Shortlist BB Recorder when regulated or privacy-sensitive teams that cannot send audio to the cloud matters most, and Carbon Voice when capturing spoken ideas and turning them into structured documents, emails, or action items matters most. Run both through a week of actual calls to see which suits your workflow.

Carbon Voice is an asynchronous voice-messaging app that automatically transcribes voice memos and uses AI to generate summaries, action items, and documents.
BB Recorder is a local-first meeting recorder built by the team behind BuildBetter, designed for people who want meeting capture without any data leaving their device. Rather than dropping a bot into a video call, BB Recorder captures the computer's system audio directly, links to the user's calendar, and turns rough conversation audio into clean transcripts and summaries. Its defining characteristic is that recording, transcription, summarization, and even live AI chat about the meeting can all run locally using on-device models, so there is no server holding the audio or transcripts. The company frames this as making a data breach architecturally impossible because there is no cloud store to compromise, and it points to SOC 2 and HIPAA considerations along with an AI transparency policy. BB Recorder is positioned as a genuinely free, unlimited option for Mac, with no trial tiers or required registration when using local models, and a companion iOS app extends capture to the iPhone. It is aimed at privacy-sensitive professionals, regulated teams, and anyone who wants automatic meeting notes without a visible bot or a cloud transcription pipeline. Pricing varies by plan. Check the official website for current pricing.

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.
