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.
AI ambient scribe and clinical AI partner for clinicians
Listens to the consultation in real time and converts it into a structured clinical note, with an emphasis on accurate drug names and specialty terminology.
Reviews the edits a clinician makes, groups recurring corrections, and proposes word library entries, auto-edit rules, and template changes to approve.
Writes referral letters, letters back to the GP, care plans, and patient recaps straight from the finished note.
Builds the day's list, stages meds, allergies and recent results per patient, and drafts ISBAR-style shift handovers.
Offers robust clinical note drafting and front desk assistance, matching Heidi's streamlined ambient scribing workflow.
