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 Recolx when capturing lectures or interviews and turning them into structured transcripts and briefs matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

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.

Recolx is an AI voice-recording and note-taking system that pairs portable hardware devices (the Recolx Tap, Tap Pro, and AI earbuds) with a companion mobile and web app. You capture a conversation with one tap, and the platform transcribes the audio with speaker identification, then automatically produces organized notes, summaries, and "AI Briefs" surfacing key points, decisions, and action items. Transcription covers a wide range of languages, and the app adds live speech-to-text while recording plus translation features. The hardware uses a multi-microphone array with 360-degree AI noise reduction for clearer capture in noisy settings, with long continuous recording on a charge. A library of professional templates formats notes for meetings, lectures, interviews, sales calls, and legal use, and finished content can be exported to PDF, Word, or Markdown or shared to Notion, Google Docs, and Slack. It targets professionals such as attorneys, salespeople, students, and researchers who want to stay engaged in a conversation while documentation happens automatically. The app works with the hardware or with standalone recordings.
