Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Vanie when transcribing and analyzing hinglish and regional-language customer conversations for indian enterprises matters most.

Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
Vanie is an India-first AI conversation intelligence and QA platform that transcribes and analyzes 100% of contact center calls, chats, and emails in real time.
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.

Vanie is an agentic AI conversation intelligence and quality assurance platform built for contact centers, with a particular focus on the Indian and broader APAC market. It automatically converts 100% of customer interactions across calls, chats, and emails into text, then analyzes them for sentiment, intent, objections, compliance risks, script adherence, and missed upsell or cross-sell opportunities. The platform produces call summaries, automates QA audits across every interaction rather than a sampled subset, and delivers real-time agent assistance with prompts and alerts during live calls, plus post-call coaching and performance dashboards. Its distinguishing feature is the proprietary Vanie LLM, a model the company describes as built on LLaMA and customized for contact center conversations, designed to handle Hinglish, code-mixed speech, and regional Indian dialects such as Hindi, Tamil, Telugu, Kannada, and Marathi. Vanie targets business leaders, QA teams, supervisors, and agents in high-volume, regulated sectors including BFSI, FinTech, HealthTech, and BPOs, where automated, language-aware monitoring and compliance matter.
