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.

Maestra is an AI-powered media platform that provides transcription, subtitling, translation, and dubbing for audio and video content, both on demand and in real time. For transcription, users upload audio or video and Maestra produces speech-to-text output with features such as speaker detection, punctuation, and timestamps. The platform can auto-generate subtitles and captions, which users can edit, style, and export in multiple formats, and it can translate that text across a large set of languages. Maestra also offers live transcription for meetings, webinars, and streams, with stated integrations for platforms including Zoom and Microsoft Teams, as well as live production tools. This makes it usable both as a post-production transcription and captioning service and as a real-time captioning layer over live sessions. Maestra is aimed at media companies, content creators, marketers, and organizations that need multilingual transcripts, subtitles, and captions, and that may also want real-time captioning for live events and meetings. Pricing varies by plan. Check the official website for current pricing.
