No-code agent creation
Describe an agent in plain English the way you would brief a new hire, then refine the instructions through chat instead of writing code or prompt templates.
Kopai
Kopai is a web-based marketplace and builder for specialized AI agents. It helps creators build agents from plain-English instructions, ground them in documents, publish them to a marketplace, and earn on a usage-based model.
What Kopai is
Kopai is a marketplace and builder for specialized AI agents. It is positioned for people who want to turn domain knowledge into an agent, publish it, and let buyers find it by niche.
The product emphasizes a plain-English workflow: describe what the agent should do, add supporting documents, test it in chat, and publish when ready. On the marketplace side, agents can be discovered on their own pages, reviewed, and priced per message rather than as a flat subscription.
Core capabilities
Document grounding and citations
Upload PDFs, guides, manuals, and FAQs, then have Kopai chunk and index them so responses can be grounded in your own material with citations.
Model switching
Pick from supported model options shown in the product pages, including GPT, Claude, and Gemini, and switch engines without rewriting your instructions.
Marketplace publishing
Publish an agent to its own marketplace page, or keep it private while you test and refine it before going public.
File and interface outputs
Agents can generate Word, Excel, or PDF files, and the page shows that charts and tables can render live in a sandbox.
Agent-specific capabilities
Some agent listings show extra capabilities such as Knowledge Base or Web Search, while others are standard conversation only, indicating capability sets vary by agent.
Ways people use Kopai
Create a document-grounded internal assistant
A compliance, policy, or operations expert can upload internal handbooks, manuals, or FAQs and build an agent that answers questions from those materials with citations.
Publish a niche expert agent
A creator can describe a niche service or expertise area in plain English, test the agent privately, and then publish it to a marketplace page for buyers to discover.
Support course-specific study workflows
A student or educator can build a course companion that explains concepts from class materials and reviews drafts for what is missing, as shown by the HCI Legend listing.
Route requests through specialist subagents
A travel planner can build an agent that handles a request, recalls relevant context, delegates to specialist subagents, and returns one consolidated answer, as shown by Trip Architect.
Generate files and structured deliverables
Teams that need deliverables can ask an agent to produce reports or spreadsheet outputs that are saved as real files rather than plain text alone.

FAQ
How do you create an agent on Kopai?
Kopai is set up so you can describe the agent in plain English, add documents such as PDFs, guides, manuals, or FAQs, and then test it in chat before publishing. The source does not show a separate technical setup flow beyond that.
Can you test or keep an agent private before publishing?
Yes. The site says you can chat with the agent yourself first, tweak the instructions, and either publish it or keep it private while you refine it.
Do all Kopai agents have the same capabilities?
Yes. The marketplace pages show agent capabilities such as Knowledge Base and Web Search on some listings, while others show standard conversation only. The available tools depend on the individual agent.
Can an agent be used on a website outside the Kopai marketplace?
Kopai says agents can be embedded on your own site with a script tag and that there is no lock-in. The public pages do not show any other deployment methods in detail.
What does Kopai charge?
The pricing page rendered in the source does not show a detailed plan table. It does show that Kopai is free to start and that creators earn on a usage-based model rather than a flat subscription.
