The problem

Comparing things online is broken.

A dozen tabs, products already in a database, and nobody saying what goes wrong. The same trouble for phones, tools and cities.

The idea

Name two to six things. Get one straight answer.

Say what you are comparing, it searches the live web, then gives a plain-language verdict with the full table underneath.

compare IO flow: say what you are comparing, it searches the live web, then returns a verdict
Key design decision

Every value says where it came from.

Source badges read vendor-verified, found on web, user-submitted or unverified. If the live search did not run, badges fall back to amber instead of pretending.

Interface

Designed around the decision, not the data.

A plain-language verdict, Decision Elimination Mode, who should choose which, and follow-up questions.
