Prostir — Build the AI agent only you could build.

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.

Stuck in ChatGPT
No payments
No customer data

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-sättet

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.

Så funkar det

From idea to live AI agent. One afternoon.

Steg 1

Steg 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.

Systeminstruktioner

 You are the support guide for this agent. Answer from approved knowledge first. Use tools only when needed. Strikta regler: Keep answers short. Always cite the source.
Run a knowledge search before product-specific advice.
Never share secrets or other customers' data.
  

Steg 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.

Case studies

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.

CASE // 01

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.

Låg setup

Jag vill ha en betald AI-agent som bär min expertis, kopplar till tools jag redan använder och inte kräver en developer.

02 Intern hjälp

Privat

Jag vill ha en privat AI-agent för teamet. Den löser frågor och uppgifter, styr vem som får göra vad och kräver ingen setup från mig.

03 Kundhjälp

Redo att skicka

Jag vill ha en kundriktad AI-agent , betald via Pay, som kan skickas utan ett 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. Läs

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. Läs

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. Läs

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. Läs

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. Läs

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. Läs

Can I charge in my local currency? Yes. Pay handles 135+ currencies. Prostir routes the right one automatically. Läs

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. Läs

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. Läs

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. Läs

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. Läs

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. Läs

Redo att lansera?

One afternoon from idea to live link.

Upload what only you have. Write the rules in plain language. Open the link in ChatGPT, Claude, or your site. Ship the agent only you could ship.
