Research transparency

Sources we use

The assistant uses search to find pages, then prefers primary sources for the actual claim. A source is a starting point, not proof: prices, laws, medical guidance, platform rules and market data change and must be checked on the provider's own page and date.

Prefer a primary source: the official site, government page, standards body, filing, documentation or dataset.

Use a reference source for orientation, then open the primary source before quoting a fact or price.

For anything that changes, record the page date and the time you checked it; never present stale data as current.

Use search engines for discovery, not as the authority. Open the result and read the page.

Prices, availability, laws, medical guidance, crypto values and platform rules must be verified on the provider's own page before acting.

If sources conflict or the primary page cannot be read, say so and show the uncertainty instead of guessing.

Respect paywalls, robots.txt, terms of service, copyright and privacy; never bypass access controls.
