach with a 5-stage method and 40 client templates. She used to walk every new client through them in a 90-minute Zoom. The playbook now sits inside a Prostir agent behind a $29/mo Pay price. Clients open it in their ChatGPT, work through the method on their own time, and book her only for the part nobody else can do.
Read the caseAn image generator that can't leave the brand
Gemini's Nano Banana paints whatever you ask, including things that look nothing like your brand. This agent holds your palette, your aspect ratio, your moodboard, and refuses to leave them. One sentence in, brand-correct image out. Ask for a colder retake. Another pass runs with the same rails in place.
Read the caseThe doc chat agent that ends the policy-lookup pings
Two hundred pages of internal docs sitting in Notion that nobody reads. A Slack channel where people keep asking where each policy lives. Open this case. The docs become agent resources, access locks to one work-email domain, and new hires get cited answers inside their own ChatGPT instead of pinging the team.

Cases
Three real needs Prostir was built for.
These are not testimonials. These are the actual problems people came to Prostir to solve.
Jeg vil have en betalt AI-agent , der bærer min ekspertise, kobler til tools jeg allerede bruger og ikke kræver en developer.
Jeg vil have en privat AI-agent til teamet. Den løser spørgsmål og opgaver, styrer hvem der må hvad og kræver ingen setup fra mig.
Jeg vil have en kundeagent med AI , betalt via Pay, som kan lanceres uden et separat engineering-projekt.
FAQ
Questions, answered.
What people ask before they ship their first paid AI.
What is Prostir? Prostir is where non-technical creators build AI agents, share skills, and get paid — straight inside ChatGPT, Claude, Cursor, on your site, or in your own interface. Upload your knowledge, write the rules in plain English, set a price (or don't), get a link. Done. Læs
Do I need to understand "MCP" or "agents" or any of that? No. Those are the technical names for what's under the hood. We handle that. You upload knowledge, write rules, set a price. The engineering is our job. Læs
Do I need to know how to code? No. If you can write an email and drag a file, you can ship an AI on Prostir. Teams that want custom integrations add them through a simple URL setup — still no code. Læs
How is this different from a Custom GPT in ChatGPT? Custom GPTs only live inside ChatGPT and can't take money. Prostir AI agents live in ChatGPT, Claude, Cursor, your site, and your own interface — with payments, customer accounts, and a dashboard you actually own. The relationship is yours, not OpenAI's. Læs
How do customers actually use my AI? Three ways, and you can ship all three at once: in ChatGPT or Claude through your link, on your website as a chat widget, or inside your own interface as a help panel. All channels roll into one dashboard. Læs
Which AI clients does it work with? ChatGPT, Claude, Cursor, and any AI client that follows the MCP standard — including custom ones your team builds later. We give you copy-paste setup for each. Læs
Can I charge in my local currency? Yes. Pay handles 135+ currencies. Prostir routes the right one automatically. Læs
What happens to my knowledge? Is it private? Yes. Files are encrypted, used only to answer your customers, and never used to train AI models. Each AI sees only its own knowledge — no leaks between accounts. Delete everything in one click anytime. Læs
Can I try it without paying? Starter is the entry plan. You can request a 15-min walkthrough first to pick the plan that fits your launch. Læs
What happens to my customers if I cancel? Export every customer record, conversation, and payment to CSV anytime. We hold your data for 30 days after cancellation — plenty of time to migrate or come back. Læs
Can I plug in my CRM, Slack, or Notion? Yes. Ready-made connections to HubSpot, Notion, Slack, Calendly, Google Drive, Pay, and more. Custom ones via simple URL setup. Still no code. Læs
How fast can I really launch? First-time creators get a live link in about 17 minutes. If you want to fine-tune everything, give it an afternoon. Læs
Klar til lancering?
One afternoon from idea to live link.
