Private AI. On your device. Entirely yours.
Gemma 4 E2B · 4-bit · 100% on-device · MLX Swift
Sunday loads Google's Gemma 4 straight onto your iPhone's GPU through Apple's MLX framework. No sign-in, no servers, no waiting on a network — just local intelligence, ready in seconds.
Every conversation lives on your device and nowhere else. Start a new chat with a single tap — nothing is uploaded, nothing is logged, nothing ever leaves your hands.
It decides on its own when to reach for a tool — running the built-in calculator for exact math, or searching the live web for things like today's weather. Then it folds the result right back into its reply.
Send a photo and Sunday actually sees it. Ask what kind of tree that is and it reasons its way to the answer — Ponderosa Pine — with an optional thought process you can expand and inspect.
Drop in a PDF and Sunday reads it page by page, right on device. Ask for feedback on a report or a summary of a long file — it works through every page, no upload required.
Attach whatever you've got. Sunday transcribes voice memos and audio files, samples video frame by frame, and reads documents — all through the same private, on-device model.
Choose how thoroughly Sunday samples a video, how much of a conversation it remembers, and how it behaves by default. Power-user settings when you want them — never in your way when you don't.
Gemma 4 E2B, 4-bit quantized, ~2.5B effective parameters, a 128K-token context — all running in MLX Swift. Tune vision quality for sharper images, and paint the whole app in your color.
