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.

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.

Tana is an AI-native workspace that combines outlining, knowledge management, and a built-in meeting notetaker. Its Meeting Notetaker captures, transcribes, and summarizes meetings without requiring a bot to join the call; instead, it records computer system audio directly from the desktop app, which means it works across Zoom, Google Meet, Teams, and even in-person meetings, lectures, and interviews started on the computer. On Mac, Tana can detect when a meeting link is opened and offer to start transcribing immediately. Once captured, transcripts and summaries flow directly into the Tana workspace, where the AI can extract action items and push them to task boards, link the meeting to relevant people and projects, and surface notes where they are needed. It supports many languages with automatic detection and is available on Mac and Windows desktop apps. Tana is aimed at professionals and teams who want their meeting notes to become structured, connected knowledge rather than isolated transcripts, integrating capture with an ongoing personal or team knowledge system. Pricing varies by plan. Check the official website for current pricing.
