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 20-prompt guide and weekly notes are free. If we add paid products later, we’ll always say so clearly.
How will you use my information?
We only collect the email you enter, store it in Trà Đá AI’s private Google Sheet and use Resend to deliver the requested guide. We do not ask for a phone number or use a third-party email verification service.
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.
