How Hosiqo compares and tests toolsFinal recommendation
Shortlist CallMiner when contact centers monitoring agent performance and automating quality scoring and coaching matters most, and OpenOats when privately transcribing meetings on a mac without sending audio to the cloud matters most. Run both through a week of actual calls to see which suits your workflow.

Open-source macOS meeting note-taker that transcribes calls locally and surfaces relevant talking points from your own notes in real time.
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.

OpenOats is an open-source macOS meeting note-taker, created by Yazin Akkawi (the project was previously named OpenGranola before being renamed), that sits alongside your calls and both transcribes the conversation and helps you contribute to it. It captures both sides of a meeting and transcribes audio locally on Apple Silicon so audio never leaves the device, while in real time it searches your own markdown or plain-text knowledge base to surface relevant talking points and things worth saying during the discussion. The application window is hidden from screen sharing by default, which lets it stay private during video calls, and transcripts and session logs are auto-saved locally. OpenOats supports both fully local operation through Ollama and cloud providers such as OpenRouter and Voyage AI, so users can choose between complete offline privacy and hosted models. It is written primarily in Swift, distributed under the MIT license, and actively maintained with very frequent releases. The project documents itself at openoats.com and targets users who want a privacy-respecting, self-hostable alternative to cloud meeting copilots, combining live transcription with a retrieval layer over personal notes rather than only producing an after-the-fact summary. Pricing varies by plan. Check the official website for current pricing.
