TsuiuChat is a private, on-device AI chat app. The name comes from a dialect word for "freedom" - because that is what local AI should feel like. PRIVATE BY DESIGN No account. No server. Your conversations run entirely on your iPhone, powered by on-device AI models (Apple MLX). Nothing you type ever leaves your device unless you explicitly ask it to - a web search, or a cloud service you choose to configure yourself. FREE. FOREVER. NO USAGE CAPS. - Unlimited AI chat, fully on-device: no trial period, no daily limits - Private web search: news, weather, wiki, and general questions - Image generation via Apple Image Playground (on supported devices) - Bring your own server: connect to a self-hosted Ollama or LM Studio instance - 8 languages: English, Traditional Chinese, Simplified Chinese, Japanese, Korean, French, German, Spanish UNLOCK PRO YOUR LOCAL TAVERN (role-play) Chat with built-in characters, write your own personas, or run multi-character scenes. Start from a trending scenario template and cast your own characters into it, or import a character card from the community. KNOWLEDGE FREEDOM (private PDF library) Import PDFs and ask questions grounded in your own documents. Answers come with page citations, and with an actual screenshot of the cited page, so you can see the source for yourself instead of just a page number. Exportable too. MODEL FREEDOM Choose your own model per task, including larger, more capable local models downloaded from the community. FINE-TUNING FREEDOM Full control over generation parameters, plus cross-conversation memory, so the app remembers relevant facts across chats. CLOUD IMAGE GENERATION Bring your own API key. Unlock Pro with a single one-time purchase - no subscription, ever. Requires iPhone 14 or later (6 GB RAM or more) for on-device models to run well.

Verdict
The clearest difference is ads: TsuiuChat at none against Subai's shown. Subai's advantage is iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
