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.

A full painting studio plus friendly AI-graded drawing lessons for all ages
Pressure-sensitive brushes with hundreds of styles, layers and groups, layer masks, adjustment layers, selections, transform tools and re-editable text.
Tap-fill hundreds of outlined pictures, then press "Grade me!" so the app assesses coverage and line discipline and celebrates with sparkles, stars and medals.
Friendly step-by-step shape tutorials that award a star for every attempt, building real drawing skill without pressure.
Apply Cartoon, Oil paint, Neon, Glitch and other looks to an imported photo, and change them later without the original image ever being altered.
