Kai 9000

Open-source AI chat app that builds interactive screens, not just text. Kai 9000 is a free ChatGPT alternative with a soul, a heartbeat, persistent memories, and reinforced learning — an AI assistant that evolves with every conversation you have.

Unlike ordinary chatbots, Kai 9000 generates native interactive UI — buttons, forms, tables, charts, and full-screen apps — right inside the chat. Ask it to build a calculator, a quiz, a dashboard, or a to-do list, and it renders a real working interface you can tap, swipe, and interact with. This is AI beyond text.

🧠 Soul & Memory — A Chatbot That Knows You
Give Kai 9000 a personality by writing its "soul." It remembers what matters across conversations — your preferences, past learnings, and known issues — and reinforces that knowledge over time. Memories that prove useful get promoted into its permanent personality. The more you chat, the smarter it gets.

💓 Heartbeat — Your Always-On Personal Agent
Kai 9000 doesn't sleep. Its heartbeat system checks in on a schedule — reviewing pending tasks, emails, and trends — even when you're not chatting. Set the interval, active hours, and model. When something needs your attention, Kai 9000 surfaces it. When everything's fine, it stays quiet.

Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Kai 9000 require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Kai 9000 safe to install?

How do I update Kai 9000?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).
