How Hosiqo compares and tests toolsFinal recommendation
Shortlist Airspeed when revenue teams wanting every call scored and connected to account history matters most, and Buzz when generating subtitles for video content in multiple formats matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Airspeed, formerly known as Glyphic, is a sales conversation intelligence and revenue-team platform that records, transcribes, and analyzes calls and connects them with email and ticket history into a persistent memory of each customer account. It integrates with meeting platforms such as Zoom and Teams to capture conversations, then surfaces key themes, generates pre-call and post-call intelligence, and provides contextual answers about accounts grounded in actual interactions. For coaching, Airspeed identifies coachable moments with specific post-call scorecards, tracks metrics like talk-to-listen ratio against team benchmarks, delivers automated coaching plans before standups, and offers a practice simulator with buyer personas to build specific skills such as pricing-objection handling and champion building. It scores live calls during conversations and tracks rep improvement over time. On the workflow side, Airspeed auto-syncs data to Salesforce, HubSpot, and Outreach, works within Gmail, Outlook, and Slack, and uses agents that detect signals like champion changes or stalled deals to draft outreach for rep approval and maintain CRM hygiene. The company is based in London and New York and rebranded from Glyphic to Airspeed in 2026; it is a live, operating product. 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.
