AI research workspace that transcribes interviews in dozens of languages and turns them into cited insights, clips, charts, and reports.
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.

User Evaluation is an AI-powered research platform that automates user and customer research workflows, from recruiting participants and conducting interviews to analyzing findings, within a single workspace. It transcribes audio and video in dozens of languages with speaker labels and custom vocabulary, and processes multimodal inputs including audio, video, text, PDF, and CSV. Its AI analysis uses an agentic chat with a set of tools that cite evidence as it generates insights, identifying pain points, delighters, and themes, automatically tagging mentions, and creating visual summaries. The platform turns research into shareable outputs such as video clips saved as MP4 files, charts including bar, pie, and flow diagrams, editable reports exportable to PDF or DOCX, and presentation decks with native PPTX export. Workflow tools include interview scheduling and recording, live note-taking during sessions, survey creation with both fixed and adaptive chat-style follow-ups, and Kanban-style collections for organizing insights. User Evaluation offers a free tier to start along with paid plans that add capabilities such as white-labeling and SSO. By combining multilingual transcription, evidence-cited AI analysis, and rich exportable outputs, it aims to compress hours of research into customer insight quickly. Pricing varies by plan.
