How Hosiqo compares and tests toolsFinal recommendation
Shortlist DubTab when following zoom, google meet or teams meetings in another language with live captions and dubbing matters most, and OpenOats when privately transcribing meetings on a mac without sending audio to the cloud matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Open-source macOS meeting note-taker that transcribes calls locally and surfaces relevant talking points from your own notes in real time.
DubTab is a browser extension for Chrome and Edge that translates spoken audio in real time as it plays in a browser tab. Rather than requiring file uploads or exports, it listens to the audio of whatever tab is playing and produces live translated subtitles on screen, optional bilingual (original plus translation) captions, and low-latency AI voice dubbing that speaks the translation aloud. The vendor states audio stays in the tab and only text segments are processed, and that translations appear with roughly half-a-second latency suitable for live content. It supports 50+ languages and offers voice selection and volume-ducking controls. Because it works on any site with audio, supported contexts include YouTube, Twitch, Netflix, Udemy, Coursera and Bilibili, as well as meeting and conferencing tools such as Zoom, Google Meet and Microsoft Teams, where it can show what participants are saying in real time. It is aimed at online learners, livestream and international-content viewers, and remote meeting participants who need on-the-fly interpretation and captioning.

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.
