Shortlist Aircall when running outbound and inbound sales calling with ai transcription matters most, and Buzz when generating subtitles for video content in multiple formats matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.
Cloud phone and call center platform with built-in AI conversation intelligence: transcription, call summaries, sentiment, and call scoring.
Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
Aircall is a cloud-based phone and call center platform widely used by sales and support teams, with an integrated AI conversation intelligence layer that runs across calls rather than as a separate bolt-on system. Its core function is to handle business calling through features like power dialing, call recording, IVR, queueing, and routing, while Aircall AI transcribes conversations and analyzes them for insights. The conversation intelligence capabilities include AI-generated call summaries, key topic recognition, sentiment analysis, talk-to-listen ratios, transcription text search, and call scoring, which together help teams spot coaching opportunities and understand customer objections and buying signals. Aircall centralizes communications in a Workspace that brings voice, text, voicemail, and WhatsApp into a threaded view around each customer, with access to recordings and transcripts. The platform logs activity and transcripts to connected CRMs, and an analytics add-on extends dashboards with advanced filters, longer history, and KPI drill-downs. Aircall is aimed at sales and customer-facing teams that want a reliable cloud phone system with conversation intelligence included, rather than running a separate dialer and analysis tool. Pricing varies by plan. Check the official website for current pricing.

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.
