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.

GMR Transcription, founded in 2004 and based in Tustin, California, is a human-powered transcription and translation provider serving business, legal, academic, medical, and media clients. Rather than automated speech recognition, it relies on trained US- and Canada-based transcriptionists who manually transcribe recordings and apply a second proofreading pass. For meetings, it offers dedicated conference call and business transcription: clients record their calls or meetings, upload audio or video files through a secure client portal, and receive formatted transcripts back by email. Service options include custom formatting, speaker identification, timestamps and time codes, verbatim transcription, and certification or notarization. Turnaround is configurable, from multi-week economy delivery to same-day and next-day rush service, with pricing charged per audio minute. The company also provides translation in many languages and proofreading. It is aimed at organizations and professionals who need high-accuracy, confidential, human-verified records of interviews, focus groups, conference calls, and meetings rather than instant AI notes.
