Business judgment on AI products

brier

People who ask an LLM for a forecast usually cannot verify afterwards what was actually said at the time. brier seals each prediction into a hash-chained ledger before the answer exists and grades it later with proper scoring rules, giving the user a traceable, scorable prediction record; the concrete workflow and delivery format still need verification.

Why this would be needed

Start inside the user's day · Public facts + observable behavior · 2026-09-23

Use case

People making forecasts or research need to check afterwards what an LLM actually predicted at the time, and use that to judge whether the model or the call was trustworthy.

Manually logging predictions in chat history, notes or spreadsheets and reviewing them from memory, with no sealing mechanism and no consistent scoring.

Once a prediction is made it is hard to trace; hindsight recollection flatters the forecaster and there is no common scoring standard, so real skill cannot be judged.

xOcto's call

Demand is evidenced

The trend is that model output increasingly needs a receipt and a settlement, not just generation. An entry point is forecast settings where accountability matters, such as investment research calls, consulting conclusions or internal decision logs, selling a verifiable sealed-and-scored record; today only an open-source repository exists, with no evidence of a paid path.

Reason to use it

Why users would choose it

Compared with manual logging, brier seals the prediction into a hash chain before the answer exists and scores it automatically with proper scoring rules, removing the step of recalling and self-judging afterwards and making the score third-party checkable; this is an inference about why research or consulting reviewers would choose it.
