LLM Failure Analyzer

Diagnose why your LLM calls fail. Paste a failed response and the LLM Failure Analyzer categorizes the failure type — hallucination, refusal, schema violation, context overflow, or reasoning breakdown — and provides targeted remediation strategies for each failure mode.

Run LLM Failure Analyzer Interactively 100% client-side execution in your browser. Zero data retention.

What Problem LLM Failure Analyzer Solves

Production AI deployments require predictable token economics, rigorous parameter verification, and deterministic schema handling. LLM Failure Analyzer isolates parameters client-side before payloads hit third-party foundation model APIs.

Primary Production Use Cases

  • Debug hallucinating production agent
  • Analyze why LLM refuses user requests

Security & Data Privacy Considerations

All computations execute locally in browser memory. No prompt payloads, test inputs, or secret credentials are ever retained or stored on central servers.
