High-accuracy transcription with 42+ language translation
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.
Best suited for
Notta records and transcribes meetings and uploaded audio/video in 58 languages, then generates AI summaries, chapters, and action items. It joins Zoom, Google Meet, Microsoft Teams, and Webex calls and integrates with Salesforce, HubSpot, Notion, Slack, and Zapier. The permanent free plan is limited — 120 transcription minutes per month with a hard 3-minute cap per recording, and no transcript export — so it suits trying the product more than recording full meetings; paid plans lift the caps substantially.
