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.

Fast Rekap (also branded FastRekap AI) is an iOS application that records meetings, lectures, and voice memos, transcribes them into text, and instantly generates structured outputs. Beyond a standard transcript, the app produces concise AI summaries that highlight key decisions and action items, and it can automatically convert the captured content into presentation slide decks and visual mind maps, which sets it apart from notetakers that produce only text notes. A smart Q&A feature lets users chat with a transcript and receive context-aware answers based on the meeting content. Notes are saved, searchable, and shareable, with PDF export and automatic email delivery of summaries and full transcripts after each recording. The app supports a wide range of languages (the listing cites support across many languages including Spanish, French, German, Chinese, Japanese, Korean, Arabic, Russian, and Vietnamese). Fast Rekap was first released in September 2025 and is actively updated, available on the Apple App Store for iPhone. It targets professionals, students, and anyone who needs to turn spoken sessions into organized, presentable documentation quickly. Pricing varies by plan.
