Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and Momentum when revops and leaders generating pipeline and forecast insights matters most. Run both through a week of actual calls to see which suits your workflow.

AI conversation intelligence and revenue platform that records and summarizes sales calls and automates CRM updates and post-call workflows.
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.

Momentum is an AI conversation intelligence and revenue orchestration platform that records, transcribes and analyzes sales and customer-success calls to turn unstructured conversations into structured, actionable data. After calls, it generates AI summaries and notes and extracts key signals, then uses agent-style automations to handle downstream work such as updating Salesforce fields, advancing pipeline stages and generating call notes so reps spend less time on manual data entry. The platform is organized around purpose-built agents, including a deal execution agent for post-call CRM updates, a customer retention agent that surfaces churn signals and sentiment from conversations, a revenue-leadership agent that produces executive briefings and pipeline insights, and a coaching agent that offers call-based coaching recommendations. Momentum integrates deeply with Salesforce, connects to Slack for real-time deal notifications and deal rooms, and can sync data into warehouses such as Snowflake for analysis. It also offers botless recording for Google Meet, capturing calls without adding a visible participant. Momentum is aimed at sales representatives, customer success managers, sales managers, RevOps teams and revenue leaders who want conversation data to flow automatically into their CRM and reporting. Pricing varies by plan. Check the official website for current pricing.
