Nexural

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.

Verdict
The clearest difference is ads: Nexural at none against ChatBrain's shown. ChatBrain's advantage is update cadence (every 2 days vs every 4 days) and ratings volume (11 vs 1). On price, rating, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. ChatBrain sells 4 in-app purchases, starting at $3.99 per 7 days and Nexural sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for ChatBrain against 5.0 for Nexural. That said, the two scores are not equally well evidenced: ChatBrain has 11 ratings behind it against 1, so its average is the more settled of the two.
ChatBrain ships an update every 2 days, Nexural every 4 days. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
