What is it?

Joke of the Day is a Chrome extension that serves you one joke per day. Click the icon, get a joke: a setup and a punchline. Simple.

Free users get a new joke every 12 hours, plus one free skip per cycle. Premium ($3.99 one-time) removes the wait and gives unlimited skips.

How it works

The extension pulls from three pools in rotation: monthly curated jokes (500 per month, seasonally themed), a general pool, and an infinite template-based generator that never runs out. You can use it every day for years without seeing a repeat.

The badge on the icon lights up when a new joke is ready. Chrome’s Alarms API wakes the service worker every 30 minutes to check, so the badge stays accurate even when the worker has been idle.
