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.
