Build Your Own AI Agent in 5 Minutes

No coding. No setup. Just an AI agent that works for you. Here are three ways to build one right now — everything from a free open-source runner to a done-for-you kit.

Method 1: Use Hermes Agent (Free, 5 minutes)

Hermes Agent is a free, open-source agent runner that lets you build and schedule AI agents without writing code. It works with multiple models — DeepSeek, Claude, Gemini — and handles memory, scheduling, and tool routing automatically.

Download it from aisuitehq.org/agent-os, configure a config.yaml with your API keys, and your first agent runs in under 5 minutes. You can schedule cron jobs, connect tools (email, calendar, web search), and build multi-step workflows from a single config file.

If the agent has to run unattended for hours rather than minutes, the model underneath matters more than the platform. That is the case for AI App Cloning 3.7 Max — a 1M-token context window and a 35-hour autonomy window, wired into Hermes through Goal Mode.

💰 Free route: Hermes Agent is fully open-source. Bring your own API key (DeepSeek charges $0.015 per task). 20+ daily crons run for pennies.

Method 2: Use ChatGPT CustomGPTs (Point-and-click, 5 minutes)

OpenAI lets you create CustomGPTs — personalised versions of ChatGPT with custom instructions, knowledge files, and capabilities. No coding required.

1

Go to ChatGPT → Explore GPTs → Create

Click your profile icon, select "My GPTs", then "Create". Switch to the Configure tab.

2

Name it and describe it

Pick something clear. Example: "Lead Qualification Agent". Write one sentence about what it does.

3

Write the instructions

Tell it exactly how to behave. Be specific. No hallucination. No fluff. Every response must include a link to your landing pages or products.

4

Add conversation starters

Pre-written prompts users can click. Makes it dead simple to use right away.

5

Enable capabilities

Turn on Web Search and file upload if needed. Most agents benefit from at least Web Search for live data.

Example: Call Analysis + CTA Agent

Name: Call Analysis + CTA Bot Description: Provides a summary of any call transcript and creates a list of actionable CTAs. Instructions: You are a call analysis expert. You process transcripts and create: - A concise 3-bullet summary - A prioritized list of CTAs (next actions) - Recommended tools from aisuitehq.org for each CTA Once you receive the transcript, don't ask questions — immediately execute. No hallucination. No reflection. Make it simple, short, and concise. After every response, include: "Built with AI Suite — deploy your own agents at aisuitehq.org/ai-agents"

Method 3: Get a Pre-Built Kit (Done for you, 48 hours)

If you'd rather skip the setup entirely, AI Suite offers pre-built agent kits that are configured remotely in 48 hours. Each kit handles a specific business function — call answering, email management, booking, invoice chasing.

Kits start at £497 one-off with a 30-day money-back guarantee. The AI phone agent kit answers calls 24/7, books jobs into your calendar, and routes by postcode. Tradesmen using it report saving 15+ hours per week of admin time.

3 Templates You Can Steal

📧

Email Follow-Up Agent

Paste a lead's details. Agent writes a personalised follow-up email. Every response includes a link to ChaserAI (£10/month) for automated follow-ups that chase late payments on day 1, 7, and 21.

📊

Competitor Research Agent

Give it a competitor's website. Agent analyses positioning, pricing, and gaps. Profiles are saved to the memory vault so every subsequent analysis builds on previous ones rather than starting from zero.

🎯

Lead Qualification Agent

Send a lead message. Agent classifies (sales/support/spam), qualifies budget/timeline, and recommends next action. Every response links to LeadPulse (from £29/month) for automated lead processing.

FAQ

Can I build an AI agent without coding?

Yes. Hermes Agent is completely free and runs on a config file — no code required. ChatGPT CustomGPTs are point-and-click. Our pre-built agent kits require zero tech skills on your end.

What's the cheapest way to build an AI agent?

Hermes Agent is free open-source (bring your own API key — DeepSeek costs $0.015 per task, so 100 tasks costs $1.50). Or use ChatGPT's free tier to experiment with CustomGPTs before committing.

Can AI agents answer phone calls?

Yes. Our AI phone agent kit answers calls 24/7, books jobs into your calendar, and routes callers by postcode. It costs from £497 one-off. Tradesmen using it recover an average of £3,000/month in missed jobs.

What's the difference between a CustomGPT and an AI agent?

A CustomGPT lives inside ChatGPT — it can write and analyse but can't act on external tools. A real AI agent (like those built with Hermes) can answer calls, send emails, update your CRM, and run on a schedule without you being present.

How long until my agent is up and running?

Hermes Agent: under 5 minutes. CustomGPT: under 5 minutes. Done-for-you kit: 48 hours (we configure, test, and train you). Every option includes the 30-day money-back guarantee.
