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 Carbon Voice when capturing spoken ideas and turning them into structured documents, emails, or action items matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.
