Box is a private open-source local AI workbench for the Linux desktop. Chat with text, images and audio, let a coding agent work on your projects, generate and edit images, and ask questions about your own documents , all on your own machine. No account, no telemetry: models download once, then run offline, you can also import models downloaded from huggingface.

Two inference engines

• Google's LiteRT-LM runs Gemma .litertlm models with vision, audio and native tool calling
• A bundled llama.cpp engine (CPU and Vulkan) runs GGUF models such as Gemma QAT and Qwen coders
• A built-in model hub downloads checksum-verified models in one click

Box Code — a local coding agent

Point it at a project folder and give it tasks. It explores, edits with exact-match patches, runs commands in a sandboxed shell with no network, and keeps a todo list. Choose Ask mode to approve each risky action, or Auto mode to let it work.

Image Studio

• Generate with Z-Image Turbo, FLUX.2-klein and Stable Diffusion 1.5 / 2.1
• img2img, inpainting with a paintable mask, hires fix and LoRA
• Erase objects with MI-GAN and upscale 4× with EDSR

Everything else

• Document Q&A: attach PDFs, Markdown or code; answers cite their sources. Notebooks keep reusable document collections
• Agent mode with web search (DuckDuckGo, no API key) and workspace file tools
• Audits of logs and configs, even ones larger than the context window
• Hands-free voice conversation with Piper text-to-speech
• Live camera vision
• Persistent memory you can review and delete
• Markdown, LaTeX and syntax-highlighted code in chat
• 52 themes, Glass and Liquid Glass modes, and 80 bundled fonts

You decide what runs, kill switches built in

Every capability starts switched off. Tools that touch your machine ask first, and file writes always ask. Inference servers run kernel-sandboxed with Landlock, inside the snap's own confinement, with no outbound network. App Lock protects the whole app behind a passphrase.

Optional permissions

Camera, PipeWire and external drives aren't connected automatically:

 sudo snap connect box-linux:camera
 sudo snap connect box-linux:pipewire
 sudo snap connect box-linux:removable-media

Note: Box Code's shell can only use the tools bundled in the snap, not compilers installed on your system. For full Box Code use, install the .deb from GitHub.
