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.

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.

SRTGen is an AI-powered subtitle and transcription platform centered on producing professional caption files. Users can upload video or audio, or paste links from social platforms, and SRTGen generates time-coded subtitles with automatic speaker separation. While it is marketed heavily toward creating SRT files and translated subtitles for content like YouTube and short-form video, the platform explicitly extends to corporate meetings, conferences and events, and academic and market research, including interviews and focus groups. It supports a large number of languages and locales with global dialect coverage and offers translation alongside transcription. Output options include subtitle formats such as SRT, VTT, and ASS, as well as document and data formats like DOCX, PDF, TXT, and JSON. SRGen includes a timeline-based subtitle editor with animation capabilities, the ability to burn hardcoded subtitles into video, and real-time multi-user collaboration. The service runs on a credits-based model rather than a fixed subscription, with a small free allotment to start, making it flexible for occasional caption jobs as well as recurring meeting and interview transcription needs across teams and organizations. Pricing varies by plan. Check the official website for current pricing.
