Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
Chat with your data to get analysis, charts, reports, and slides
Ask questions in plain English and get computed answers, statistics, and interpretations instead of raw formulas.
Analyze uploaded spreadsheets without writing formulas or scripts, with results returned in readable tables.
Generate visualizations on demand and assemble them into dashboards for recurring reporting needs.
Turn analyses into formatted reports, presentation decks, and simple web pages or apps.
