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 Otolio when sales teams preparing for and following up on client meetings matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Japanese AI meeting-minutes service (formerly Smart Scribe) that transcribes and automates the full minutes workflow for businesses.
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.

Otolio, formerly known as Smart Scribe (スマート書記), is a Japanese AI meeting-minutes service operated by Epicbase, Inc. It is designed for corporate use and automates the entire meeting documentation process rather than only producing a transcript. Users can record in-person meetings or capture audio from web conferencing tools, after which Otolio automatically transcribes the audio and generates summarized, cleaned-up minutes. Features include speaker visualization, registration of specialized terminology for improved accuracy on industry-specific vocabulary, and filler-word removal. The platform organizes recording, transcription, minutes generation, and follow-up tasks within a single interface, and offers specialized agents oriented toward meeting minutes and toward sales preparation and follow-up. Security is positioned as a core concern for Japanese enterprises: Otolio is ISO 27001 certified, uses encryption, and states that it does not perform unauthorized machine learning on user data. A mobile app supports transcription, audio playback, and file upload. Otolio is aimed at Japanese organizations that hold frequent internal meetings, sales calls, one-on-ones, and executive sessions and want to reduce the administrative burden of writing minutes. Pricing varies by plan. Check the official website for current pricing.
