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 Optiverse when enriching crm records and follow-up tasks from sales meetings matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Swiss AI meeting assistant (Optiverse AG, Zurich) that transcribes meetings, generates summaries and action items, and feeds CRM and workflow tools.
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.
