About the marketplace
What is the Sigrix AI agent marketplace?
Sigrix is a dedicated marketplace for AI agents, prompts, personas, skills, and assistants from independent creators. Every listing declares the AI model it runs on (OpenAI, Anthropic, Google), the inputs it expects, the outputs you get, and an estimated token cost — so you can compare AI agents on transparent specs rather than marketing copy.
New to the differences between a prompt, a skill, an assistant, and a full agent? Start with our AI building blocks guide in the Sigrix Learn library — it explains the spectrum from a single instruction all the way to fully autonomous agents, and how each one is priced.
Frequently asked questions
Is there a marketplace for AI agents?
Yes — Sigrix is a dedicated marketplace for AI agents, assistants, prompts, personas, and skills from independent creators. Every listing shows what it does, which AI model it runs on, the token cost estimate, and verified seller reviews so you can compare options before you buy.
What is an AI agent marketplace?
An AI agent marketplace is an online catalog where buyers compare and purchase ready-to-use AI agents — software that performs multi-step tasks on your behalf — alongside the prompts, personas, and assistants that support them. Sigrix curates each listing for clarity, safety, and completeness before it appears in the catalog.
How do I evaluate an AI agent before buying it on Sigrix?
Open any listing to see the agent's described task, supported AI models (OpenAI, Anthropic, Google), required inputs, sample outputs, the token cost estimate, and verified buyer reviews. Read our Learn library for guides on comparing AI agents and understanding token pricing before you purchase.
Can I hire AI agents like freelancers on Sigrix?
Sigrix sells productized AI agents you can buy once and reuse — closer to a software marketplace than a freelance hire. Each agent is built and maintained by an independent creator, so you get instant access without recurring fees on top of your existing AI provider bills.
What types of AI agents can I find on the Sigrix marketplace?
Sigrix categorizes listings into five building blocks: prompts, personas, skills, assistants, and full agents — plus product bundles that combine them. Browse by use case (sales, customer support, marketing, BPM, e-commerce, research, writing, analytics) or filter by AI model and price.
How is the Sigrix AI agent marketplace different from app stores?
App stores sell apps you install; Sigrix sells AI building blocks you compose. Each listing declares the LLM it runs on, the inputs it expects, and the outputs you get — so technical and non-technical buyers can compare AI agents on transparent specs rather than marketing copy.
