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.

Interactive math, coding and AI tutoring you learn by doing
Learn math, science, CS and AI through short, visual exercises that build intuition step by step rather than passive video watching.
A visual, interactive tutor that works on a shared canvas, asks guiding questions and gives hints without simply revealing the answer.
Quizzes and reviews adapt to your level, tracking what you have mastered and resurfacing topics that still need work.
Write and run real code to learn programming logic, algorithms, data structures and debugging skills relevant to the AI era.
