Shortlist Aviso AI when revenue teams analyzing sales calls alongside pipeline and forecast data matters most, and Buzz when generating subtitles for video content in multiple formats matters most. Try them side by side on real calls before deciding — needs vary by team.

Aviso AI is an end-to-end AI revenue platform for B2B sales and revenue operations teams that combines forecasting, pipeline inspection, deal intelligence, and conversation intelligence in one system. Within its conversation intelligence module, Aviso records and transcribes both online meetings (via Zoom, Microsoft Teams, and Google Meet) and offline or in-person conversations, then analyzes them to surface coaching opportunities, buyer sentiment, and deal signals. It applies natural language processing and acoustic analysis to detect sentiment and emotion through tone, pitch, and pace, and generates smart transcripts and visual summaries that highlight keywords, decision-maker comments, and next steps. Its MIKI generative-AI assistant lets users query past conversations in natural language instead of scrubbing through transcripts, and a deal room centralizes recordings, transcripts, and related communications. Aviso ties these conversation insights back to pipeline health and forecasting so managers can connect rep behavior on calls to revenue outcomes. It is primarily aimed at mid-market and enterprise revenue teams that want a single AI-native platform rather than multiple point tools. Pricing varies by plan.

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.
