A 30-DAY AI RENEWAL DECISION

Estimate for free. Buy the record only if you need it.

There is one flagship product: a 30-day log for deciding whether a paid AI plan earned another month. note and Patreon are two ways to buy the same decision method—not two products you need to collect.

WHO IT IS FOR

Who this shelf is for

What you have after 30 days

A work-by-work record of use, time saved, and correction time, plus one written rule for the next renewal.
