The problem
You have observability.You don't have reliability.
Your traces show what your agent did. They don't tell you when it did something wrong. That gap is where failures compound, silently, across every similar request.
Your traces show what happened. Not what's broken.
Langfuse shows you 10,000 traces. Which ones have problems? Your team stares at logs for hours hoping patterns emerge.
Real failures hide in the volume because observability tools show everything — not what matters.
Your evals pass. Your agent still fails.
You wrote evals for the failures you anticipated. The ones you didn't anticipate ship to production.
A wrong tool call, a subtle context loss, a confident wrong answer — these don't trigger alerts because nobody wrote a rule for them.
Your customers are your monitoring system.
The gap between "something broke" and "you noticed" is measured in support tickets and lost trust.
By the time a user complains, the failure has been compounding across every similar request for days.
Moyai sits on top of your existing observability and adds what's missing: reliability.
The solution
Find what's broken. Know why. Fix it first.
Moyai reads your existing agent logs, surfaces behavioral anomalies, judges whether they're real failures, and routes problems to your team — fully automatic, no rules to define.
Cluster
Surface anomalies your evals will never catch.
Structural and semantic clustering groups your traces by behavior — then finds the outliers. No rules to write. No failure definitions upfront. Moyai finds what's different and surfaces what actually deviates from your agent's normal behavior.
Evaluate
Not every anomaly is a failure. We figure out which ones are.
Agentic judges — not a single LLM-as-judge call — reason step by step about whether an outlier is a real problem or just a behavioral shift. Fully automatic: Moyai evaluates whether there were agentic failures in generating the result — no configuration, no rules to define.
Alert
Know what broke, why it broke, and who should fix it.
Every alert comes with reasoning — not just "something changed" but what failed, which traces are affected, and the likely root cause. Routes to the right person in Slack. Your team gets activated, not just notified.
Integrate
Keep your stack. Add reliability.
Connect to Langfuse, LangSmith, or any OpenTelemetry-compatible tool. No new SDK. Minimal code changes. Moyai reads the logs you already generate — you get reliability in minutes, not weeks.
Compatibility
Connect your existing stack in under 5 minutes
No SDK to install. Moyai reads the traces you already generate.
Observability tells you what happened. Reliability tells you what's broken.
