Clear answers, with the reasoning visible.

WhatTech is not a generic chatbot. Critical technical conclusions come from structured product data and deterministic rules.

Verified data first

Every product records its source, update date, and confidence. Missing evidence produces an unknown result—not a guess.

Connectors, protocols, power limits, display capabilities, and restrictions are evaluated before any explanation is written.

Diagnosis flows avoid dangerous repair instructions and escalate batteries, mains power, high voltage, and fire risks.

Age, support, condition, repair cost, replacement cost, value, and user needs lead to an explainable recommendation.
