Things worth asking
What it will and will not do
The assistant is handed a slice of this site’s own database (the entries your question touches, their facts, their prices with observation dates, and the relationships between them) and is instructed to answer from that and nothing else. Where the archive holds no record, it says so instead of guessing.
It will not recommend a maker, rank houses, or tell you what to buy. Those are your decisions; the site’s job is to describe differences accurately. Prices it quotes carry the month they were observed, because a price without a date is not information.
Answers are generated with an AI model and can be wrong. Every claim it makes is on a page you can open and check, and the sources are listed there.
