Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Userology when scaling generative ux interviews without researcher bottlenecks 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.
Vision-aware AI UX research agent that moderates usability and concept-testing interviews and reports task metrics and insights.
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.

Userology is an AI UX research platform built around a vision-aware AI moderator that conducts user research interviews and usability tests at scale. Unlike text-only interview bots, its moderator can watch participants complete tasks on screen, layering in interaction analysis to evaluate how users actually navigate a product, and it asks context-aware follow-up questions, detects silence, and handles technical glitches during a session. The platform supports several research methods, including generative voice interviews, prototype testing with Figma links, live product research on existing Android, iOS, and web experiences, and diary studies, with additional evaluative methods noted as in development. It supports moderation in 40-plus languages and offers built-in participant recruitment from a large panel, plus an integration with User Interviews for additional targeting, screening, and recruitment. After sessions, Userology automatically generates reports that combine transcripts, qualitative and quantitative patterns, and key metrics, and it lets teams chat with their research data to dig into findings. The product positions itself as a way for product and design teams to compress research timelines from weeks to days while reducing the manual hours typically required for moderating and analyzing studies. Pricing varies by plan. Check the official website for current pricing.
