Most AI answers from context. Rivar answers from the record — and when the record cannot support an answer, it says so. A confident guess is a liability. An honest gap can be closed.
Apply for Early AccessLegal, consulting, and investment work lives or dies on the record. If an assistant can produce a confident answer out of thin air, every answer is suspect.
That is the objection our early-access conversations keep returning to — and it is the right one.
A firm answers a regulator with invented history. The gap was honest. The defense is not.
One invented rationale seeded into firm memory poisons every retrieval built on top of it.
Partners stop using the tool. The institution votes with its time, and the memory never gets built.
A plausible guess has no source. A source-less claim is a liability in diligence and dispute.
When the corpus cannot support an answer, Rivar returns a no-result and names the gap.
Every claim carries its own confidence, capped and flagged when sourcing is thin.
Each claim links back to its source, so a reviewer can follow the path themselves.
AI may surface candidate reasoning. Only authorized people make it the governed record.
Every field carries a confidence score, and the corpus tracks where that confidence comes from. Claims resting on a single transcript are capped and flagged.
A reviewer does not have to take the corpus on trust. They can see what it is unsure about before they rely on it.
An honest gap can be closed. An invented one gets acted on.
Institutional memory is only worth what the firm can rely on. Silence over a plausible answer is not a limitation of Rivar — it is the product.
