Agent Selector
Crafted with Claude Opus

Describe it. We build it.

Describe the AI agent you want in plain English. Get a rigorous blueprint — least-privilege tools, explicit guardrails, an autonomy level, runnable code, and behavior tests. Not just a prompt: interviewed, guardrailed, and behavior-tested. No coding required.

Describe it

Tell us what you want your agent to do, in plain English. No jargon.

We design it — properly

Not just a prompt: one clear job, least-privilege tools, explicit guardrails, an autonomy level, and runnable code.

Test & ship

It comes with behavior tests — including out-of-scope and guardrail checks — then export or deploy it.

Frequently asked questions

Do I need to know how to code?

No. Describe what you want in plain language and we generate the plan plus the code. Developers can export and extend it; everyone else can test it in the sandbox.

What does the sandbox preview do?

It lets you chat with a working version of your agent using safe demo tools (tasks, email drafts, calculations). It never touches your real accounts — connecting real apps comes later in the hosted Run pillar.

Is it really my agent?

Yes. Export a complete, runnable project (code + README + env template) and run it on your own machine or server, with your own key. You're never locked in.

How is this different from ChatGPT?

We recommend real, vetted tools from our directory (not hallucinated ones), give you a concrete build plan and code, and are honest about what won't work — grounded in Agent Selector's catalog.
