TensorChat vs LocalEngine

TensorChat is a privacy-first AI chat app built for people who want AI that stays in their hands. Download models to your device, chat locally, and keep going even when you’re offline. Choose the model that fits your needs, start multiple conversations, and switch between threads anytime. Responses stream live for a fast, natural chat experience, and your chat history stays available on your device. Use text, voice, and images in one app. Supported models can understand image inputs, voice tools let you speak naturally, and text-to-speech helps you listen to responses hands-free. TensorChat is designed for local-first AI: • On-device AI by default • Download and manage models in the app • Offline chat after setup • Multiple chat threads with saved history • Voice input and text-to-speech • Image understanding with supported models If you want a private, flexible AI assistant without depending on the cloud by default, TensorChat gives you a more personal way to chat.

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.
