AI Certificate in 28 Days
15 minutes a day. 26 tools, one capstone, one certificate.
Especially if you’re over 40.
This course is written for working professionals who’ve watched the AI wave from a distance
and want a guided, low-stakes way in. No coding. No jargon that isn’t defined on the spot.
Every day is one tool, one walkthrough, and one hands-on task you’ll actually use.

What you will do
Each day is one AI tool. You’ll read a short “why this matters,” walk through a concrete example, then do a hands-on exercise that fits in 10 minutes. Mark the day complete when you finish. At the end of Day 28, a PDF certificate with your name on it unlocks and downloads.
- Read a short framing (why this tool matters, and what it replaces).
- Watch a walkthrough: a real task, broken into 4–5 concrete steps.
- Do a 10-minute exercise on something you actually need this week.
- Mark the day complete — your progress is saved locally in your browser.

How to use this course
- Anywhere you are. All 28 days are published here, always free, always online.
- Progress is local. Your completion ticks are saved in your browser. If you switch devices, you’ll need to re-mark days on the new device — this is intentional; no account, no tracking.
- Pace yourself. 15 minutes a day is the promise. You can double up on weekends, or take a rest day — nothing expires.
- Skip around. The days mostly stand alone. Day 27 (capstone) and Day 28 (certificate) are the only ones that assume the rest.
