How it works

Five steps between a question and an answer you can check.

1 · Ask

The question goes to the Wikipedia search API in the language you chose. Nothing is sent to a model yet.

2 · Research

The best-matching article is fetched in full, with its sections, and cleaned: navigation boxes, edit links, footnote markers and tables of metadata are dropped.

3 · Filter

The article is split into a lead and numbered sections, and its sentences are scored against your question. The sentences that answer it move to the top.

4 · Explain

If you are in the chat, the selected passages are handed to the model with one instruction: answer only from these, and cite them. If no article matches, the question is answered as conversation and labelled as such.

5 · Cite

Every citation points at a real passage, and every passage points at the article it came from. A marker that points at nothing is removed before the answer is shown.

What the site will not do

• It will not invent a citation to look authoritative.
• It will not present a model’s memory as a sourced fact.
• It will not claim to replace the article it summarises.
