Every morning until Christmas, a new door opens with something to build: an app, a website, an animation, an image or something made by hand. Each one is a small challenge to try something new.

How it works

A different build every day

Every door holds a different kind of thing to make. Some days you write code, some days you make an image, and some days you pick up a pen. You probably use AI to build the same kind of thing every day. This will challenge you to try something new.

  • APP
  • WEBSITE
  • ANIMATION
  • IMAGE
  • SKILL
  • MYSTERY TECH
  • BY HAND

  1. Get the prompt

    A new door opens every day at midnight, London time. Open it to read the brief and the steps.

  2. Build the thing

    Use Claude, your own tools, or pen and paper. Spend as much time as you have: five minutes is enough, and a few hours is fine too.

  3. Share it

    Post what you made on X, Bluesky or LinkedIn with #AdventOfClaude and the day's tag, then mark the door as built.
