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.
ChatGPT inside Google Sheets and Excel, with no API keys required
Use AI in any cell through a simple function — no API keys, no external chat window, no copy-paste between tabs.
Drag a single prompt down a column to process thousands of rows, with identical queries cached so you are not charged twice for the same work.
Summarise, rewrite, extract and classify long bodies of text such as surveys, articles or social posts into clean structured columns.
Generate ad copy, keyword lists, SEO content and campaign structures directly from your sheet's own data.
