## What is Cortis?

Free AI that actually lives on your phone.

Cortis runs powerful AI models entirely on your device. No internet needed, no account, no ads, no subscription. Every conversation stays on your phone.


100% FREE TO USE

3 AI models, unlimited conversations, full Siri & Shortcuts integration, image analysis — all free. No ads. No tracking. No "free trial" that expires. The free version is the real version. Pro just adds more models and power features.


ASK SIRI, GET REAL ANSWERS

Say "Hey Siri, ask Cortis" and get a real AI response — not a web link. The AI runs entirely on your phone and answers through Siri. No app opens. Works from lock screen, CarPlay, and AirPods.

Build powerful AI automations with Shortcuts:
- Safari > Cortis Summarize > Save to Notes
- Voice Memo > Extract Action Items > Reminders
- Clipboard > Translate > Paste anywhere

17 voice commands. Full string output. Unlimited chaining.


WORKS EVERYWHERE — NOT JUST IN AN APP

- Share Extension — Select text in Safari, Mail, or Notes to summarize, translate, or ask
- Spotlight — Search past conversations from your home screen
- Quick Actions — Long-press for instant new chat
- Siri — Hands-free AI from anywhere on your phone


ANALYZE IMAGES ON-DEVICE

Point your camera or share a photo — Cortis analyzes images using multimodal AI, completely offline. Describe what's in a photo, extract text, get explanations. No image ever uploaded to any server.


AIRPLANE MODE? TRY IT.

Toggle airplane mode. Ask a question. Get an answer. No Wi-Fi, no cellular — just your phone running a real language model with Metal GPU acceleration.


YOUR WORDS NEVER LEAVE YOUR PHONE

Zero data transmitted. No account. No cloud sync. Conversations stored only on your device. Not encrypted in transit — never transmitted at all.


15+ MODELS, YOUR CHOICE

Llama, Gemma, Qwen, Mistral, Phi — running natively with Metal GPU. Plus language-optimized models for Turkish, Japanese, Korean, Arabic, Chinese, German, French, Spanish & Russian. Not translated — natively trained.


CONNECT YOUR DESKTOP (Pro)

Run Ollama or LM Studio on your computer? Connect over Wi-Fi and use 70B+ models from your phone.


$14.99 ONCE — NOT $240/YEAR

ChatGPT Plus costs $20/month. Cortis Pro is one payment, forever. Start free — upgrade only when you want more models. No pressure, no paywall popups.

LOOKING FOR MORE THAN A DEMO?
Unlike showcase apps, Cortis is built for daily use. Siri integration, 
Shortcuts chaining, Share Extension, conversation history, 15+ models. 
Not a tech demo — a real tool you'll use every day.
