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.

Efficlose is an AI meeting platform that captures, transcribes, and summarizes conversations through a combination of a Chrome extension, a desktop app, and a web platform. Its Chrome extension is positioned as a way to record meetings without a bot joining the call, capturing audio locally in the browser so no extra participant is announced or shown in the meeting; users can choose to capture a single tab, a specific window, or the full screen, and start or stop recording manually rather than relying on calendar triggers. For users who prefer automated joining, the desktop app and platform can connect to a calendar and send a bot to scheduled meetings on Zoom, Microsoft Teams, and Google Meet. Recordings are transcribed automatically with speaker identification, and the platform generates summaries with key decisions, next steps, and assigned action items. It also offers meeting search across past recordings and an AI assistant for querying conversations, plus integrations with business tools such as Salesforce, HubSpot, Slack, and Notion. Efficlose is aimed at teams across sales, customer success, recruiting, engineering, and project management who want flexible recording options and structured meeting outputs synced into their existing tools. Pricing varies by plan. Check the official website for current pricing.
