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 Whisperstream when transcribing imported audio recordings privately on-device 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.

Whisperstream is a downloadable Windows desktop application from Lanreal Technologies Inc. that converts speech to text using push-to-talk dictation. Transcription runs entirely locally on the user's PC via the NVIDIA Parakeet model, so audio is never uploaded to the cloud and no account is tied to the user's voice. It works across any application without add-ins or setup, inserting dictated text directly into tools such as Outlook, Gmail, Slack, VS Code, browsers, and Claude Code. Beyond live dictation, it can import and transcribe existing audio recordings, and it keeps a searchable transcript history with audio replay, encrypted on the device. Additional features include AI cleanup that tidies spoken input, a custom vocabulary for names, jargon, and acronyms, per-app custom AI prompts, support for 25 languages, global keyboard shortcuts, and full offline operation. It requires Windows 10 or 11 (64-bit) with at least 8GB RAM. It targets professionals and privacy-conscious knowledge workers who want fast, local voice input rather than typing.
