LocalEngine runs open-source AI language models entirely on your iPhone and iPad. Everything happens on-device: your prompts, conversations, and images never leave your device and are never sent to any server. Built in pure Swift with SwiftUI, LocalEngine runs models through a Metal-accelerated llama.cpp engine, so you get fast, low-latency AI completely offline — no account, no sign-in, no cloud. WHAT YOU CAN DO • Chat — Hold multi-turn conversations with a local model. Replies stream token-by-token in real time. Start a new chat or stop a response at any time. • See images — Turn on vision in Settings, attach photos to your message, and ask about them. Images are understood entirely on-device by a vision-capable model. • Download models — Browse a curated catalog of open models and download the one that fits your device. Downloads run as resumable background jobs with live progress, and the screen can stay awake while a large model downloads. • Tune generation — Adjust the response length (max tokens) and the temperature to shape how the model replies. • Unlock larger models — LocalEngine is free to use with starter models. A one-time Pro upgrade unlocks larger catalog downloads on iPhone and iPad. CURATED MODELS LocalEngine is ready to chat out of the box with a small, fast default model, and its catalog includes compact vision-language models you can grow into: • Qwen3.5 — 0.8B and 2B free, with 4B available through Pro • Gemma 4 — E2B free, with E4B available through Pro Smaller models are quick and light on storage; larger Pro models are more capable on newer devices. Each vision model pairs with a multimodal projector so it can understand images — all on-device. PRIVATE BY DESIGN • 100% on-device inference — no cloud, no telemetry, no analytics. • No account and no sign-in required. • Runs fully offline once a model is downloaded. • Built to App Store privacy and security standards. REQUIREMENTS • iOS / iPadOS 17.0 or later • A recent iPhone or iPad is recommended, especially for the larger models • Free storage space for the models you choose to download LocalEngine puts the power of modern AI — text and vision — in your pocket, without giving up your privacy.
