No-Code AI Automation Tool for Small Businesses

I am looking for a no-code solution to create a smart AI automation tool that helps small businesses save time and boost sales. The app should include the following features:

- A user-friendly interface
- Integration with WhatsApp for auto-replies and customer communication
- Ability to capture customer details
- Send reminders to ensure no sales are missed

The primary goal is to provide this tool for free as a way to promote my services. The analytics feature is optional but would be a nice addition if feasible within the budget.

Ideal Skills and Experience:
- Experience with no-code platforms like make.com or similar tools
- Familiarity with drag-and-drop AI agents or LLM solutions
- Strong understanding of integrating messaging platforms like WhatsApp
