TangiLM vs LocalEngine

TangiLM — Run AI Locally on Your iPhone TangiLM is a mobile language model app that lets you run powerful chat and reasoning locally on your iPhone. No account required, no cloud subscription, and no need to send your prompts to remote servers. Download your own GGUF models easily, manage them easily, and chat with full control over what runs on-device. Key Features Offline-first private chat Run your language model locally for everyday conversations, brainstorming, Q&A, and writing. Keep your data on your device to support a more private workflow. Download and manage local models Browse, download, and load your favorite GGUF models from Hugging Face. The app scans your model directory, tracks download progress, and lets you switch models anytime. Optional web search for up-to-date answers When enabled, TangiLM can perform web searches and pull relevant page content to help answer time-sensitive questions. This hybrid approach keeps casual chat fast while still supporting more current information when you choose. Built-in search workflow (analyzing → searching → evaluating → fetching) For improved relevance, the app uses an advanced internal agent loop to refine search queries, decide whether to fetch a page, and combine results into the final context used for generation. Thinking and searching controls If your selected model supports advanced reasoning, you can enable a “thinking” mode for better step-by-step answers. You can also toggle the web search feature per conversation. Fine-tuned performance and stability TangiLM also lets you fine-tune inference parameters for better speed and stability. For newer model releases, the app provides strong compatibility and optimized inference behavior, which helps reduce the likelihood of overheating and crashes commonly seen in other iOS AI tools. Session and history support Your chat sessions are saved automatically so you can continue where you left off. Review messages, edit user content, and keep your workflow organized. Multilingual UI and prompts The interface is localized across multiple languages, and the app supports multilingual prompts for smoother international use. Why TangiLM Whether you’re building a private assistant, experimenting with different models, or asking questions that benefit from fresh web information, TangiLM gives you a practical, flexible toolkit: local speed and privacy by default, with optional online search when you need it.

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.
