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.

⚡ 24 Services — One App, Every Model
Connect to ChatGPT, Gemini, Claude, DeepSeek, Llama, Mistral, Grok, and 17 more providers. Run local models via Ollama or LM Studio for private, offline use. Add multiple accounts, reorder priorities, and let the smart fallback chain handle outages automatically. A built-in free tier means you can start chatting with zero setup — no API key needed.

🛠️ 40+ Tools — Beyond Chat

• Notifications — triggered push alerts
• Location & Time — context-aware responses

🖥️ Interactive UI Mode
Go full-screen. In Interactive Mode, Kai 9000 becomes a visual app builder — no markdown, no scrolling text. Just tappable, functional screens generated on the fly. Navigate entirely through buttons and inputs. It's like having a personal app developer in your pocket.

🔒 Privacy-First, Open Source & Ad-Free
All chat history is encrypted and stored locally on your device. No ads, no data collection, no tracking. API calls go directly to your chosen provider — Kai 9000 never sits in the middle. Run local models for a fully offline, private experience. Fully open source, fully transparent.

🌍 Works Everywhere
Use Kai 9000 on your Android phone, tablet, Chromebook, or desktop. Your assistant, always within reach.

Whether you're writing, coding, summarizing, translating, brainstorming, automating workflows, managing emails, or studying — Kai 9000 is the free, ad-free, open-source ChatGPT alternative that adapts to you.
