The story behind Didu

We're building a global habit of getting smarter.

I started Didu because I was tired of spending hours on my phone and feeling emptier afterwards. I wanted something that took under 2 minutes but left me thinking for hours.

Every drop is written by humans. Researched, fact-checked, and sourced — not generated by AI. We consult scientists, read papers, and obsess over getting the nuance right. Because you deserve to share what you learn with confidence.

Didu is a small team in Copenhagen with a big ambition: to make curiosity a daily habit for millions of people. One drop at a time.
