CloseAI

V2: SSH key auth, 5 AI models, full-text search, one-tap upgrades. Run AI on your own server — no subscriptions, no cloud, no data leaks.

CloseAI turns your own Ubuntu server into a private AI assistant you fully control. No subscriptions. No third-party relay. Your conversations never leave your infrastructure.

HOW IT WORKS

Connect CloseAI to any Ubuntu 24.04 VPS over SSH. The app remotely installs the full AI stack — Ollama runtime, a FastAPI backend, and TLS — directly on your server in minutes. After setup, all chat traffic runs encrypted between your iPhone and your server. You own every byte.

SETUP IN MINUTES

Choose how you connect: • Password setup — enter your SSH credentials, the app installs everything and automatically upgrades you to key-based auth afterward • Key setup — the app generates an SSH key pair on your device, you paste the public key into your VPS dashboard, done

Both paths run automated preflight checks, let you pick your starting model, and install the full stack remotely. If CloseAI is already installed, the app reconnects automatically.

CHOOSE YOUR MODEL

Five open-source models, install any combination: • Llama 3.2 (3B) — Fast, versatile, ideal for everyday use • Phi-4 Mini — Compact reasoning model from Microsoft Research • Gemma 3 (4B) — Highest quality output from Google DeepMind • Qwen 2.5 Coder (7B) — Specialized for code generation and debugging • DeepSeek-R1 (7B) — Chain-of-thought reasoning, strong at math

Switch models from the chat toolbar. The Ollama port is also exposed for direct use with Open WebUI, Continue.dev, and other compatible tools.

SEARCH YOUR CONVERSATIONS

Full-text search across all conversations and messages. Type a keyword and instantly find any message — tap to jump directly to it in context.
