Don't build it. Until the internet asks for it.

Bunbun goes and reads hundreds of real pages, forums, app reviews, bug reports, hunting for people who already complained about the problem you want to solve. He brings back their exact words, with links.

Then he scores it out of 130 and says build it, change it, or don't build it.

Real people. Real words. Real links. Real no. Bunbun is listening. Press the button and he starts reading.

How it works

Four steps. You do the first one.

1

You type your idea

One sentence is enough. Tell him the problem you want to solve.

Bunbun goes looking

He reads hundreds of pages across forums, reviews and bug reports.

4

He marks it out of 130

Then says it plainly. Under 65 and he tells you not to build it.

No fluff. Just the truth.

A real report from the desk, and the one nobody wants but everybody needs.

Nobody is talking about this. That is not a good sign.

DON'T BUILD IT

He could not find anyone asking for it. He shows you every page he looked at, so you can check.

Or take one he has already done

Not everyone arrives with an idea. Bunbun keeps the ones that got through, scored and sealed, on a shelf. Every one of them carries the same evidence and the same mark out of 130 as a report you would order yourself.
