Proudfrog is a Stockholm-built meeting transcription and knowledge-base tool that records discreetly via iOS and macOS apps and produces speaker-labeled transcripts in Swedish, Norwegian, Danish, and Finnish.
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.

Proudfrog, built by Proudfrog AB in Stockholm, is a meeting transcription and knowledge-base platform focused on Nordic languages. Instead of sending a bot to join a call, it records discreetly through its iOS and macOS apps, capturing in-person conversations as well as meetings on Zoom, Teams, and Google Meet. It then transcribes the audio in Swedish, Norwegian, Danish, or Finnish and identifies each speaker by name, with voice recognition that learns participants across meetings. Beyond producing a searchable transcript, Proudfrog structures the content with AI: it extracts decisions and links people and projects across conversations so each meeting adds to a growing knowledge base. Users can search that archive by meaning, ask natural-language questions, and chat with their meeting history through an "Explore" feature. The company emphasizes Nordic-language accuracy, GDPR compliance, and data stored in Sweden. It is aimed at consultants, teams, and professionals working primarily in Scandinavian and Finnish languages rather than English.
