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.

Live meeting transcription and AI notes without a bot in the call
Real-time transcription in Google Meet, Zoom, and Microsoft Teams without a bot joining the call, with speaker identification.
Generate meeting summaries and action items in one click, or ask AI your own questions during and after the call.
Create reusable prompts and automations that push meeting insights to Slack, Notion, Linear, HubSpot, and other tools.
Tactiq is a verified connector in Claude's directory, a plugin in ChatGPT's directory, and offers an MCP connector for your meeting history.

Industry giant for live transcription and searchable conversation archives, but requires bot entry or direct audio uploads.

Extremely popular meeting assistant with great free tiers and summaries, though it relies on a calendar bot rather than a browser extension.

Robust enterprise meeting search and CRM integration capabilities, though it uses a bot participant in calls.

SpecialistAI note taker that transcribes, summarizes and visualizes meetings
Excellent video snippet clipping and multi-platform meeting recording, though uses bot joining instead of extension capture.

Operates as a bot-free browser extension just like Tactiq, capturing high-quality local meeting transcripts without annoying calendar bots.

Excels at experiment tracking and model registry workflows, but is less purpose-built for real-time LLM production observability.

SpecialistAI notetaker and company brain that turns every meeting into searchable knowledge

Free / Open-sourceIncludes integrated guardrails and simulation tools, but is less mature for large-scale enterprise production telemetry monitoring.

Free / Open-sourceFeatures strong testing and prompt evaluation tools, though its monitoring interface is less oriented towards massive telemetry streams.

Free / Open-sourceOpen-source and privacy-first local desktop meeting assistant, offering full data control unlike cloud-dependent tools like Tactiq.


Focuses heavily on prompt management and versioning control, whereas Arize prioritizes end-to-end tracing and ML observability.
