About

Nexural

Read full description

Nexural is a privacy-first AI assistant that runs directly on your iPhone. Ask questions, write, summarize, brainstorm, and plan — without sending your prompts to a server for processing. WHY NexurAl • On-device inference: your prompts are processed locally during normal use • Works offline (after setup) • No accounts required • No training on your chats • Share only when you choose HOW IT WORKS Language models are the “brain” behind an AI assistant. NexurAl runs a model on your device (bundled with the app or downloaded in the app). Your text stays on your iPhone, and responses are generated locally. NEXURAL PRO (Subscription Required): Upgrade to unlock the full power of local on-device AI: - Premium Model Catalog: Access our full library of advanced, high-parameter models. - Pro Optimizations: Experience peak performance and security with Metal Acceleration, Speculative Decoding, Context Compression, Thermal Guard, Streaming Tokens, and the Encrypted Vault. PRIVACY IS THE FEATURE Many AI tools rely on the cloud. That can mean your private text is transmitted to servers and may be stored or used to improve models (depending on the provider). Nexural avoids that tradeoff by keeping AI processing on your device. IMPORTANT NOTE AI outputs can be inaccurate. Don’t rely on NexurAl for medical, legal, financial, or emergency decisions.
