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 Convo when capturing and summarizing slack huddles and voice calls that lack native recording matters most. Run both through a week of actual calls to see which suits your workflow.

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.

Convo (itsconvo.com) is a native desktop AI meeting assistant for macOS and Windows that captures audio locally from your device rather than joining calls as a bot. It works across Zoom, Google Meet, Microsoft Teams, Webex, and Slack Huddles, so it is not locked to a single conferencing platform. During a call, Convo listens in real time and surfaces on-screen suggestions such as talking points and objection handling that only the user can see, positioning it toward sales and customer-facing conversations. After the call, it produces structured summaries, extracts action items, and can draft follow-up emails. A notable part of its design is the integration layer: Convo turns conversations into structured data that can be pushed to CRM, documentation, and project tools, with marketplace-style connectors for Slack, Notion, HubSpot, Salesforce, and others, plus automation via Zapier, Make, IFTTT, and Power Automate and a public API. Audio is processed locally for privacy, with optional cloud processing only when a user chooses to save a recording. Pre-meeting preparation pulls context from past conversations. The product is actively operating and listed across software directories in 2025/2026. Pricing varies by plan. Check the official website for current pricing.
