Straight answers
You might be wondering…
I’ve never used AI. Can I follow along?
Yes. Every guide starts with a familiar work situation and includes a complete example you can adapt.
Is the guide and newsletter free?
Yes. The starter guide and weekly notes are free. If we add paid products later, we’ll always say so clearly.
Why do you need my Zalo number?
So we can deliver what you requested through the Zalo OA once messaging is verified. Until then, your opt-in is safely backed up on a sheet.
Which AI tools do you cover?
We’re not blindly loyal to one tool. Each guide picks the most accessible option for the job at hand.
