Turn your team’s judgment
into evals that scale

Your team defines what good looks like. AI applies that standard across production. Human review keeps it aligned.

Not sure what to measure? We’ll build your first eval with you, free.

Book free evals working session

Every eval starts with a decisiononly your team can make

01

Ask a question worth answering

Skip vague questions. Ask something specific, like: would we send this to an actual customer?

02

Let your experts set the standard

Domain experts answer based on how your business works. That becomes the reference.

03

Let AI apply the standard at scale

Use an LLM to judge in one pass, or an agent to investigate the context before deciding.

04

Keep AI judgment anchored to people

Send the same question to humans and AI. Track their agreement and recalibrate.

Needs review. The customer has two prior delivery failures, so the exception should apply.

What is an eval?

An eval is a set of questions asked about an agent’s output, answered against a standard your business defines. Detections identify events; evals decide whether the behavior was acceptable.
