How Hosiqo compares and tests toolsFinal recommendation
Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Calendly Notetaker when professionals needing summaries and action items emailed after each call matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

An AI meeting notetaker built into the Calendly scheduling platform that records meetings and generates summaries, transcripts, and action items.
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.

Calendly Notetaker is an AI meeting assistant integrated into Calendly, the scheduling platform, that extends the product beyond booking into post-meeting documentation. It automatically records and transcribes meetings and then produces recaps that include an AI-generated summary, a full transcript, and extracted action items. Recaps can be shared by email or link, downloaded as a text file, and optionally protected with a password, and they are private by default with user-controlled sharing. Users can edit a summary before sharing it, query the transcript to retrieve specific details, and receive pre-drafted follow-up emails based on the conversation. Notetaker works with Zoom, Google Meet, and Microsoft Teams, and it can capture meetings even when the user is not the host or did not schedule the meeting through Calendly itself, which lets it cover a broad range of calls. The feature does not generate recaps for meetings shorter than a few minutes or for sessions without audio. As of the latest information, Calendly Notetaker is being rolled out gradually to eligible users, with access offered through a waitlist as availability expands. Pricing varies by plan. Check the official website for current pricing.
