How Hosiqo compares and tests toolsFinal recommendation
Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and MeetingBot when teams that want to self-host meeting capture on their own aws infrastructure for privacy matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

MeetingBot is an open-source meeting bot API that provides the infrastructure for sending bots into Google Meet, Microsoft Teams, and Zoom calls and recording them, so developers can build applications on top of meeting-recording data with a small amount of code. The project exposes a unified REST API for managing bots and accessing meeting data including video, audio, transcripts, and metadata, and ships with a visual dashboard for managing bots and viewing captured data. A distinguishing characteristic is that its entire infrastructure is defined using Terraform and deployed to AWS, which is intended to let teams self-host the platform on their own cloud account to keep meeting data private and control costs. The stack is primarily TypeScript, using a Next.js frontend, an Express backend, PostgreSQL, tRPC, and Drizzle ORM, and the project runs on scalable AWS ECS infrastructure. MeetingBot is positioned as an open-source alternative to closed-source meeting-bot vendors for developers who want recording and transcription capabilities without sending data through a third party. The project maintains a public landing page, an active community channel, and a GitHub repository under the LGPL-3.0 license. Pricing varies by plan. Check the official website for current pricing.
