Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and TeamsMaestro when capturing action items from recurring teams meetings matters most. Try them side by side on real calls before deciding — needs vary by team.

A Microsoft Teams-focused AI note taker whose bot joins calls to transcribe, summarize, and extract action items.
Buzz is a widely used open-source desktop application that transcribes and translates audio offline on the user's personal computer, powered by OpenAI's Whisper. It is MIT-licensed and actively maintained, with v1.4.4 released in March 2026, and it has grown a large community with roughly 19.7k GitHub stars. Buzz runs on macOS, Windows, and Linux, with installation options including Flatpak, Snap, and PyPI. It supports both importing existing audio and video files and real-time transcription from microphone input, and it can export results in formats such as TXT, SRT, and VTT for subtitling and documentation. The app includes an advanced transcript viewer with search and playback controls, a watch folder for automatically transcribing new files, and a command-line interface for automation. It offers GPU acceleration through CUDA for Nvidia cards, Apple Silicon support, and Vulkan for many other GPUs, which makes faster transcription practical even on laptops. Buzz also provides speaker identification and speech separation for noisy audio, plus a plugin system that adds capabilities like AI-generated summaries. Because all processing happens locally, recordings and transcripts remain on the user's machine rather than being uploaded to a cloud service. Pricing varies by plan. Check the official website for current pricing.

TeamsMaestro, from Maestro Labs, is an AI meeting assistant built specifically for Microsoft Teams. Its bot joins Teams calls a few minutes before they start based on your calendar, or it can be invited manually by adding teams@maestrolabs.com as a participant. During the meeting it listens to the conversation and then automatically generates structured meeting summaries with key discussion points, and it identifies action items so teams can track follow-up tasks. The tool supports more than 20 languages, detecting the spoken language and providing summaries accordingly. Meeting notes are stored within the Teams workspace and shared by email to participants, keeping the workflow close to where Teams users already work. TeamsMaestro is described as Microsoft Attested and is available across desktop, mobile, and web on Windows and macOS. Because it is purpose-built for Teams rather than spanning many platforms, it is well suited to organizations standardized on Microsoft Teams that want automated transcription, summaries, and action-item capture without manual note-taking. A free tier with a limited number of monthly meeting notes is offered alongside paid options. Pricing varies by plan. Check the official website for current pricing.
