Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and Simon Says when translating subtitles for international distribution matters most. Try them side by side on real calls before deciding — needs vary by team.

AI transcription, captioning, and translation built for professional video and audio 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.

Simon Says is an AI transcription, captioning, and translation platform built for professional audio and video production workflows. Users upload audio or video and Simon Says transcribes the speech into text, with speaker identification to separate dialogue, and can generate subtitles and captions using built-in visual editing tools. The platform supports transcription and translation across roughly a hundred languages, making it useful for international distribution and localization. A defining characteristic is its focus on production environments: Simon Says integrates with industry-standard editing software such as Final Cut Pro, Adobe Premiere Pro, DaVinci Resolve, and Avid, so transcripts and captions can move directly into editing timelines. This positions it as a transcription and captioning layer for video editors, producers, post-production teams, and content creators rather than a meeting note-taker. It is aimed at professionals who need accurate, editable transcripts and subtitles that fit into established editing pipelines, as well as researchers and creators who need reliable speech-to-text and multilingual captioning. Pricing varies by plan. Check the official website for current pricing.
