About this tool
Build room-by-room keep-or-let-go prompts using the four-box, 20/20, 90/90 or KonMari rule, with a session plan.
This builder turns a room, a decision rule and the time you have into a ready-to-paste AI prompt that walks you zone by zone through keep-or-let-go choices. You choose the framework — the four-box sort (Keep, Donate or sell, Relocate, Bin), the Minimalists' 20/20 rule, their 90/90 rule, the one-year seasonal rule, or Marie Kondo's fixed category order — and it also sizes the job into working sessions from your item count and seconds per decision. It is for anyone who stalls halfway through a wardrobe or garage because there is no rule deciding for them.

Four-box, 20/20, 90/90, one-year and KonMari category order, quoted as rules rather than vague advice.
Item count times seconds per decision, divided by your working block, so the plan fits the time you actually have.
Each room preset ships with its zones so you finish one shelf before opening the next.
Let go of any just-in-case item you could replace for less than $20 in less than 20 minutes from where you normally are. It comes from Joshua Fields Millburn and Ryan Nicodemus of The Minimalists, and it exists to defuse the fear of needing something later — most such items are cheap and quickly re-obtainable.
Multiply the number of items by the seconds you spend deciding each one. At a brisk 30 seconds per decision, a 200-item kitchen is about 100 minutes of hands-on sorting, which is four 25-minute blocks. Sentimental categories run far slower, so plan them separately and last.
Both work, but they answer different problems. Room-by-room gives you a visibly finished space fast, which sustains momentum. The KonMari method insists on category order — clothes, books, papers, komono, sentimental — because gathering every item of one kind into a single pile is the only way to see how much you own.
Keep, Donate or sell, Relocate, and Bin or recycle. The discipline is that every item lands in exactly one box and nothing is left in an undecided pile — the undecided pile is what turns a clear-out into a half-finished mess.
