Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
Apple-native AI app that records and transcribes meetings, lectures, and voice memos, then turns them into summaries and rewritten notes.
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.

VoicePen is a voice-first AI note taker built natively for the Apple ecosystem, running across iPhone, iPad, Apple Watch, and Mac. The app records and transcribes spoken audio into text, handling everything from short memos to long lectures, meetings, podcasts, and imported recordings. Once a recording is transcribed, VoicePen uses AI to generate easy-to-read summaries, structured notes, and study materials, and it offers a large set of rewrite options to reformat transcripts into bullet points, professional formats, or more casual styles. It can pull in audio and video from sources such as files, Voice Memos, Zoom recordings, podcasts, and YouTube, and it separates and labels different speakers within a transcript. A chat feature lets users ask questions about the transcribed content to surface key takeaways and action steps. VoicePen supports many languages, includes offline recording, and syncs data through iCloud, positioning itself as a personal second-brain capture tool for individuals who think and work by talking rather than typing. Pricing varies by plan. Check the official website for current pricing.
