grounded & cited

Answers from your sources.
Not the internet's guesses.

The assistant answers only from the documents you give it. Every claim carries a citation you can tap to see the exact passage — and when your sources fall short, it tells you instead of inventing.

Grounded, never hallucinated

Replies are built from your material only — no made-up facts.
