Cloud AI is amazing. But every question you ask goes somewhere.

ChatGPT, Claude, Gemini, Grok — these are incredible tools that push the boundaries of what AI can do. But cloud AI comes with a privacy tradeoff worth understanding:

Conversations may be used for model training
Usage patterns are stored on external servers
Server-stored data can be subpoenaed or breached
Privacy terms can change at any time

For those moments when privacy matters most, Solair keeps everything on your device.

Your conversations
stay yours.

Cloud AI services like ChatGPT, Claude, Gemini, and Grok are incredible — but they process your data in the cloud. Solair is the most feature-rich private AI app for iOS: zero data collection, fully offline, with capabilities like health intelligence that no other on-device AI app can match.

No account required

Start using AI instantly. No sign-up, no email, no phone number.

100% offline processing

Every computation happens on your iPhone or iPad's neural engine. Nothing leaves your device — ever.

Zero data collection

No tracking, no analytics, no data harvesting. Your privacy is absolute.

Duress Code

Enter a secondary passcode — silently wipes all data while appearing normal.

How it works

If someone forces you to unlock your phone, enter the duress code instead of your real one. The app opens normally — but all conversations and memories are already gone. The coercion fails. Combined with app lock, Face ID, auto-lock on app switch, and lockout protection after failed attempts.

Frequently Asked
Questions

What is Solair AI?

Solair AI is a private alternative to ChatGPT for iPhone and iPad. It runs 60+ AI models 100% offline on your device with zero data collection, no cloud processing, and no account required. It's like ChatGPT, but everything stays on your phone. It's completely free to use.

Does Solair AI work without internet?

Yes, once you've downloaded your AI models, Solair AI works 100% offline. Models are downloaded once over Wi-Fi, then all AI processing happens on your device's neural engine with no internet needed. Your conversations never leave your device.

Why is cloud AI a privacy risk?

Cloud AI services train on your conversations, build profiles of your thinking patterns, can be subpoenaed or hacked, and can change their terms or shut down overnight. Solair AI eliminates these risks by running entirely on your device.

What is the duress code feature?

The duress code is a security feature that lets you set a secondary passcode. If someone forces you to unlock the app, entering the duress code silently wipes all conversations and memories while the app appears to open normally.

How many AI models does Solair AI support?

Solair AI supports 60+ models from every major AI lab, including Qwen 3, Llama 3.2, Mistral, Gemma 3, DeepSeek R1, and Qwen VL. All models run directly on your device with direct HuggingFace access for even more.

How does Health Intelligence work with my data?

Solair reads 15+ Apple HealthKit metrics directly on your device — steps, heart rate, sleep stages (deep/core/REM), workouts, HRV, VO2 max, exercise time, standing hours, heart rate recovery, walking steadiness, blood pressure, menstrual cycle, and weight. All analysis — including recovery scores, correlation insights, and visualizations — happens entirely on your iPhone. Your health data is never sent to any server, never uploaded to the cloud, and never shared with anyone.

Is Solair AI really free?

Yes, completely free. No subscription, no ads, no in-app purchases, and no corporate agenda. Built by one independent developer who uses it every day.

Can I run bigger AI models with Solair?

Yes. While Solair runs 60+ models directly on your iPhone, you can also connect to your own LLM servers via Tailscale VPN — supporting Ollama, vLLM, LM Studio, and any OpenAI-compatible API. Run a 70B model on your home machine and use it from your phone, privately over your own network. Auto-discovery finds your servers automatically, and credentials are stored securely in iOS Keychain. Still free, no subscription required.

Can I use Solair for personal or sensitive conversations?

Yes — and this is where Solair's privacy truly matters. Because everything runs on your device with zero data collection, Solair is the only AI you can trust with your most personal conversations — anxiety, emotional support, journaling, relationship advice. Cloud AI stores and processes all of this on external servers. Solair includes built-in prompts to help you get started with these deeply personal topics, knowing nothing ever leaves your device.

Is Solair AI a private alternative to ChatGPT?

Yes — Solair AI is the most full-featured private alternative to ChatGPT available. It offers the same conversational AI experience — text chat, voice mode, document analysis, vision AI — but runs entirely on your iPhone or iPad with zero data collection. Unlike ChatGPT, your conversations are never sent to a server, never used for training, and never accessible to anyone but you.

What is the best offline alternative to ChatGPT for iPhone?

Solair AI is the best offline alternative to ChatGPT for iPhone. It supports 60+ AI models that run directly on your device's neural engine, works without internet, and collects zero data. It includes voice mode, vision AI, document analysis, health intelligence, and features like conversation forking and duress code that no cloud AI can offer. It's also completely free with no subscription.

Which AI apps don't collect your data?

Most AI apps — including ChatGPT, Claude, Gemini, and Copilot — send your conversations to cloud servers for processing. Solair AI is different: it runs 100% on your iPhone with no cloud processing, no analytics, no tracking, and no account required. It's the only AI app with a duress code for emergency data wipe. For a full comparison, see our guide to the best private AI apps.

How does Solair make money if the app is free?

It doesn't. Solair is made by one person, me, Simon. I poured months of work into it because I believes Solair should exist. And I use it every day. The app is completely free but there is optional tips if you want to support my work. Mobile AI will continue to get better from here, and the local AI future is exciting.

Your device is the most private thing you own.
Your AI should be too.
