Shortlist CFAI when capturing private meeting notes and summaries without a recording bot joining the call matters most, and Mumble AI when recording and transcribing meetings offline on a mac for privacy matters most. Run both through a week of actual calls to see which suits your workflow.

A voice-first AI workspace for Mac that records meetings without a bot, transcribes audio, and turns conversations and dictation into structured notes.
CFAI (Cognitive Flow AI) is a Windows desktop application that acts as a privacy-focused AI meeting and call note taker. Instead of sending a bot into the call, it captures both microphone and system audio at the operating-system level, so no "recording started" notification appears and the tool works across Zoom, Teams, Google Meet, Discord, and any other call. Transcription runs locally on the device using Faster Whisper, with support for many languages, and CFAI states that the audio never leaves the user's computer. From the live transcript it produces speaker-labeled notes, AI summaries, and action items, and it can build a real-time "Cognitive Map" that visualizes the conversation's topics. Summaries can be generated by Claude in the cloud, or users can keep everything offline by connecting a local LLM through Ollama, LM Studio, or Jan.ai. It is aimed at professionals, educators, recruiters, and others who want meeting notes without bots or cloud audio uploads. CFAI is distributed via the Microsoft Store with a free trial and credit-based subscription tiers.

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.
