How Hosiqo compares and tests toolsFinal recommendation
Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Prodigal when automating qa scorecards and compliance monitoring across 100% of agent-customer interactions matters most. Run both through a week of actual calls to see which suits your workflow.

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
Prodigal is an AI platform purpose-built for consumer finance, debt collections, and loan servicing, used by collection agencies, lenders, credit unions, and healthcare revenue-cycle teams. Its core transcription and intelligence capabilities come through two products. ProNotes runs AI transcription and summarization in the background when a call ends, generating a standardized, redacted note with an at-a-glance summary and actionable insights; it works in real time for individual calls or as overnight batch processing, supports English and Spanish, and writes notes back to CRM and system-of-record applications. ProInsight applies conversation intelligence across calls, texts, emails, and chats, analyzing every interaction (not just samples) to flag compliance exceptions, automate QA scorecards using configurable evaluation parameters, and surface business and performance insights. The platform stores audio and text records centrally for auditing and offers customizable reporting. What distinguishes Prodigal is its vertical focus: rather than a general meeting recorder, it is tuned to the regulatory and operational language of collections and loan-servicing conversations, with built-in PII redaction and compliance monitoring.
