Question

Answer

The streamed answer will appear here.

Answers are grounded only in the context above. If the context doesn't cover the question, the model will say so.

Grounded-only answers

The system prompt forces the model to either quote from the pasted context or admit that the answer isn't there. No silent drift into training data.

Free-tier friendly

Gemini 2.5 Flash is free at Google AI Studio (no credit card). Missing the env var? The route returns a clear 503 instead of breaking the UI.

Rate-limited by design

Per-IP sliding window caps abusive loops so a drive-by visitor can't drain the shared quota for everyone else.
