Ollama Chat AI

Chat with AI from your Android phone — or from any browser.

Ollama AI Chat connects to your Ollama server or runs powerful language models directly on your device — Gemma 4, Qwen 3, DeepSeek R1 Distill, and Phi-4 Mini — with no data leaving your phone. Now with Web Chat Sync: open a browser on any computer, sign in with the same account, and continue your conversations in real time.

### 💻 NEW: Web Chat — Chat from Any Browser

No laptop app to install. Open the web chat page in any desktop or mobile browser, sign in with Google or your email, and all your threads appear instantly. Type a message and your Android phone receives it, runs AI inference (Ollama or on-device), and streams the response back to your browser in seconds.

- Phone offline? No problem — messages queue locally in the browser and dispatch automatically when your phone reconnects.
- Real-time model selector shows only models you've actually installed, and pre-selects the right one per thread.
- Phone presence indicator shows when your phone is online and ready.
