How Hosiqo compares and tests toolsFinal recommendation
Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and HiDock when capturing phone calls and bluetooth-earphone conversations for notes matters most. Run both through a week of actual calls to see which suits your workflow.

AI note-taking hardware (docks, recorders, mini devices) paired with the HiNotes app to transcribe and summarize meetings.
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.

HiDock is a hardware-and-software brand built around capturing meeting audio and turning it into transcripts and summaries through its companion HiNotes service. The product line includes USB-C docking stations such as the H1E and the O1 meeting-room dock, the HiDock P1 voice recorder for Bluetooth earphones, and the P1 mini for capturing phone calls and in-person conversations. The devices capture two-way audio from video calls, phone calls, and face-to-face meetings, including a proprietary BlueCatch technology that records through standard Bluetooth earbuds. Captured audio is sent to HiNotes, which auto-transcribes it and generates AI summaries using tailored templates organized by profession, such as sales, engineering, HR, and education. HiDock markets unlimited AI transcription across many languages, and because recording happens on the device or dock rather than through a meeting bot, no extra participant needs to join the call. The approach suits people who hold in-person or mixed meetings and want a dedicated capture device rather than a browser bot. HiNotes is available as a mobile and web app that turns recordings into searchable, actionable notes. Pricing varies by plan. Check the official website for current pricing.
