Evaluate whether KERF clearly explains why an AI-generated business answer passed or failed. Work through five tasks at your own pace—no meeting, installation, company data, or personal API key required.
KERF does not trust an AI agent's prose. It executes the agent's SQL through a read-only safety layer and compares the returned rows with deterministic expected results.
A fixture run tests whether KERF's evaluation machinery works. It is not evidence that an external AI model is accurate. Live-model results are labeled separately.
Review three representative business questions. Open the expected evidence and decide whether it would help you audit an AI answer.
Compare the recorded performance, latency, and cost—not just the final answer.
Run a deterministic, zero-cost check across revenue, operations, and finance. This validates KERF's scoring and evidence pipeline without contacting an external model.
Generated SQL is treated as untrusted input. Compare an allowed analytical query with operations that KERF blocks.

A useful evaluation should leave evidence another person or system can inspect. Complete the guided run above, then download at least one report format.
Critical feedback is more useful than praise. Point out confusing metrics, weak evidence, unsafe assumptions, or missing actions. An alias is welcome.
