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.

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.

VITO (비토) is a call-transcription app developed by ReturnZero Inc. (리턴제로), a Seoul-based speech-AI company. It automatically converts recorded phone calls into readable, chat-style text using ReturnZero's proprietary speech-recognition engine tuned for conversational Korean. Rather than joining live virtual meetings as a bot, VITO works from a phone's call-recording function: once a call is recorded, the audio is transcribed, with speaker identification distinguishing participants, and users can later read, keyword-search, replay specific segments, and review summaries of past conversations. It also supports bulk conversion of previously recorded calls. VITO is available on iOS and Android, with PC/web access to view transcripts, and offers cloud storage so call history is preserved across devices. The company also exposes its underlying RTZR speech-to-text technology as a separate developer API. VITO is aimed at everyday users and professionals such as real-estate agents, delivery drivers, office workers, students, and small-business owners who need to revisit, search, or share the content of their phone conversations.
