Sivra · Verified Answer Engine
Ask a question. Sivra investigates it across sources, tests every claim against the evidence it fetched, and delivers one clear answer you can trace. Anything it can't trace to a source doesn't make it in.
This is what an answer looks like
Inquiry · Survey depth
Does caffeine improve athletic performance?
Not a wall of links. Not a chatbot's best guess.
One answer, a confidence you can see, and the evidence to check it.
How it works
01
One question, in plain language. Sivra plans the investigation and shows you the plan before it starts.
02
It searches across the web, institutions, and peer-reviewed research — then tests every claim against the evidence it actually fetched.
03
One direct answer with a stated confidence, and three lenses beneath it: Evidence, Caution, Action.
Depth, with honest timing
1 credit · ~2 minutes
One pass. A direct answer when you need it quickly.
2 credits · ~5 minutes
Two passes. More sources, tighter verification.
3 credits · ~10 minutes
Three passes. The full picture, claim by claim.
Real verification takes minutes, not milliseconds. Sivra tells you how long — and works in the background.
Constellation
Every answer joins your Constellation — a map of what Sivra has verified for you.
Ask across all of it at once: your past inquiries become one queryable body of knowledge.
Related answers link themselves. The more you ask, the more it connects.
WATCHED · re-checked weekly
Does caffeine improve athletic performance?
New randomized trial on habitual users added to Evidence. Caution updated.
Watched answers
Watch any answer and Sivra re-checks it weekly — and tells you when the evidence moves, not just that it moved.
The rule
Anything Sivra can't trace to a source
doesn't make it in.
AI can be wrong. That's why Sivra shows its work — so you can check anything load-bearing before you rely on it.
Ask from anywhere, watch answers evolve, and carry your Constellation with you. Verification runs in the background and taps you on the shoulder when the answer is ready.
