Explain it simply

Cursor is a code editor with AI built in. You describe what you want to build, and it writes and edits the code with you. It is the tool behind the browser game one founder built in an afternoon.

The tool behind the most-cited 'built it in an afternoon' story here. Some Cursor plans also include Grok Bot access.

Product

Ship a product in an afternoon with an AI code editor, then sell sponsor slots

Pieter Levels prompted Cursor into a browser flight simulator in about three hours and reported $1M in annualized revenue from in-game ads 17 days later.

How it went

Levels reported $87,000 in monthly revenue, a $1M annual run rate, 17 days after launch.

  • A run rate, not $1M collected.
  • Coverage pointed out that his roughly 623,000 X followers drove much of the demand.
  • A 2026 recap reports the game's revenue later fell to zero.

Build [product] as a single-page web app in plain HTML and JavaScript, with no framework.

Start with the smallest version someone can use in 30 seconds. Then list the next five improvements and wait for me to pick.

Add a "sponsor slot" component that reads advertisers from a JSON file, so I can sell placements without touching the code.

Best for

  • Shipping a web product or prototype fast
  • Founders who can read code even if they don't write much

Watch-outs

Know before you start

  • A fast prototype still needs distribution; the flight-sim example had a very large audience behind it

Pricing and access

Free and paid plans. Cursor Pro subscribers can use Grok Bot, per xAI's changelog (August 25, 2026).
