High-accuracy transcription with 42+ language translation
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.
Best suited for
Notta records and transcribes meetings and uploaded audio/video in 58 languages, then generates AI summaries, chapters, and action items. It joins Zoom, Google Meet, Microsoft Teams, and Webex calls and integrates with Salesforce, HubSpot, Notion, Slack, and Zapier. The permanent free plan is limited — 120 transcription minutes per month with a hard 3-minute cap per recording, and no transcript export — so it suits trying the product more than recording full meetings; paid plans lift the caps substantially.
