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.

joinly is an open-source middleware project (by joinly-ai) that makes meetings accessible to AI agents. It runs as a Model Context Protocol (MCP) server that equips any agent with the tools to join a live video call, capture a real-time transcript, and interact by voice or chat during the meeting. Rather than being a finished notetaker app, joinly is a framework developers use to build interactive meeting agents that can listen, answer, search the web, draft documents, and post chat messages while the meeting is in progress. It works cross-platform across Google Meet, Zoom, and Microsoft Teams (and browser-based calls), and is model-agnostic, supporting OpenAI, Anthropic, and local models through Ollama. Speech-to-text and text-to-speech are modular, with Whisper or Deepgram for transcription and Kokoro, ElevenLabs, or Deepgram for synthesis. The project is MIT licensed and deployed via Docker (with a separate CUDA GPU image), giving teams full data sovereignty. The MCP server exposes join/leave controls, transcript and participant access, audio control, chat messaging, and video snapshots, making it a building block for custom, privacy-first meeting automation. Pricing varies by plan. Check the official website for current pricing.
