Kopai

Kopai is a no-code platform where experts turn their knowledge into an AI agent published on the Kopai marketplace, priced per message instead of per hour. Upload your expertise, publish in minutes with no code, and let people pay for instant answers instead of booking your calendar. Creators keep 70% of everything their agent earns; Kopai handles discovery, payments, and infrastructure.

It addresses a clear problem: an expert spends years building knowledge they can only sell one hour at a time, hitting a hard ceiling the moment their calendar runs out. Kopai provides real infrastructure rather than a simple prompt wrapper: built-in evaluation testing, encrypted knowledge bases, and multi-agent orchestration. You can also export your agent, or import any other agent from the marketplace, straight into your own site.

Every answer comes back sourced, not guessed, pulled from PDFs, guides, and FAQs the expert uploads. Building is entirely free; monetization happens when agents sell on the marketplace, with a granular, transparent ledger showing exactly where the money went.
