Conversation intelligence for sales calls inside ZoomInfo
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.

Chorus is a conversation-intelligence platform, now part of ZoomInfo, that records, transcribes, and analyzes sales calls and meetings to help revenue teams coach reps and understand deals. It captures conversations across major conferencing platforms, generates summaries and action items, and applies analytics to surface topics, competitor mentions, next steps, and risk signals across the pipeline. Rather than focusing on individual notes, Chorus aggregates conversation data at the team and deal level, giving managers visibility into what is working and where deals may stall, and it supports coaching through call libraries and highlights. As part of ZoomInfo, it can connect conversation insights with broader go-to-market data, and it integrates with CRMs so information flows into existing workflows. Chorus is aimed at mid-market and enterprise sales organizations that want deep, data-driven conversation intelligence tied to their revenue stack rather than a lightweight meeting notetaker. Platforms: Zoom / Google Meet / Microsoft Teams. Integrations: Zoom, Google Meet, Microsoft Teams, Salesforce. Pricing varies by plan. Check the official website for current pricing.
