Frequently asked questions

Is this really free? What's the catch?

What is 21 Days of AI?

21 Days of AI is a structured course series that builds practical AI skills one day at a time. Each course is built for one profession - marketers, HR teams, freelancers, sales, or entrepreneurs. Every lesson has a concept, a copy-ready prompt, and a focused task that produces something reusable.

Do I need technical skills to start?

No. The courses are designed for professionals who use AI tools at work, not for developers. You only need access to a free AI chat tool like ChatGPT or Claude.

How much time do I need each day?

About 15 minutes. Each day has a short lesson, a prompt to copy, and one focused task you can apply to real work.

Which AI tools do the courses cover?

Lessons work with common AI chat tools including ChatGPT, Claude, and Gemini. You choose the tool - the prompts and techniques transfer across all of them.
