About DailyBrainz

DailyBrainz is a free website for short daily brain exercises. It is run by a small independent publisher that builds simple online tools people can use for free, without an account.

What the site does

Every day, the site offers four short challenges. You can finish them in a few minutes.

• Daily Quiz: 5 questions on all topics.
• True or False: 10 statements, fast-paced.
• Guess The Number: see how close you can get.
• Timeline Challenge: put 4 events in the right order.

You enter your age at the start, and the challenges are adapted to it. New challenges appear each day.

You can also play topic quizzes whenever you like. The topics are science, history, nature, technology, space, geography, math and economics.

Who is behind it

The site is not run by a large company or a newsroom. It is made and maintained by a small independent publisher. We keep the tools simple, fast and free to use.

How the challenges are designed and checked

• Each question has one clear answer. We avoid trick wording and questions that depend on opinion.
• We check facts against reliable reference material before a question goes live.
• Dates, numbers and orders of events are re-read and checked a second time.
• When a reader reports a mistake, we review it and fix the question if it is wrong.

The quizzes are meant for learning and fun. They are not professional, medical, financial or legal advice, and your score says nothing about your intelligence.

How the site is funded

The site is free. It shows ads through Google AdSense, which helps cover the costs of running it. We also use Google Analytics 4 to understand how many people visit and which pages they use, so we can improve the site. Both services use cookies. Our privacy policy explains this in more detail.
