Grounded answers with sources
A sourced answer to a question — with citations and an honest confidence, or an abstention.
What it does
Ask a question and get back an answer grounded in live sources, a calibrated 0–1 confidence, and the sources themselves — or an honest “uncertain” instead of a confident guess.
