Hey HN,

Like many of you, I've been frustrated with the iOS keyboard for years. Autocorrect gets worse with every update. Switching between languages is painful. Dictation dumps raw unformatted text. Apple doesn't seem to care.

So instead of switching to Android, I built Cerebro. It's a custom iOS keyboard that uses AI to actually help you write.

How it works: you type (or speak) what you want to say, pick a mode, and Cerebro rewrites it. That's it. No app switching, no copy-pasting into ChatGPT.

The feature that changed everything for me: Translation + Tone combined. I'm German, and I write messages in both languages all day. Now I just talk in German, pick "Professional English," and get a polished email. Or I write quick notes and pick "Friendly" to get something natural.

Other modes: grammar cleanup, summarize, expand, and you can create your own custom prompts.

Some background: I'm actually a bread baker. I run a YouTube channel called The Bread Code (350K subscribers) teaching people how to bake sourdough. But I'm also a software engineer, and this keyboard started as a side project to solve my own problem.

Built in Swift. Currently in TestFlight beta.

Would love to hear what you think. Happy to answer questions about the keyboard extension API (it's... interesting to work with).","url":"https://testflight.apple.com/join/x98U4HCk","domain":"testflight.apple.com","comments":[],"comments_count":0}
