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.

Voicegain is a speech recognition company that offers both speech-to-text APIs for developers and a packaged meeting assistant called Transcribe. Its ASR engine supports batch transcription of recorded files and real-time streaming for live audio, and it can be deployed in the cloud, in a customer's virtual private cloud, or on-premises, which appeals to organizations with strict data-control or privacy requirements. On the developer side, Voicegain provides speech-to-text, speech-analytics, and telephony-bot APIs that can transcribe audio and analyze it for sentiment, named entities, topics, and intent. Its meeting product, Transcribe, is described as a private, LLM-powered meeting notetaker that captures audio from video-meeting browser tabs and uploaded recordings, integrates with Zoom, Microsoft Teams, and Google Meet, and automatically identifies topics and highlights from a conversation. A Windows desktop app supports Zoom local recordings. Because Voicegain spans both an underlying ASR platform and an end-user meeting tool, it suits teams that want either to build on its APIs or to use a ready meeting notetaker with flexible deployment and a focus on keeping data private. Pricing varies by plan. Check the official website for current pricing.
