In the race to build AI agents, Postman’s AI Agent Builder stands out as a powerful tool for developers. It makes it easy to connect APIs, test workflows, and prototype language model–driven logic.

But building a workflow and launching a product are two very different things.

Postman wasn’t built for creators who want to brand their agent, add long-term memory, or turn it into a paid service. It’s an internal development tool, not a platform for monetization.

That’s where Knolli comes in.

Knolli is a no-code co-pilot builder that helps users create AI assistants they can embed, brand, and charge for. Knolli offers everything needed to turn a working agent into a polished, public-facing product for educators, consultants, and SaaS teams building client-facing tools.

If you’ve outgrown Postman’s developer sandbox, Knolli is where you go to launch.

What is Postman AI Agent Builder?

Postman AI Agent Builder is part of Postman’s popular API toolset. It allows developers to create AI agents by chaining API calls and using large language models (LLMs) to process information, make decisions, and return responses.

Core Features:

  • Visual builder for chaining APIs

  • Support for LLMs like GPT-4

  • Prompt-based instructions and tools

  • Access to 18,000+ public APIs

Postman is designed for developers. It's powerful if you know how to work with APIs, but not built for people who want to monetize or deploy their agents for real users.
