How Hosiqo compares and tests toolsFinal recommendation
Shortlist Agaton when coaching sales reps in real time during calls to improve objection handling and closing 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.

Agaton is a Stockholm-based AI conversation intelligence and revenue intelligence platform built for sales and customer-facing teams. The product applies voice AI to analyze agent-customer calls, aiming to review interactions rather than only a sampled subset, and surfaces signals such as buying intent, objections, sentiment shifts, and engagement levels. From these signals it generates personalized, real-time coaching guidance for reps during conversations and quality-and-compliance insights that help managers make faster decisions. Agaton evaluates sales skills like objection handling, closing technique, rapport building, and negotiation, and integrates with existing tools in the sales stack including dialers, CRM, Teams, Slack, and email. The company positions Agaton as an autonomous AI co-worker that automates core workflows so reps can focus on relationships and closing. As a European company, Agaton emphasizes European data-privacy standards, GDPR compliance, ISO 27001 certification, and automatic redaction of personally identifiable information. It was founded in 2024 and reports a customer base that includes Nordic enterprises. It is a newer, regionally rooted alternative to large US-based conversation intelligence incumbents. 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.
