Japanese AI meeting-minutes service (formerly Smart Scribe) that transcribes and automates the full minutes workflow for businesses.
Callabo (콜라보) is an AI meeting assistant developed by Return Zero (리턴제로), a Korean speech-AI company. It automatically records, transcribes, summarizes, and analyzes business meetings for both individuals and enterprise teams, aiming to turn a one-hour meeting into organized notes with a single click and no complex setup. Callabo connects to online meetings on Google Meet, Microsoft Teams, Zoom, and Webex, and also supports recording in-person meetings. After a meeting it produces transcripts, paragraph summaries, key discussion points, and action items with timestamped source quotes, and it can automatically detect the meeting language to handle multilingual conversations. An AI chat feature lets users ask follow-up questions about a meeting beyond the generated insights. The service integrates with workflow tools including Google Calendar, Outlook, Salesforce, Pipedrive, HubSpot, Slack, Microsoft Teams, Zapier, Notion, Confluence, and Linear. For enterprises, Callabo provides meeting access controls, team and member permission management, original-media retention settings, two-factor authentication, IP access restrictions, and audit logs, and it holds ISO/IEC 27001 certification. Mobile apps are available for both iOS and Android. Pricing varies by plan. Check the official website for current pricing.

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.
