What I build.
Miru Private voice recorder for iPhone. Listens, transcribes on-device and automatically separates speakers by their voice characteristics. Apple's new SpeechAnalyzer (iOS 26) runs entirely offline; speaker recognition happens via an ECAPA-TDNN CoreML model. After every recording a sheet opens to confirm or manually split the clusters. The finished transcript exports as TXT, Markdown or PDF through the standard iOS share sheet — from there to Mail, Notes, ChatGPT or whatever else is installed.
