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.

Fast Rekap (also branded FastRekap AI) is an iOS application that records meetings, lectures, and voice memos, transcribes them into text, and instantly generates structured outputs. Beyond a standard transcript, the app produces concise AI summaries that highlight key decisions and action items, and it can automatically convert the captured content into presentation slide decks and visual mind maps, which sets it apart from notetakers that produce only text notes. A smart Q&A feature lets users chat with a transcript and receive context-aware answers based on the meeting content. Notes are saved, searchable, and shareable, with PDF export and automatic email delivery of summaries and full transcripts after each recording. The app supports a wide range of languages (the listing cites support across many languages including Spanish, French, German, Chinese, Japanese, Korean, Arabic, Russian, and Vietnamese). Fast Rekap was first released in September 2025 and is actively updated, available on the Apple App Store for iPhone. It targets professionals, students, and anyone who needs to turn spoken sessions into organized, presentable documentation quickly. Pricing varies by plan.
