Life Recorder — An AI voice diary app for iPhone and Mac
A simple way to record and transcribe voice notes on iPhone, locally on Mac, without cloud or subscription.
This is a life recorder application built by the browser use group. This app records ~1 min of AAC audio on your iPhone (~iOS) device. Then it transfers these audio files to your Mac over LAN, where they are transcribed locally using Whisper’s whisper.cpp library. The resulting transcriptions are appended to a growing markdown file. Alongside the transcriptions, there are also hourly timestamp markers. After receiving the audio files and transcribing them, the mac deletes the audio files off the phone. There are no cloud services or 3rd party transcription providers involved. Communication between the mac & phone is secured via a self signed TLS certificate and a 256 bit random bearer token. To build this app for iOS, you will need xcode and a free apple developer account. For this application we have written a SKILL.md playbook, so a codex agent can inspect the code, build it, and deploy it to a connected iPhone device without much human involvement.
Why a vibe-coder should care
Using voice to record your thoughts is the quickest way to do it while on the go. You don’t have to pay any monthly fees, or worry about losing your privacy. And once the audio is transcribed, you can easily feed the resulting markdown file to any AI applications for further processing.
How to install
Copy this and send it to your agent — Claude Code, Codex, any of them:
Deploy life-recorder from https://github.com/browser-use/life-recorder — follow SKILL.md, build the iOS app with Xcode, and install it on my iPhone. Ask me for the Apple developer team ID and phone connection details if needed.
Requires an iPhone and a Mac with macOS. Whisper small model (~140 MB) downloaded separately. No GPU needed — transcription runs on CPU.
