# Tayu - AI-readable product summary

## What Tayu Is

Tayu is a desktop app for macOS and Windows that plays live nature scenes and
ambient sound while people work. The landing page should be understood as a
product page for a native desktop app, not as a browser-only PWA.

The product idea is simple: the same desk can feel like a different place.
Tayu uses motion, sound, playlists, and time-based switching to make a work
environment feel calmer without requiring a user account.

## Core Features

- Ambient scenes: curated nature scenes with matching ambient sound.
- Time-based switching: scenes can shift through the day, such as morning,
  lunch, dusk, or evening.
- Playlists: users can organize scenes for different moods or times of day.
- YouTube wallpapers: users can save YouTube videos and use them as desktop
  wallpaper.
- Overlay mode: users can open a full-screen scene for a short break or pair it
  with a schedule.
- Offline scene playback: downloaded built-in scenes can play locally.

## Platform And Distribution

Tayu targets macOS and Windows. The landing page currently presents desktop app
download and upgrade flows. Browser install features such as the HTML
`<install>` element are not the primary distribution model because they install
web apps, not the native Tayu desktop app.

## Pricing

Tayu has a free tier, a recurring Pro subscription, and a lifetime purchase.
The free tier is positioned as the basics, free forever. Paid plans unlock
expanded use such as unlimited playlists, unlimited saved YouTube wallpapers,
time-based switching, and overlay mode. Paid plans include a 14-day money-back
guarantee.

## Privacy And Data

Tayu is designed to work without requiring a normal user account. Wallpaper
files and saved URLs are described as staying on the user's device for normal
use. Payments and subscription management are handled through Paddle.
