How Hosiqo compares and tests toolsFinal recommendation
Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and TwinMind when users who prefer a bot-free, privacy-conscious notetaker over tools that join the meeting matters most. Try them side by side on real calls before deciding — needs vary by team.
Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
Browser-extension and mobile AI meeting assistant that transcribes calls in real time on-device and turns them into searchable 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.

TwinMind is an AI meeting assistant delivered as a Chrome browser extension and companion mobile app that captures, transcribes, and summarizes conversations from video calls and in-person meetings. The Chrome extension works alongside Google Meet, Zoom, and Microsoft Teams to produce real-time transcripts and then generate structured notes and action items after the call. Rather than sending a separate bot participant into the meeting, TwinMind transcribes the audio playing on the user's device, so there is no visible 'recording bot' announcement. The company emphasizes a privacy-first design: the product states that audio is not stored and that only text transcripts are kept, with data saved locally and optional encrypted cloud backup. TwinMind supports a large set of languages and lets users query their past conversations through an AI chat interface, positioning itself as a personal 'second brain' for recall. It markets a single experience spanning desktop browser and phone so meetings, voice notes, and ambient conversations can be captured in one place. The product is actively maintained and operating in 2025-2026. Pricing varies by plan. Check the official website for current pricing.
