How Hosiqo compares and tests toolsFinal recommendation
Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and Némos when capturing spoken thoughts as voice memos and converting them to searchable, formatted notes matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

An Apple-focused "second brain" app that records and auto-transcribes voice memos and meeting notes entirely on-device using Apple Intelligence.
Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.

Némos is a personal knowledge management ("second brain") app for the Apple ecosystem that captures and automatically organizes many content types, including voice memos that it records and transcribes on-device. Rather than joining video calls as a bot, it captures audio directly from the iPhone or Apple Watch and converts speech to text locally using Apple Intelligence Foundation Models, so data stays on the device. Transcribed audio becomes fully searchable, and recordings can be turned into formats such as bullet points, summaries, meeting notes, emails, or journal entries. Beyond voice, Némos handles screenshots with OCR, links, PDFs, notes, photos, and more, naming and filing them automatically without manual tagging. It runs on iPhone and iPad (with Apple Watch recording, Siri commands, and Chrome, Safari, and Firefox extensions), and offers two-way sync with Apple Reminders, Calendar, Notes, Photos, Files, Maps, and iCloud. It is aimed at students, researchers, writers, and professionals who want private, low-effort capture of voice and other notes. As of mid-2026 it is in private beta.
