About this app

Welcome to the core of artificial intelligence!

Cortex is an advanced AI platform that brings together hundreds of the world’s most powerful models into a single hub. It works even without an internet connection so you're never left stranded, collects zero chat data, and is completely customizable.

Think that's all?

• Dynamic Chat: Stop wasting time choosing an AI. Cortex automatically selects the best model for every single prompt, perfecting the responses you get.

• Advanced Tools: Weather, code execution, calendar, crypto data, global stock markets, and much more. Cortex's AIs are fully equipped!

• Voice Chat: Stop typing. Talk to your AIs as fluently and naturally as you would with a human, using real-time voice chat—even in offline mode.

• Flow Mode: Watch different AI models debate among themselves and solve complex problems autonomously. Or, jump into the discussion yourself and let the chaos begin!

• Personal Assistants: Bored of standard AIs? Have deep conversations with specialized characters like a teacher, doctor, lawyer, or even an anime girl. Don't worry—if you get bored of them too, creating your very own AI is just a few clicks away.

• Limitless Customization: Shape the interface to match your style and mood with modern, aesthetic themes.

• Transparency: Beyond keeping your data private, Cortex is a fully open-source platform. Anyone can inspect our code, or even build their own Cortex.

It's STILL not over, but if we tried to explain everything, we’d run out of characters. To experience the rest yourself, download Cortex right now and join the core of AI!

Ratings and reviews

The interface is nice and all , but I can't seem to figure out how to us the ai offline , I put my phone on flight mode and tried to search something but it didn't work the submit button just stayed grey , try to an emphasis on the supposed offline feature

This app is good! No ads and the offline AIs work well! However, the offline AIs are not that smart, and the AIs talk about some "multimodal content" in their responses/messages, and the filter is really strict.

I subscribed for ultra yet it keeps telling me I've reached my limit whenever I try to use it. This is so disgusting. I just wasted $7 of my hard earned money.
