How Hosiqo compares and tests toolsFinal recommendation
Shortlist CFAI when capturing private meeting notes and summaries without a recording bot joining the call matters most, and Zell when automating sales-manager coaching with personalized plans and ai roleplays matters most. Run both through a week of actual calls to see which suits your workflow.

CFAI (Cognitive Flow AI) is a Windows desktop application that acts as a privacy-focused AI meeting and call note taker. Instead of sending a bot into the call, it captures both microphone and system audio at the operating-system level, so no "recording started" notification appears and the tool works across Zoom, Teams, Google Meet, Discord, and any other call. Transcription runs locally on the device using Faster Whisper, with support for many languages, and CFAI states that the audio never leaves the user's computer. From the live transcript it produces speaker-labeled notes, AI summaries, and action items, and it can build a real-time "Cognitive Map" that visualizes the conversation's topics. Summaries can be generated by Claude in the cloud, or users can keep everything offline by connecting a local LLM through Ollama, LM Studio, or Jan.ai. It is aimed at professionals, educators, recruiters, and others who want meeting notes without bots or cloud audio uploads. CFAI is distributed via the Microsoft Store with a free trial and credit-based subscription tiers.

Zell is a Berlin-based AI platform that captures and analyzes real sales calls to give sales teams performance visibility and automated coaching. It works across video calls, phone calls, and in-person meetings, automatically evaluating call behaviors such as talk patterns, objection handling, and discovery depth, and producing scorecards and instant AI call summaries once conversations end. A skill-gaps dashboard helps managers see who is improving and where coaching is needed, while an AI coaching component (named Dave) generates personalized feedback, coaching plans, and roleplay simulations based on each rep's actual performance, then tracks improvement over time. Zell positions itself as a layer that turns conversation insights into action and automates much of the sales manager's manual coaching workload. As a European company founded in 2024, Zell emphasizes GDPR-compliant, on-device transcription that does not require a meeting bot or store customer data. The company has validated its model with clients across the US, Germany, Italy, and Spain and is backed by European pre-seed investors. It is a newer, privacy-focused alternative to large US conversation intelligence platforms. Pricing varies by plan. Check the official website for current pricing.
