NookYou made it with AI. Nook makes it last.
Vibe-code a tool in any AI, drop it into Nook, and it becomes a real app on your phone — one that remembers your data and still works next month.
No account to start · works offline · your app, your data
You know the feeling
You describe an app to an AI. A minute later it works — and it's genuinely yours.
Then you close the tab. A week later you want it back, and it's buried three chats deep, the shared link is dead, and the data you typed in never saved. The coolest thing you made all week — gone by Friday.
This is where it lives now — on your phone, right where you left it.
How it works
Make it anywhere. Keep it here.
Make it in any AI
Describe your tool to Claude, ChatGPT, or Gemini and get an app back — the way you already do.
Drop it into Nook
Paste the code. Nook runs it safely — plain HTML or React, no setup, nothing to install.
Keep & use it
It lands on your home screen, remembers your data, and works next month. Share one with your crew when you want.
Bring it from
Whatever you already use.
Get started
Keep what you make.
The things you make should be yours to keep. Start with an app you already have, or one of ours.
