How Hosiqo compares and tests toolsFinal recommendation
Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Grava AI when capturing lectures or study sessions and generating summaries matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Brazilian AI meeting recorder app (by MeuGuru) that records, transcribes with speaker identification, summarizes meetings and answers questions about recordings.
Buzz is a widely used open-source desktop application that transcribes and translates audio offline on the user's personal computer, powered by OpenAI's Whisper. It is MIT-licensed and actively maintained, with v1.4.4 released in March 2026, and it has grown a large community with roughly 19.7k GitHub stars. Buzz runs on macOS, Windows, and Linux, with installation options including Flatpak, Snap, and PyPI. It supports both importing existing audio and video files and real-time transcription from microphone input, and it can export results in formats such as TXT, SRT, and VTT for subtitling and documentation. The app includes an advanced transcript viewer with search and playback controls, a watch folder for automatically transcribing new files, and a command-line interface for automation. It offers GPU acceleration through CUDA for Nvidia cards, Apple Silicon support, and Vulkan for many other GPUs, which makes faster transcription practical even on laptops. Buzz also provides speaker identification and speech separation for noisy audio, plus a plugin system that adds capabilities like AI-generated summaries. Because all processing happens locally, recordings and transcripts remain on the user's machine rather than being uploaded to a cloud service. Pricing varies by plan.

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.
