How Hosiqo compares and tests toolsFinal recommendation
Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and iMemo when transcribing lectures and interviews for later review matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.
Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
Cross-platform AI recorder that turns meetings, lectures, and imported files into searchable transcripts and summaries.
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.

iMemo is an AI-powered audio note-taking app available on both iOS and Android that records, transcribes, and summarizes meetings, lectures, interviews, and personal notes. Users can capture high-quality audio directly in the app or import existing audio and video files in formats such as MP3, WAV, FLAC, and MP4, then have the content transcribed into searchable text across many languages. iMemo generates AI summaries from lengthy recordings, offers dual-language viewing for translation, and can identify issues and attributions within a conversation to help surface action items. Recordings and notes are organized into projects and folders with advanced search, and content can be exported in multiple formats including TXT, PDF, and several audio formats. iMemo records without joining calls as a bot participant, capturing audio on the device instead, and it emphasizes a privacy-focused approach where data stays on the device. The app is positioned for people who want to focus on a meeting or lecture without manually taking notes and review organized, searchable summaries afterward. Pricing varies by plan.
