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 Granola when keeping a searchable record of recurring team meetings matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

Granola is a desktop AI notepad for people in frequent meetings. Instead of sending a bot into the call, it captures your computer's audio directly, transcribes the conversation, and combines it with your own typed notes to produce structured summaries, action items, and follow-ups. It syncs with your calendar to detect meetings and works with Zoom, Google Meet, Microsoft Teams, other video tools, and in-person meetings via the iPhone app. A built-in AI chat answers questions across your meeting notes (for example, what you committed to during the week). Granola runs on macOS and Windows. The free Basic plan offers unlimited note-taking, custom templates, shared folders, multi-language support, and AI chat, but limits viewing notes older than 30 days. Paid tiers add unlimited history, advanced AI models, an MCP connector, API access, and integrations with Notion, Slack, HubSpot, Attio, Affinity, and Zapier.
