An island floatsat the top of your screen.

Fuyu is a desktop island for Windows. Todos, clipboard, messages, translation, music and your AI agents live at the top of the screen. It opens when you need it and tucks itself away after.

One island, one whole day

  1. Today's todos, the one you're focused on, a daily note and the archive. Press Start to time it; collapsed, the island just says “3 todos left”.

  2. Text and image clipboard history. Tab cycles through starred, images, files, snippets and #tags. Drop files on the island to hold them, then drag them into another app.

  3. QQ, WeChat reminders and several mailboxes. New messages surface from the island and slip back after a glance; mail can be read and answered right there.

  4. Select text, press the shortcut, and the translation is right there, from the LLM translators you choose. No extra browser tab.

  5. Press the shortcut and the screen holds still. Click a window to take it, or drag an area; boxes, arrows, text, mosaic, numbers, then Enter copies it. Try it on the screen right here.

  6. Claude Code and Codex sessions light up on the island: working, waiting on you, asking for approval. Approve on the island; click a session to jump to its terminal.

  7. Control whatever is playing, with lyrics and a waveform that follow along. When nothing needs you, the island just sits quietly at the top.

With a few Claude Code and Codex sessions open, there's no need to flip through windows to see which one stopped. Working, waiting on you, asking for approval: the island tells you at a glance. Try the buttons below.

Ten sounds, one for each thing: you sent a message, it asks you something, it needs approval, it failed, it's done… a thumb piano Fuyu synthesises itself, so you can tell them apart by ear. Below is a stretch of a working session; turn the sound on and let it play.
