Privacy-first, bot-free AI meeting companion that captures system audio locally on Mac and Windows and turns it into transcripts, notes, and summaries.
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.

Slipbox is a privacy-first AI meeting companion built for individual professionals and teams who want to capture meetings without sending a bot into the call. Instead of joining a conference as a visible participant, Slipbox runs on your own machine and captures the device's system audio alongside your microphone, then transcribes the conversation on-device in real time. As the meeting progresses it can surface real-time insights and cues, and once the conversation ends it generates AI summaries using customizable templates, tagged notes, and searchable meeting records. Because the core transcription happens locally, audio does not need to leave the device, and the product uses a hybrid model in which optional cloud features can be turned on when needed; users can also bring their own LLM API key or point Slipbox at local models such as Ollama to keep data within their firewall. It works across common communication apps including Zoom, Microsoft Teams, Google Meet, Slack, FaceTime, WhatsApp, Signal, Telegram, Discord, and Webex, and integrates with note tools like Obsidian. Slipbox is available for macOS, Windows, and iPhone, and is suited to consultants, researchers, and privacy-conscious knowledge workers who want a personal meeting record without a meeting bot. Pricing varies by plan. Check the official website for current pricing.
