How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and Grava AI when capturing lectures or study sessions and generating summaries matters most. Run both through a week of actual calls to see which suits your workflow.

Brazilian AI meeting recorder app (by MeuGuru) that records, transcribes with speaker identification, summarizes meetings and answers questions about recordings.
Alter is a native macOS application that records, transcribes, and analyzes meetings directly on the user's Mac without sending a bot into the call. Instead of joining a meeting as a visible participant, Alter captures audio from the system output and microphone, so it works across Zoom, Microsoft Teams, Google Meet, WhatsApp, FaceTime, Skype, Discord, and in-person conversations. Transcription runs through on-device models, with a choice of an optimized Parakeet model for major languages or Whisper for broader language coverage, and speaker identification is performed locally. Because processing happens on the device, recordings and transcripts stay on the Mac and the app can operate without an internet connection. Beyond raw transcripts, Alter generates summaries and action items, lets users chat with their meetings, and connects to tools such as Notion, Slack, Linear, Asana, and Jira. It targets solopreneurs, freelancers, consultants, and other professionals who want private, bot-free meeting capture on macOS. The product is actively developed and operating in 2025 and 2026. Pricing varies by plan. Check the official website for current pricing.

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.
