Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Gistly when collections and support teams monitoring regulatory and sla compliance matters most. Run both through a week of actual calls to see which suits your workflow.

Gistly is an AI conversation intelligence platform that transcribes and audits 100% of contact-center calls for quality assurance and compliance, with native Indic code-switching analysis.
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.

It transcribes calls in 100+ languages with speaker identification and business-vocabulary tuning, then runs automated QA scoring against custom scorecards so teams can audit every conversation instead of sampling a handful. The platform surfaces time-stamped compliance flags, quality flags, sentiment and objection analysis, and AI call summaries tied to outcomes, plus real-time agent coaching and analytics. A distinguishing feature is its handling of multilingual and Indic code-switching audio, following conversations that mix Hindi, Tamil, Telugu, and other regional languages with English mid-sentence. Gistly also offers Voice AI monitoring to test and continuously watch AI agents in production, including hallucination detection. It integrates with platforms such as NICE, Salesforce, Zoho, Freshworks, HubSpot, and Genesys, and supports API and webhook connections.
