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 Sotto when privacy-first transcription of imported audio recordings on-device matters most. Try them side by side on real calls before deciding — needs vary by team.

Sotto is a native macOS voice-to-text dictation app that turns speech into text system-wide using local AI transcription models.
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.
Best suited for
Sotto is a native Swift dictation app for macOS 13 and later that converts speech to text in real time. It works as a system-wide push-to-talk layer: the user holds a hotkey, speaks, and Sotto inserts clean text into whatever app is in focus, from Slack and Notion to Xcode and email fields. Audio is transcribed by local engines, including OpenAI Whisper models (Tiny through Large V3 Turbo and Distil Large V3) and NVIDIA Parakeet v2/v3, so by default recordings never leave the Mac; users can optionally connect cloud providers such as OpenAI or Groq with their own API keys for added accuracy. Beyond live dictation, it can import and re-transcribe audio files, supports 90+ languages, keeps a searchable history of recordings with timestamps, and offers a custom vocabulary dictionary. One-click AI processing can rewrite, summarize, translate, or reformat dictated text. It is aimed at developers, writers, and privacy-conscious professionals who want fast, local voice input rather than a cloud meeting-bot service.
