## What is Lull?

Tell the AI three words about your day. Get a personalized sleep story tonight. Voice synthesis from Apple's on-device models. Stories never repeat. No subscription for the first three stories. Designed to actually put you to sleep, not entertain.

Different from Calm: every story is custom-generated for you, never repeats. Lull writes a brand-new bedtime story tonight using your name, your city, and the slow calm thing you used to love. No two listeners ever hear the same one.

WHY IT WORKS
• Personal — your name, your city, your kind of calm woven into every page.
• Four kinds of nights — a slow village walk, a cozy small spaceship, a gentle unsolved mystery, the forest at the edge of waking.
• Eight narrator voices, paced for sleep. Lifetime unlocks Voice Clone so Lull can read tonight's story in your own voice.
• Sleep timer with smart auto-fade — five minutes of no interaction and the audio glides down to silence on its own.
• Quiet companion mode — type how the night feels and Lull replies like a slow friend on a late-night call. Local, no servers.

FREE — 1 personalized story per night, 4 base voices, sleep timer, companion chat.

LIFETIME ($99 once) — unlimited stories, all 8 voices, Voice Clone, Apple Watch controls, smart wake. Pay once, keep forever.

PRIVACY
Lull does not collect, transmit, or store your stories, your chats, your sleep data, or your voice. Everything happens on this iPhone. We do not run a server.
