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 Kai for Chrome when generating quick meeting summaries and action items without any setup matters most. Try them side by side on real calls before deciding — needs vary by team.

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.

Kai is a Chrome extension that transcribes and summarizes meetings entirely within the browser, running the full pipeline on the user's own device. Built by Morgen, the team behind the Morgen calendar app, it captures audio from any meeting or audio tab in Chrome, including Google Meet, the Zoom web client, and Microsoft Teams, without sending a bot into the call and without requiring an account or sign-up. Recording is triggered with a keyboard shortcut from the meeting tab. Audio capture happens in an offscreen document inside the extension and is transcribed locally using a Whisper speech-to-text model running via WebGPU or WebAssembly, so the audio never leaves the machine. At the end of a call, a local language model produces a clean summary with decisions, topics, and action items, including who is responsible. A side-panel interface lets users follow the transcript live during the meeting, and notes can optionally be emailed to a team in one click, at which point only the final text is shared. This makes Kai well suited to individuals who want fast, private, browser-based meeting notes without installing a desktop app or adding a visible bot, with an initial focus on English-language meetings. Pricing varies by plan. Check the official website for current pricing.
