How we ran this

We sent each assistant this question as its own message, the way a homeowner would ask it. It searched the web and read business sites on its own. Each answer shows which assistant and version answered and when. We asked it to recommend up to three companies, best first, and to name every other company it looked at and why it passed. Reasons are quoted as given. Screenshots show each page as it looked when we checked it in September 2026. We ask again every month and keep every answer.

Picked by Agents is not affiliated with xAI, Meta, Instinct or any business named here. Recommended means the assistant recommended it. Nothing was booked.
