Parallel timeline overview
A first example

Three giants. One year.

Three people whose names define the era, and most history books never put them on the same page.

1564
Three giants, one year.
Michelangelo
Galileo
Shakespeare

Galileo is born. Three days later, Michelangelo dies.
That same year, Shakespeare comes into the world.

Why I built this

History rarely tells you what else was happening. Parallel does.

Anatol Knotek

“Standing in front of a painting in a museum, I want to know: Who were the artist's contemporaries? Who was in power? What wars were being fought? What else was happening at the time? I want to understand the circumstances under which a work was created. Parallel is the tool I built for exactly those questions.”

Anatol Knotek · Vienna, 2026

The idea

Centuries at a glance. Details at a tap.

Most history is told as a single thread. One person, one period, one place.

Parallel layers multiple timelines on top of each other. Zoom out from a single year to 13.8 billion years, or zoom in until you can read every month. Swipe through thousands of years of history with a single gesture.

Double-tap any entry, and the app shows you who else was alive at the same time: Goethe was six when Mozart was born, and Beethoven died while Schubert was still composing.

Deep time

From the Big Bang to the present day.

Parallel shows much more than the last few centuries.

Zoom out until 13.8 billion years fit on your screen. The free Earth & Life collection fills them completely. The formation of Earth, the first life, the dinosaurs, the evolution of humankind. A single tap brings you back to your own century.

Who Parallel is for

A timeline for many uses.
