Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and Nooks when analyzing and scoring outbound calls for coaching matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

AI sales workspace combining a parallel dialer with conversation intelligence, call scorecards, and live coaching.
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.

Nooks is an AI-powered sales workspace built primarily for outbound prospecting, combining a parallel dialer with conversation intelligence and coaching features. Its core is an AI dialer that places multiple calls at once, detects live human pickups, skips bad numbers and voicemails, and automatically logs notes and call outcomes, increasing the number of live conversations a rep can have. Around the dialer, Nooks provides conversation intelligence: it syncs call recordings and transcripts for unified analysis, generates AI call summaries and dispositions, and produces call scorecards and battlecards to support coaching. Managers can listen to live calls and provide whisper coaching to reps in real time, and a virtual salesfloor supports team collaboration during calling sessions. The platform also includes sequencing, AI-driven research and personalization, intent signals, and lead prioritization to support the broader outbound workflow. Nooks is aimed at sales development representatives, business development teams, and revenue operations leaders at mid-market and enterprise organizations who want to scale outbound calling and conversation analysis together rather than as separate tools. Pricing varies by plan. Check the official website for current pricing.
