Carbon Voice
Carbon Voice is an asynchronous voice messaging app for teams and individuals, with transcripts, AI catch-up, and cross-device access. It helps people and agents communicate without needing a live call.
Overview
Carbon Voice is an asynchronous voice messaging app for teams and individuals who want to talk instead of type. It centers voice-first communication, but keeps transcripts, text input, and AI assistance in the flow so conversations stay readable and searchable.
The product is designed for people and agents in one place. Users can assign hotkeys to reach contacts quickly, share voice updates through links, and use AI to summarize, organize, and document conversations. The result is a workflow aimed at reducing scheduling overhead and making it easier to move ideas, requests, and follow-ups through a team.
Features
Broadcast updates by voice
Record short voice updates, share them as a link, and paste them into other channels when you want to replace a meeting or status call with an async update.
Automatic transcripts and search
Every voice message is transcribed automatically, making conversations readable, searchable, and easier to scan later on premium plans.
Multimodal voice and text
Voice and text both work in the same conversation, so you can speak, type, read, or listen depending on the situation. Text messages can be played back as audio, and voice messages are transcribed.
AI catch-up and action handling
AI can summarize long messages, surface action items, help you catch up on busy threads, and answer questions about conversations or voice memos.
Cross-device access and integrations
Carbon Voice works on mobile, desktop, Apple Watch, and iOS widgets, and it connects with tools such as Zapier, Google Apps, Claude, Cursor, and webhooks.
Use Cases
Async team updates
Send a short voice update instead of scheduling a meeting when you need to explain an idea, share context, or ask for a decision without waiting for everyone to be available.
Voice memos and idea capture
Capture a thought on your phone, desktop, Apple Watch, or widget before it disappears, then keep it as a transcribed note you can revisit later.
People and agent workflows
Route conversations to internal agents or connected tools using hotkeys and webhook-style access, so people can reach the right assistant or workflow quickly.
Meeting-free catch-up
Review a busy conversation by jumping to AI summaries, action items, or catch-up prompts instead of listening to every message in full.
External sharing without app install
Share a message with someone outside the app by email or secure link, allowing them to listen, read the transcript, and respond without installing Carbon Voice.

FAQ
What makes Carbon Voice different from other communication apps?
Carbon Voice is built around asynchronous voice messaging rather than real-time calls or chat threads. It is designed so people can talk when it works for them and reply when it works for them, with automatic transcription and optional AI support for catch-up.
What is asynchronous communication?
Asynchronous communication means you do not need to respond in real time. You can send a voice message when it is convenient, and the recipient can listen, read the transcript, or reply later. Carbon Voice positions this as faster than typing and more flexible than meetings.
What platforms does Carbon Voice work on?
Yes. Carbon Voice is available on iOS, Android, and the web, and it also has an Apple Watch app for capturing voice memos on the go.
Can people without the app still receive and reply to messages?
Yes. You can send a message to someone by email even if they do not have the app. They receive a secure link in a browser where they can listen, read the transcript, and reply by voice or text.
Can Carbon Voice transcribe, search, and translate messages?
Yes. The FAQ states that voice messages are automatically transcribed, searchable on premium plans, and can be translated with Global Voice into the recipient’s preferred language.
