Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
AI-led qualitative research platform that runs video, voice, and text interviews and analyzes every signal for insights at speed.
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.

Conveo is an AI qualitative research platform that handles the full interview workflow, from recruiting participants to moderating conversations to analyzing results, with the goal of compressing research timelines from weeks to days. Its AI interviewer conducts real video, voice, and text conversations asynchronously, adapts the discussion guide in real time, and probes with contextual follow-up questions based on each participant's responses, supporting interviews across 50-plus languages end to end including the interviewer, transcripts, and reports. Researchers can upload a brief or business objective and have Conveo generate an interview guide, then begin fielding within roughly half an hour. Because it captures video alongside voice and text, the platform performs multi-signal analysis, reading tone, emotional cues, and behavior in addition to spoken content, and it links findings back to the source video moments so insights can be validated and shared. Automated outputs include executive summaries, thematic analysis, emotional insights, and quantitative data extraction. Conveo positions itself as an end-to-end platform for continuous research across consumer insights, UX, marketing, and product workflows. Pricing varies by plan.
