Shortlist CallMiner when contact centers monitoring agent performance and automating quality scoring and coaching matters most, and Vexa when streaming live, speaker-labeled transcripts into applications matters most. Try them side by side on real calls before deciding — needs vary by team.

API-first, open-source meeting transcription platform that deploys bots to capture real-time, speaker-labeled transcripts for developers.
CallMiner is an enterprise speech and conversation analytics platform, built around its Eureka product, that captures and analyzes customer interactions across voice and digital channels. It records and transcribes calls into text, then applies acoustic and linguistic AI to surface sentiment, emotion, intent, and behavioral signals — quantifying frustration, effort, satisfaction, and confidence rather than sampling a fraction of conversations. Designed for contact centers and large enterprises, it spans modules for analysis, automated agent scoring and coaching, real-time guidance during live calls, automated redaction of sensitive data, multilingual translation, and interactive dashboards. CallMiner ingests voice, chat, email, surveys, social media, and screen recordings, applying scoring models to isolate compliance risks, fraud, quality issues, and sales outcomes. It also includes generative and agentic AI features such as automatic category creation, contact summarization, and natural-language discovery. The platform is used across healthcare, finance, retail, insurance, and BPO sectors, and was named a leader in The Forrester Wave: Conversation Intelligence Solutions for Contact Centers, Q2 2025.

Vexa is an API-first, open-source meeting transcription and intelligence platform aimed primarily at developers and technical teams who want to build meeting features into their own products. Rather than being a polished end-user notetaking app, Vexa provides a developer toolkit: it deploys bots that join meetings via a URL, capture audio, and stream back real-time, speaker-diarized transcripts with low latency over WebSocket, alongside REST interfaces for programmatic bot control. Captured data can be stored and queried for retrieval and export, enabling teams to build live transcription, searchable meeting repositories, or downstream analysis on top of the platform. Vexa currently supports Google Meet and Microsoft Teams, with Zoom support indicated as planned, and its codebase is available on GitHub under an Apache 2.0 license, with both self-hosted and managed cloud deployment options. Because it exposes meeting capture and transcription as programmable infrastructure, Vexa is suited to engineering teams in areas like sales, recruiting, and other domains that need to embed meeting intelligence into custom workflows rather than rely on a standalone consumer app. It is best for developers who want control over how transcripts are captured, stored, and used. Pricing varies by plan. Check the official website for current pricing.
