How this was captured. We used the first accessible answer in each tool's ordinary mode on 26 July 2026. Google was personalised in the UK; ChatGPT was signed out; Perplexity and CompanySweeper were signed in. Claude required authentication, so we did not substitute an answer.

What this proves. The screenshots document different company sets for this question. They do not establish universal accuracy, completeness or investment merit, and the results may change.

Why the result set changes

A flat answer versus a structured shortlist.

General tools surface prominent names in one response. CompanySweeper ranks direct fits as Core and keeps related ideas visible—but separate—as Adjacent.
