About
Prostir is a no-code platform for launching custom AI apps without building the backend yourself.
Users upload their knowledge, write plain-English rules, connect tools such as Stripe, HubSpot, Notion, Slack, or custom APIs, then launch one AI app that can work inside ChatGPT, Claude, Cursor, a website, or a web app. Prostir handles the technical layer behind the product: knowledge ingestion, MCP endpoints, tool access, authentication, customer accounts, usage limits, Stripe-backed payments, and deployment.
The product is built for experts, creators, consultants, SaaS teams, course owners, and businesses that have useful knowledge or repeatable workflows and want to turn them into a working AI product. A consultant can package playbooks into a paid AI expert. A course creator can launch a tutor that answers from approved material. A SaaS company can ship a customer support or onboarding assistant trained on its own documentation. An internal team can create a private helper for recurring questions and tasks.
Prostir solves the gap between “this works in ChatGPT” and “customers can actually use and pay for it.” Custom GPTs are limited to one platform and usually leave creators without payments, customer ownership, usage controls, or proper deployment options. Building a custom AI backend from scratch means developers, auth, hosting, tools, APIs, MCP, payments, dashboards, and months of work. Prostir packages that infrastructure into one product flow.
The goal is simple: help people turn knowledge, instructions, and tools into live AI apps faster, with clear control over who can use them, what they can access, how they behave, and how they are monetized.

FAQ
What is Prostir?
Prostir lets non-technical creators build Agents and Skills, configure access, and publish a hosted MCP endpoint. Add supported knowledge, write the rules, then verify each target AI client or configure an eligible website widget or channel separately.
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.
Do I need to know how to code?
You can create an Agent and upload supported files without writing code. Official integrations still require authorization and setup; custom API or MCP connections need a configured endpoint and may require technical review.
How is this different from a Custom GPT in ChatGPT?
A Prostir Agent has a hosted MCP endpoint, owner-controlled access, and optional paid access. Use it only in supported clients you verify; website widgets and other channels are separate eligible configurations, not automatic destinations for the same link.
How do customers actually use my AI?
Choose the delivery path the Agent supports. Install and verify its hosted MCP endpoint in each compatible AI client, or configure an eligible website widget or another channel separately. Availability, authentication, and setup differ by path.
Which AI clients does it work with?
A target client must support the required MCP transport and authentication flow. ChatGPT, Claude, and Cursor can be target clients when their current capabilities and the Agent's access mode match; verify each client before sharing it.
Can I charge in my local currency?
Currency availability depends on the seller's provider account and market. Eligible Stripe Connect accounts can offer one-time payments and subscriptions. Rozetka Pay is for one-time UAH payments in Ukraine. The seller handles tax, refunds, receipts, and customer obligations; Prostir does not route currencies or custody buyer funds.
What happens to my knowledge? Is it private?
Agent knowledge is isolated by owner and Agent. Creators can manage and remove their knowledge, while retention and deletion follow the applicable product and legal policy rather than a universal one-click promise.
Can I try it without paying?
When you sign up, you get Creator free for 7 days, no card needed. You can switch to any self-serve plan during the trial, and the end date stays the same. Add a payment method before that date to continue; otherwise nothing is charged and the subscription stops.
What happens to my customers if I cancel?
Portable ZIP export covers the Agent's author-owned configuration and durable content. It excludes credentials, customer records, conversations, sessions, and payment state, so plan any separate data migration before cancellation; there is no blanket 30-day retention promise.
