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.

Meetingnotes is a free, open-source AI meeting notetaker for macOS created and maintained by developer Owen Gretzinger. It is designed for professionals who want private meeting notes without recurring subscription costs. The app captures both microphone and system audio directly on the user's Mac, so it works across any meeting platform without adding a bot to the call. It then provides a live transcript and generates AI-enhanced summaries that combine the transcript with any manual notes the user takes during the meeting. Transcription and summarization run through the user's own OpenAI API key, meaning users pay only for the API usage they consume rather than a flat subscription, and meeting data stays stored locally on the device. The source code is published on GitHub under the LGPL-3.0 license, so it can be inspected, modified, and contributed to. The project lists integrations such as Slack and Notion, with additional features in development. Meetingnotes is best for engineers and individuals who want a lightweight, transparent, bring-your-own-key meeting notetaker that keeps their data on their own machine. Pricing varies by plan. Check the official website for current pricing.
