Trust, but verify. We built the verify part.

Four ways in, one library behind all of them. Nothing on these screens is decoration: each claim opens the studies behind it.

Meet Cenna · one answer, peer-reviewed

Ask like a skeptic. Cenna answers like a reviewer.

Cenna is Thryval’s research guide. She reads the same graded library you can browse, 159,926 studies, and answers the way a careful reviewer would: study type first, caveats left in, every claim numbered.
