How Hosiqo compares and tests toolsFinal recommendation
Shortlist AudioPen when capturing and refining personal ideas, journal entries, or brainstorms by voice matters most, and CFAI when transcribing zoom, teams, meet, or discord conversations entirely on-device for privacy-sensitive work matters most. Try them side by side on real calls before deciding — needs vary by team.

CFAI is a Windows desktop AI note taker that transcribes meetings and calls locally on-device with Faster Whisper, so audio never leaves the user's computer.
AudioPen is a voice-to-text tool that captures spoken thoughts and turns them into polished written notes. You record your voice (or upload an audio file), and AudioPen transcribes the speech, then rewrites it into clear, structured text by fixing grammar, cutting filler words, and organizing rambling input into coherent prose. Rather than producing a verbatim transcript, it reshapes what you said into finished writing in a style you select or train over time, with preset and custom styles available. It supports multiple languages and can transcribe speech in one language while writing the output in another. A SuperSummaries feature combines several notes into a single cohesive summary, and existing notes can be reformatted for different purposes such as emails or to-do lists. Built by independent developer Louis Pereira, it runs across iOS, iPad, Apple Watch, Android, Mac, and a Chrome extension, with Zapier and webhook integrations for sending notes elsewhere. It is aimed at people who think out loud and want to convert informal speech into professional written content.

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.
