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 Thoth when users who want offline, private meeting notes on a mac matters most. Run both through a week of actual calls to see which suits your workflow.

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.

Thoth is a native macOS application, created by Matthieu Veinhard, that records, transcribes, and summarizes meetings entirely on the user's device. It captures both microphone and system audio so it can record both sides of online meetings on platforms such as Zoom, Teams, and Google Meet, and it provides live transcription with on-device speech-to-text. An on-device engine detects and color-codes individual speakers in the transcript, and the app supports a large number of languages via Whisper-based transcription. After a meeting, Thoth extracts notes, action items, and key decisions, and lets users choose between several on-device models or supply their own cloud API key, with an on-device anonymization step that can redact sensitive information before any optional cloud processing. Output can be exported to formats including PDF, Word, Markdown, and timestamped JSON. Because the app has no server and no user database, the company emphasizes that there is nothing to breach or hand over. Thoth requires Apple Silicon and is aimed at privacy-conscious professionals, those handling confidential information, and neurodivergent users who benefit from automatic capture, and it is available on the Mac App Store with an iOS beta in progress. Pricing varies by plan. Check the official website for current pricing.
