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 VITO when capturing and sharing business call details for agents, sales, and small-business owners 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.

VITO (비토) is a call-transcription app developed by ReturnZero Inc. (리턴제로), a Seoul-based speech-AI company. It automatically converts recorded phone calls into readable, chat-style text using ReturnZero's proprietary speech-recognition engine tuned for conversational Korean. Rather than joining live virtual meetings as a bot, VITO works from a phone's call-recording function: once a call is recorded, the audio is transcribed, with speaker identification distinguishing participants, and users can later read, keyword-search, replay specific segments, and review summaries of past conversations. It also supports bulk conversion of previously recorded calls. VITO is available on iOS and Android, with PC/web access to view transcripts, and offers cloud storage so call history is preserved across devices. The company also exposes its underlying RTZR speech-to-text technology as a separate developer API. VITO is aimed at everyday users and professionals such as real-estate agents, delivery drivers, office workers, students, and small-business owners who need to revisit, search, or share the content of their phone conversations.
