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 Sotto when privacy-first transcription of imported audio recordings on-device 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.

Sotto is a native Swift dictation app for macOS 13 and later that converts speech to text in real time. It works as a system-wide push-to-talk layer: the user holds a hotkey, speaks, and Sotto inserts clean text into whatever app is in focus, from Slack and Notion to Xcode and email fields. Audio is transcribed by local engines, including OpenAI Whisper models (Tiny through Large V3 Turbo and Distil Large V3) and NVIDIA Parakeet v2/v3, so by default recordings never leave the Mac; users can optionally connect cloud providers such as OpenAI or Groq with their own API keys for added accuracy. Beyond live dictation, it can import and re-transcribe audio files, supports 90+ languages, keeps a searchable history of recordings with timestamps, and offers a custom vocabulary dictionary. One-click AI processing can rewrite, summarize, translate, or reformat dictated text. It is aimed at developers, writers, and privacy-conscious professionals who want fast, local voice input rather than a cloud meeting-bot service.
