Histeeria is the reliability layer for production AI agents. Teams use it to monitor agent decisions in real time, evaluate judgment across eight dimensions, get alerts when quality drops, and improve agents before failures reach users. Histeeria Inc. operates under the name Histeeria — Institute of Machine Judgment. The product connects to your agents through Python and TypeScript SDKs or a REST API, with a web application at app.histeeria.com.

​
What problem does Histeeria solve?

Production AI agents fail in ways traditional logging misses:
  • They hallucinate with confidence
  • They miss escalation when they should defer to humans
  • They drift after prompt or model changes
  • They break policy under adversarial input
Generic LLM observability shows what happened. Histeeria evaluates whether the decision was good — judgment, not just tokens.

​
Who is Histeeria for?

  • Developers shipping LLM features to production
  • AI startups that need trust and auditability
  • Enterprise teams operating agents at scale
  • Dev studios building agents for clients
If you run AI agents where mistakes have real cost — support, finance, healthcare, legal, ops — Histeeria is built for you.

How is Histeeria different from generic observability?

Generic LLM tracingHisteeria
Logs prompts and completionsEvaluates decision quality
Pass/fail or human reviewEight-dimension judgment scores
Developer debugging focusProduction reliability focus
Often high overheadZero-latency async SDK
Histeeria complements tools like LangSmith or Langfuse by adding a judgment layer — scoring whether the agent decided well, not just whether it ran.
