Free · The Idea Filter

You have too many ideas. Which one do you actually build?

Every one of them sounds good at 2am. Six months of building is a terrible way to find out which was wrong. This free tool runs any idea through four honest gates and forces one verdict — Keep, Bench, or Scrap — so you kill the bad ones in an hour, not a quarter. Files, not software. Runs in Claude.

The filter itself

Four gates that test the idea, two checks that test you. The fixed order makes you answer the questions that kill bad ideas cheapest — before you spend a month finding out.

The copy-paste prompt

Drop in one idea and what you already run. Claude runs the scan and the gates and gives you a blunt verdict — Keep, Bench, or Scrap — with the one finding you were stepping around.

Your idea board

A running log of every verdict. Over time it shows what you kill, what you keep, and where the filter was wrong — so you stop re-litigating the same three ideas at 2am.

It's the same filter used to pick and kill real ideas: three got benched before a line of code, and the one that cleared becameKōkua, a Shopify accessibility scanner now live on the Shopify App Store underKahakai LLC. The engine said build that one.
