AI sales workspace combining a parallel dialer with conversation intelligence, call scorecards, and live coaching.
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.

Nooks is an AI-powered sales workspace built primarily for outbound prospecting, combining a parallel dialer with conversation intelligence and coaching features. Its core is an AI dialer that places multiple calls at once, detects live human pickups, skips bad numbers and voicemails, and automatically logs notes and call outcomes, increasing the number of live conversations a rep can have. Around the dialer, Nooks provides conversation intelligence: it syncs call recordings and transcripts for unified analysis, generates AI call summaries and dispositions, and produces call scorecards and battlecards to support coaching. Managers can listen to live calls and provide whisper coaching to reps in real time, and a virtual salesfloor supports team collaboration during calling sessions. The platform also includes sequencing, AI-driven research and personalization, intent signals, and lead prioritization to support the broader outbound workflow. Nooks is aimed at sales development representatives, business development teams, and revenue operations leaders at mid-market and enterprise organizations who want to scale outbound calling and conversation analysis together rather than as separate tools. Pricing varies by plan. Check the official website for current pricing.
