About

LocalEngine

Features
Read full description

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 β€” no account, no sign-in, no cloud. WHAT YOU CAN DO β€’ Chat β€” 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. β€’ See images β€” 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. β€’ Download models β€” 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. β€’ Tune generation β€” Adjust the response length (max tokens) and the temperature to shape how the model replies. β€’ Unlock larger models β€” 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: β€’ Qwen3.5 β€” 0.8B and 2B free, with 4B available through Pro β€’ Gemma 4 β€” 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 β€” all on-device. PRIVATE BY DESIGN β€’ 100% on-device inference β€” no cloud, no telemetry, no analytics. β€’ No account and no sign-in required. β€’ Runs fully offline once a model is downloaded. β€’ Built to App Store privacy and security standards. REQUIREMENTS β€’ iOS / iPadOS 17.0 or later β€’ A recent iPhone or iPad is recommended, especially for the larger models β€’ Free storage space for the models you choose to download LocalEngine puts the power of modern AI β€” text and vision β€” in your pocket, without giving up your privacy.
