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 Sona Insight when capturing lectures and interviews with custom summary formats matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Apple-ecosystem AI app that records, transcribes, summarizes, and lets you chat with meetings, lectures, and interviews.
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.

Sona Insight (also presented simply as Sona, at sona.wtf) is an AI-powered voice-to-text and meeting assistant built for the Apple ecosystem, with support across iPhone, iPad, Mac, Apple Watch, and additional Apple platforms, plus a web browser experience. The app records conversations and transcribes them into text across a wide range of languages, then automatically summarizes key points and action items. Users can apply custom summary templates tailored to meetings, lectures, or interviews, and an AI chat feature lets them ask follow-up questions, brainstorm, or draft follow-ups based on the captured conversation. Sona supports offline recording, with internet required only for processing and AI queries, and it includes Apple-native touches such as Live Activities, Dynamic Island support, and an Apple Watch app for quick capture. Transcripts and summaries are stored in each user's personal account and can be exported and shared as PDF or text. The product targets people who want to stay present in a meeting or lecture while letting AI handle transcription, summarization, and recall afterward. Pricing varies by plan.
