How Hosiqo compares and tests toolsFinal recommendation
Shortlist DubTab when following zoom, google meet or teams meetings in another language with live captions and dubbing matters most, and Grava AI when capturing lectures or study sessions and generating summaries matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Brazilian AI meeting recorder app (by MeuGuru) that records, transcribes with speaker identification, summarizes meetings and answers questions about recordings.
DubTab is a browser extension for Chrome and Edge that translates spoken audio in real time as it plays in a browser tab. Rather than requiring file uploads or exports, it listens to the audio of whatever tab is playing and produces live translated subtitles on screen, optional bilingual (original plus translation) captions, and low-latency AI voice dubbing that speaks the translation aloud. The vendor states audio stays in the tab and only text segments are processed, and that translations appear with roughly half-a-second latency suitable for live content. It supports 50+ languages and offers voice selection and volume-ducking controls. Because it works on any site with audio, supported contexts include YouTube, Twitch, Netflix, Udemy, Coursera and Bilibili, as well as meeting and conferencing tools such as Zoom, Google Meet and Microsoft Teams, where it can show what participants are saying in real time. It is aimed at online learners, livestream and international-content viewers, and remote meeting participants who need on-the-fly interpretation and captioning.

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.
