How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying 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.
Aiko is a native transcription app for macOS, iOS, and visionOS, developed by Sindre Sorhus, that converts speech to text from meetings, lectures, and recordings entirely on-device. It uses OpenAI's Whisper model running locally, so audio never leaves the user's device, which makes it appealing for students and professionals with privacy requirements. Aiko transcribes both audio and video files in common formats such as .m4a, .wav, .mp3, .mp4, and .mov, and supports around 100 languages. Transcriptions can be exported in multiple formats, including JSON, CSV, and SRT subtitles, and the app includes a word-replacement feature to automatically correct recurring errors. It also integrates with Apple Shortcuts for automation workflows. Because Aiko prioritizes accuracy over speed, it does not perform live transcription while recording and currently does not include speaker detection, so it is best for transcribing recorded lectures, interviews, and meetings after the fact. The app is offered as a Universal Purchase with a free trial via TestFlight, making it a low-cost, privacy-first option for turning lecture and meeting recordings into searchable text. 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.
