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 Luster when identifying which reps are at risk of underperforming on upcoming deals matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

AI Predictive Enablement platform that pairs realistic sales roleplay with live-call analysis to find and close rep skill gaps.
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.

Luster is a sales enablement platform that describes its approach as Predictive Enablement, combining AI-powered roleplay practice with analysis of real sales conversations. Reps rehearse high-stakes scenarios such as discovery calls and objection handling against AI buyer personas tuned to different sales stages, personas, and deal sizes, and receive feedback designed to surface where they are likely to struggle before those weaknesses show up in live deals. The platform pairs this practice environment with a live-call analysis capability the company calls EchoIQ, which reviews actual customer calls to detect how well reps apply the skills they have been practicing and where execution gaps remain. For managers and enablement leaders, Luster provides predictive insights into skill readiness, prescriptive guidance for onboarding and hiring, certification workflows, and AI-assisted coaching so that practice can be scaled across a go-to-market team. Luster is aimed at sales reps, frontline managers, and enablement teams who want to connect roleplay performance to real revenue outcomes rather than treating training as a one-off event. Pricing varies by plan. Check the official website for current pricing.
