LusoChat - AI Open Models

About this app

The whole frontier of AI, in one beautiful native app for iPhone, iPad, and Mac. LusoChat lets you chat with the best open-weight and frontier models side by side — and switch between them in a single tap. No API keys, no setup, no juggling a dozen subscriptions. ONE APP, EVERY MODEL Choose from a curated lineup of leading models — open-weight favorites like DeepSeek, Llama, Kimi, Qwen, GLM, and MiniMax, alongside frontier flagships from OpenAI and Google. Filter by Recommended, All, or Open models, see each model's strengths at a glance, and set your default. The lineup stays fresh automatically — no app update required. BUILT TO DO REAL WORK • Reasoning on your terms — dial thinking effort from Instant to High per message, and reveal the reasoning trace whenever you want it. • Web search built in — let models search the live web and cite their sources. • PDFs & images — attach a document or a photo. Images are compressed on-device, and PDFs can be read by every model. • Beautiful Markdown — answers render with clean headings, lists, and syntax-highlighted code blocks you can copy in a tap. • Library & Projects — save your favorite prompts and keep your chats organized. NATIVE TO APPLE Designed from the ground up for iPhone, iPad, and Mac with a bold, fast interface that feels right at home on Apple hardware. Sign in with Apple — or use it anonymously as a guest — and your chats, prompts, and projects sync securely across all your devices. PRIVATE BY DESIGN Your conversations are yours. LusoChat never uses your messages for advertising or to train models, and there's no tracking. Delete any chat — or your entire account — anytime. Download LusoChat and bring the whole frontier to your pocket.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
