No Nimbus account required. Optional cloud inference. No telemetry. Models you choose are downloaded to your device and run locally. Processing stays on your phone unless you explicitly enable optional network features (such as web search or a BYOK cloud provider in Cirrus). Purchase Nimbus8 Pro once through Apple In-App Purchase. Restore anytime with your Apple ID. Family Sharing follows Apple's IAP rules. Privacy policy: https://trynimbus.org/privacy.html

About

WhoSpoke

Read full description

Editable transcripts that show who said what, stay linked to your original audio, and keep your recordings and transcripts on your iPhone. You just finished an interview, a lecture or a long family talk, and now you need to know who said that one thing. WhoSpoke records the conversation, then separates the speakers afterward. You get a transcript of speaker cards instead of one long block of text. Tap any sentence and the original audio plays from that exact moment. The sentence being played is highlighted, and the list follows along. Fix what the transcript got wrong. Rename speakers, change their colors, reassign a sentence, merge or add speakers, and edit the text. You can restore the automatic version of any sentence you've edited. What you can do: • Record in person with live captions where your language supports them • Import audio files from Files • Filter the transcript by speaker and search by title or text • Translate a finished transcript into another language on your iPhone • Export text or Markdown, with or without timestamps and translations • Share the original audio only when you choose to Transcription and speaker separation run on your iPhone. Your recordings and transcripts never leave it. Language models may download the first time you use a language. Try it free on your first three conversations. After that, a single one-time Pro purchase unlocks new recordings and imports. There is no subscription. Conversations you've already made stay fully usable either way. WhoSpoke records in-person conversations. It doesn't record phone calls or audio from other apps. Please get everyone's consent before you record. Speaker separation is good but not perfect, so you can always correct it.
