I had the exact same frustrations. Bilingual user(German/English), and the keyboard situation with multiple languages is even worse than what you describe.

Your post actually inspired me to stop complaining and try to fix it myself. I built an iOS keyboard that uses AI to handle the parts Apple refuses to get right. You speak or type roughly what you want to say, pick a tone or language, and it outputs clean text. The translation + tone combo alone saved me from switching to Android.

It's called Cerebro, currently in TestFlight if anyone wants to try it: https://cerebro-keyboard.app

Not trying to plug my thing here, genuinely just wanted to say: your countdown resonated with a lot of us. Some of us just dealt with it differently.

Show HN: Cerebro – I got tired of waiting for Apple to fix their keyboard

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.

Try it: https://testflight.apple.com/join/x98U4HCk Website: https://cerebro-keyboard.app

Would love to hear what you think. Happy to answer questions about the keyboard extension API (it's... interesting to work with).

It would be great if this were possible. I believed it could be done initially, but then I realized it depends on too many parameters: Flour, water, temperature, sourdough starter microbes, starter microbial activity level, desired consistency, baking times and a few others. One guy once tried to put together a table with different starter levels: https://www.wraithnj.com/breadpics/rise_time_table/bread_mod.... In practice it doesn't work though.

Just posting this here too, my pizza calculator could be interesting too: https://pizza-calculator.the-bread-code.io/. It's part of the repo as well.

Agreed! Bread machines don't make sense. You can make a very simple dough in 1 minute of work. I recommend 500g whole rye or wheat, 400g water, 100g sourdough starter, 20g salt. Mix all with a spatula for 1 minute until no chunks of flour are left. Put into greased loaf pan. Wait until roughly doubled in size. Bake in the oven at 200°C until core temperature is 92°C.

Your sourdough is resilient can can survive for years without being fed. When dried the spores last for thousands of years :-)

Not too much yet! I am mostly focused on trying to find the best flour/water/salt combination currently.

The current repo combines most of my experience from the past years into one single framework that you can use as basis for other recipes.

Thanks for sharing - appreciated. I have been going on with baking for multiple years now and I find it really relaxing next to my engineering job. I have already opened up a PR with my latest findings. But I am still experimenting more until I am comfortable with sharing another full year of learnings.
