A voice-first AI workspace for Mac that records meetings without a bot, transcribes audio, and turns conversations and dictation into structured notes.
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.

Mumble AI is a voice-first workspace built for macOS that captures meetings, voice memos, and system-wide dictation, then turns spoken audio into structured, organized notes. Rather than sending a bot into a call, Mumble records directly from the Mac's system audio, so no extra participant appears in Zoom, Google Meet, Microsoft Teams, or Slack calls. It can auto-detect when a meeting starts via Google Calendar integration, display a live transcript with speaker labels during the conversation, and produce a summary with decisions and action items once the meeting ends. Beyond meetings, Mumble offers system-wide dictation that works in any text field, auto-organizing voice notes, and customizable templates for consistent note formatting. A notable feature is its dual processing approach: a cloud mode aimed at higher accuracy across many languages, and a fully local on-device mode where recording, transcription, speaker identification, and summarization run entirely on the Mac and work offline so audio never leaves the device. It is aimed at Mac users, including privacy-conscious professionals, who want hands-free capture and quick note generation. A companion iOS app, Mumble Note, syncs voice captures to the Mac. Pricing varies by plan. Check the official website for current pricing.
