Brazilian AI meeting recorder app (by MeuGuru) that records, transcribes with speaker identification, summarizes meetings and answers questions about recordings.
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.

Grava AI is a Brazilian AI meeting-recorder app developed by MG Solucoes Digitais (MeuGuru), an EdTech company in Brazil. Available on iOS and Android, it records audio and automatically converts it to text with speaker identification, then produces intelligent summaries that condense long recordings into clear, topic-organized notes. Its transcription engine is oriented to Brazilian Portuguese, and the app also supports Spanish and English. Beyond transcription and summaries, Grava AI includes an interactive chat that lets users ask questions directly about a recording, a To-Do feature that turns recordings into editable task lists, and the ability to generate professional PDF reports. Practical touches include background uploads with a notification when a summary is ready, and automatic pause and resume when an incoming phone call interrupts recording so audio is not lost. The app receives frequent updates, indicating active development and maintenance. It is designed for professionals and students who need to capture meetings, classes and important conversations and quickly transform them into searchable transcripts, summaries and action items on their phone. As a mobile-first tool from a Brazilian developer with Portuguese-language focus, it fits the Latin American market for AI meeting capture. Pricing varies by plan.
