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 Ma Synthèse when documenting internal team meetings with auto-assigned tasks and reminders matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

A sovereign French SaaS by GetCaaS that transcribes meetings and automatically generates structured minutes, assigned tasks, and follow-ups, with all data hosted in France.
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.

Ma Synthèse is a French SaaS application from GetCaaS that automates meeting documentation through a three-step process: it captures and transcribes spoken exchanges, organizes the discussion by topic and by speaker, then generates a clear, structured meeting report. Each report surfaces decisions and important points and produces an action list assigned to individual participants, with the tool able to send those tasks out and remind people who forget them. Its defining angle is data sovereignty: the service runs on French infrastructure (Scaleway) using Mistral AI, keeps data in France, and is positioned as a GDPR-compliant alternative for organizations with strict confidentiality needs. It targets municipal councils, public bodies and law enforcement, as well as legal and medical professionals. Pricing is usage-based, calculated from meeting hours multiplied by the number of licenses, with one free hour per month per organization and no commitment; organizations above thirty licenses get a custom quote. Announced in June 2026, it was selected to present at VivaTech 2026.
