How Hosiqo compares and tests toolsFinal recommendation
Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Observe.AI when contact-center agents getting real-time prompts and after-call summaries during live interactions 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.
Observe.AI is a contact-center conversation intelligence platform that records, transcribes, and auto-scores customer calls and chats against quality scorecards while guiding agents 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.
Best suited for
Observe.AI is a conversation intelligence and CX platform built for contact centers. It captures customer interactions across voice, chat, and email, then transcribes them using a proprietary automatic speech recognition (ASR) engine that produces diarized transcripts with built-in PII redaction. On top of those transcripts, it layers large language models to automatically evaluate 100% of conversations against configurable QA scorecards, replacing the manual sampling most quality teams rely on. The platform surfaces sentiment, keyword spotting, and operational insights, and feeds them into coaching workflows for supervisors. For frontline agents, an Agent Copilot delivers real-time guidance, next-best-action prompts, and automated after-call summaries during live interactions. It's aimed at enterprise CX, support, and sales operations in regulated industries such as banking, insurance, healthcare, and travel, and offers hundreds of pre-built integrations with common contact-center and CRM systems. Distinct points include full-coverage auto QA, real-time agent assist tied to live sentiment, and an ASR engine tuned specifically for contact-center audio rather than general meetings.
