Short answers to the things people ask about using the site.

How do I ask a question?

Type it the way you would say it. “Why is the sky blue” works as well as “Rayleigh scattering”. The site finds the closest article and rebuilds it around your question.

What do the badges mean?

• Source-backed — every factual sentence came from the article, and the source is listed under the answer.
• General answer — the assistant answered from its own knowledge because no article matched. There is nothing to cite, so nothing is claimed as cited.
• From the library — the answer is this site’s own written article, not a summary of someone else’s.

Does it store my questions?

Your chat history and saved answers live in this browser only. There is no account, no sign-in, and no server-side history. Saved notes are sent only when you turn memory on.

Which AI runs it?

By default the free Cloudflare Workers AI allocation. An operator can connect OpenRouter instead, and the chat can run entirely on your own machine through Ollama — in that mode nothing leaves the device.

Something is wrong with an answer

Every answer links to the article it came from. If the two disagree, the article is right — the site is a reader, not an authority.
