Lately, I’ve been really fascinated by offline AI models running **locally on-device**, without sending data to any server. With all the outages we've seen recently (like Cloudflare/OAI issues), it reminded me how much we rely on internet-based AI for everything.

So I started building my own offline AI assistant.  
No cloud, no sign-in, no data leaving device. Your chats = *your data only.*

# Why offline AI is interesting to me:

* works even without internet
* private — nothing leaves your phone
* no server costs & no monthly subscription
* runs instantly when optimized well

# Challenges I faced as a solo dev

* model size vs speed (RAM limits on older iPhones)
* getting UI simple but not boring
* optimizing inference so it doesn’t drain battery
* handling crashes from large models
* App Store review & performance requirements

It’s still not perfect offline models are improving fast but they’re not Claude/ChatGPT level yet. Still, for everyday tasks they’re surprisingly capable.

# What my app can currently do

• AI chat fully offline  
• OCR image-to-text  
• voice input + voice responses  
• dark/light mode  
• new UI & error handling improved  
• users can view images inside chat  
• multilingual responses  
• generate small HTML/CSS websites inside app  
• added very light models for old devices  
(SmolLM 135M + Qwen 0.5B)

If anyone here is interested in **offline AI**, **LLMs on-device**, **iOS dev**, or wants to try and give feedback — here’s the app:

Would love thoughts on:

* ideas to make offline AI more useful
* ASO tips / growth advice
* features you personally would want
* performance feedback on different devices

Building alone is fun, but feedback makes it better.  
Happy to answer any question!

I built an Offline AI app for iOS/Mac no cloud, no tracking, curious what you think
