| # L-AI — private AI chat that runs on your phone |
|
|
| **L-AI** is a free Android app by **UltraLabs** for chatting with AI models that run **fully on your device**. |
| No account and no cloud. Your chats never leave your phone unless you turn on a feature that needs the internet, such as web search. |
| It runs any **GGUF** model through a fresh build of llama.cpp. It also runs many older GGML `.bin` models that other apps no longer load. |
|
|
| 📥 **Download:** [`L-AI-1.17.apk`](./L-AI-1.17.apk) (65 MB) · Android 11+ · 64-bit ARM (arm64-v8a) |

| ## Highlights |
|
|
| - 🧠 **Any GGUF model.** Qwen, Llama, Gemma, Phi, LFM, Mistral, MoE models and more. Each model is formatted with its **own chat template**, so it behaves the way its makers intended. |
| - 🗂️ **Older models too.** Legacy GGML `.bin` files are detected and loaded automatically: LLaMA (GGJT/GGMF/ggml), GPT-2, and GPT-NeoX (StableCode, StableLM-alpha, Pythia, Dolly, RedPajama). |
| - 👁️ **Vision.** Attach photos from the gallery or camera and let vision models (with an `mmproj` file) describe them. Downloading a model from Hugging Face grabs its projector automatically (Q8, else F16). Keep several projectors: each model is linked to the one that actually fits it (checked from the files), and nothing loads while Vision is off. |
| - 💡 **Thinking models.** A 💡 button turns reasoning on or off. It only appears for models that support it. A thinking budget cuts long thoughts short, and the reasoning is shown in a collapsible "Thought process". Qwen3.5 reasoning models are detected from their metadata and their <think> block is opened for them, the way they expect. |
| - ⚡ **Speed tools.** |
| - Speculative decoding with a draft model. |
| - MoE expert offloading and prefetching. |
| - KV cache quantization (f16 / q8_0 / q4_0) and flash attention. |
| - Memory-mapped or in-RAM loading. |
| - A built-in benchmark (prompt processing and generation). |
| - 🔧 **Tools the model can call** (native tool calling): |
| - Web search (DuckDuckGo / Wikipedia). |
| - A calculator that gives exact results. |
| - File creation. |
| - 📚 **Knowledge.** Add TXT / PDF / EPUB files. The most relevant passages are found and given to the model. |
| - 🧷 **Memory.** The model can remember facts you tell it across chats. You can view or delete them anytime. |
| - 🎭 **Personas and slash commands.** `/summarize`, `/translate`, `/eli5`, `/fix` and your own custom ones. |
| - 💬 **A chat experience you'd expect:** |
| - Markdown, code blocks with copy and **Run** (live HTML/JS preview), charts, Mermaid diagrams and LaTeX. |
| - Regenerate with versions, edit and resend, fork a chat from any message. |
| - Read aloud, voice input with optional auto-send, and haptic ticks while it writes. |
| - ✨ **Instant follow-up suggestions** after each reply. They're worked out on the device without using the model, so they cost nothing. |
| - 🏷️ **Automatic chat names** from a tiny bundled titling model (about 20 ms, no setup). |
| - 🕶️ **Temporary chats** that are never saved or remembered. |
| - 🗃️ **History:** |
| - Search, folders, pins, share and export (.md / .txt). |
| - Backup and restore. |
| - 🔌 **Integrations:** |
| - An **OpenAI-compatible API server** on your local network, so you can use your phone's model from a PC. |
| - A **remote server** option: chat with a bigger model running on your PC (llama.cpp, LM Studio, Ollama, Jan, Atomic Chat or any OpenAI-compatible server). With Tailscale it works from anywhere, and replies stream in live. |
| - Share-to-L-AI, a Quick Settings tile and a home-screen widget you can resize from a tiny icon up to a big panel. |
| - 🎨 **Make it yours:** |
| - Material You or custom colors, 9 presets and AMOLED black. |
| - Bubble / card / minimal chat styles, fonts, text size and chat wallpapers. |
|
|
| ## Getting started |
|
|
| 1. Download **`L-AI-1.17.apk`** above, open it, and allow installing from your browser or file manager if Android asks. |
| 2. Open L-AI, tap the model library, then either: |
| - **Download from Hugging Face** inside the app (search any GGUF repo), or |
| - **Add a model file** you already have (`.gguf` or `.bin`). |
| 3. Load it and start chatting. That's it. |
|
|
| **Which model should I try?** On most phones, a 0.5B–4B model at Q4/Q8 is the sweet spot. |
|
|
| | Phone RAM | Good model sizes | |
| |---|---| |
| | 4 GB | up to ~1.5B (Q4) | |
| | 6–8 GB | up to ~4B (Q4) | |
| | 12 GB+ | 7–8B (Q4), or small MoE models | |
|
|
| Small models from the same creator work well: |
| - [GRAFT-1B](https://huggingface.co/SmallAICreator/GRAFT-1B) |
| - [GRAFT-1B-Vision-GGUF](https://huggingface.co/SmallAICreator/GRAFT-1B-Vision-GGUF) (with image support) |
| - [MiniGPT2-22M-GGUF](https://huggingface.co/SmallAICreator/MiniGPT2-22M-GGUF) (tiny, for fun) |
