Proof without overload
Evidence without overload.
KESTREL keeps three facts separate: what it examined, what supports the answer, and what it independently verified.
- 01
Sources examined
Everything KESTREL actually reads remains visible.
- 02
Supporting evidence
Only relevant support is connected to a claim.
- 03
Independent verification
Corroboration is reported as a separate threshold.

Your uploaded source and workspace conversation stay in your private account on any device until you explicitly delete that workspace -- never purged by sign-out, session expiry, or a service restart. A separate, off-by-default setting on your account page can make an eligible, de-identified workspace considered for shared learning after you delete it; uncertain or confidential candidates are never eligible.
