Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Cogram when consultants generating template-based records of client meetings matters most. Run both through a week of actual calls to see which suits your workflow.
Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
AI platform for the architecture, engineering and construction industry that automates meeting minutes and action items with strong privacy controls.
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.

Cogram is an AI platform built for the architecture, engineering and construction (AEC) industry, with automated meeting minutes as one of its core capabilities. Its notetaker captures both virtual and in-person meetings and generates minutes, decisions and action items using the firm's own templates, so output matches the documentation formats AEC teams already use. For virtual meetings it works with Zoom and Google Meet, and it integrates with Microsoft Teams, Outlook and calendars, as well as industry tools such as Procore and Autodesk, so meeting outputs can flow into project workflows. Beyond minutes, Cogram offers an assistant, email management, and support for RFIs, submittals and field reports, positioning meeting documentation as part of a wider project-administration suite. Privacy and security are emphasized: the company states it does not train AI models on customer data, holds SOC 2 Type II certification, supports SSO, MFA and role-based access controls, uses strong encryption in transit and at rest, and offers private-cloud or on-premises deployment options. Cogram is aimed at architects, engineers, consultants and contractors who need accurate, template-driven meeting records within a security-conscious, industry-specific platform. Pricing varies by plan. Check the official website for current pricing.
