Watch an AI agent answer its first question in 60 seconds

You don't need to understand LangChain, vector databases, or prompt chaining to build a useful AI agent. You need MindStudio and about a minute.

Go to mindstudio.ai and click Sign Up. The free tier gives you 100 runs per month — more than enough to finish this lesson and have room to play.

Once you're in the dashboard, click the big purple + New Agent button in the top right. You'll see three starter templates. Pick Blank Agent — we're going to feel the raw power first, then use templates in later lessons.

You'll land in the workflow canvas. There are three nodes already placed: Input, AI, and Output. That's the whole agent. Click the AI node in the middle. In the right-hand panel, paste this into the Prompt field:

You are a friendly customer support agent for a SaaS company called Helpdesk Hero. A user just sent: {{input}}

Reply in under 3 sentences. If the question is about pricing, mention our plans start at $19/mo. If it's about refunds, say we offer a 14-day no-questions-back refund. Otherwise, answer helpfully. ```

Set the model dropdown to GPT-4o mini (it's free and fast). Hit Save, then click the purple Run button up top.

A test panel slides in. Type: `how much does this cost?` and hit Enter.

In about two seconds, you have a working AI support agent. It read your instructions, understood the intent, and replied in your brand voice. Try another: `can i get my money back?` Watch it cite your 14-day policy.

That's the free tier. You can embed this agent as a chat widget on one site, get 100 messages per month, and that's it. No data sources, no triggers, no Slack, no CRM, no analytics.

The rest of this course is what Pro unlocks — and why the $19/month is the last support tool you'll ever pay for.
