1
SetupMake an empty folder and open it in Claude Code

Create a folder such as sticky-notes. Open it in the Claude desktop app's Code tab, or run cd sticky-notes then claude in your terminal. ChatGPT and Cursor will also build this from the same prompt.

2
SetupCopy the whole prompt below and paste it in

All 254 lines of it. You do not need to read it or understand it — you are copying it, not studying it.

3
SetupWait a few minutes

It writes four files: index.html, style.css, app.js and themes.js. There is nothing to install and no questions to answer.

4
SetupDouble-click index.html

It opens in your browser and works completely. Add a note, tick it off, close the tab, come back tomorrow — everything is still there.

5
SetupBookmark it straight away

Drag the bookmark to your browser's bookmarks bar. A planner you have to hunt for is a planner you stop using.

Build **Life Sticky Notes**, a personal sticky-note wall that runs entirely in the browser.

## What it is

A single page that looks like a pinboard on a dark wall. I write a note, give it a deadline, and it
appears as a tilted, taped, textured piece of paper. Notes past their deadline are flagged in red.
Notes I finish sink to a section at the bottom. No server, no account, no sync — everything lives in
localStorage.

## Deliverables

Four files, no build step, no npm, no framework:

05 · Monetize it

How you can monetize it.

1
Sell it as a templateTidy it up and sell the download on a site like Gumroad for $29 to $49. There are no servers or monthly bills; 20 copies is about $600, 200 is about $6,000.
2
Charge monthly for sync and remindersKeep the free app whole and charge $4 a month for notes that sync across devices plus one daily reminder email. Costs run about $1/month at the start and about $65/month with a few thousand users; 100 paying customers is $4,800 a year, but at a 2-3% conversion rate that needs roughly 4,000 regular users.
