How Hosiqo compares and tests toolsFinal recommendation
Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Meeting BaaS when developers building custom ai notetakers or meeting analytics matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

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.

Meeting BaaS ("Meetings Bots as a Service") is a developer-focused API platform operated by the French company SAS Spoke. Rather than being an end-user meeting assistant, it provides the infrastructure that lets developers programmatically send recording bots into online meetings and retrieve the resulting data. Through a single unified API, SDKs, and HTTP requests, developers can start recording meetings across Zoom, Google Meet, and Microsoft Teams, then access raw audio and video, full transcripts, and speaker metadata with timestamps. Transcription can be produced via providers such as Gladia or a developer's own service, and the platform offers webhooks and MCP servers for integration, plus the ability to self-host on a developer's own infrastructure. Because it exposes the underlying capture and transcription layer, Meeting BaaS is the building block companies use to add meeting recording, transcription, and AI features to their own products without each maintaining separate bots for every conferencing platform. It is best for engineering teams and startups that want to embed meeting capture and transcription into their applications rather than buy a finished notetaker. Pricing varies by plan. Check the official website for current pricing.
