The story
behind
Leesje.

A conversation with Nick, the creator of Leesje — a Chrome browser extension to learn Dutch and build your vocabulary through reading, watching and practice. Born from his own experience as a learner.

With Nick, creator of Leesje

01 The beginning

What led you to create Leesje?

I’m Nick, I’m 28, and I started learning Dutch four years ago. One of the first challenges was finding the right resources. I tried different apps, but I didn’t feel I was making progress with them.

That was when I started thinking about building my own — something focused on practice and learning to use the language.

02 Keeping the words

What did you want to make easier?

When I read or watch a video in Dutch, unfamiliar words keep pulling me away from it. I look up a translation, write it on a piece of paper or somewhere else, and then forget it. My notes end up scattered around, and I never come back to practise the words.

In the end, a word becomes just another entry in my browser history. I wanted those words to stay with me, so I could return to them and practise. That’s the idea behind Leesje, and where our slogan comes from.

The idea behind leesje

Keep reading.
Keep watching.
Keep the words.
Words you find. Words you keep.

03 The learner

Who do you have in mind when you build it?

Someone who wants to understand and remember the words they learn. They might already feel confident in Dutch, or they might know ten words. I’m building Leesje to help people grow their vocabulary at different levels.

I want practice to go beyond memorising a translation. Understanding how words work in a sentence, including the grammar around them, matters to me too.

04 The practice

What does practice look like in Leesje today?

Right now, there are exercises for de/het, plurals, past tense, filling in the gaps, and word order. They give you different ways to practise vocabulary and grammar.

  • de / hetArticles
  • PluralsWord forms
  • Past tenseVerbs
  • Fill the gapWords in context
  • Word orderSentences

But this is only the beginning. I want to keep developing Leesje and add more ways to practise.

05 The name

And why “Leesje”?

Reading is at the heart of how you learn with the app. So I started with the Dutch word lezen — “to read” — and explored lots of variations around it. Eventually, those variations led me to Leesje.

The idea in everyday use

Learn Dutch.
Keep it in context.

Leesje brings reading, Dutch subtitles, vocabulary flashcards and grammar exercises into one learning tool. Here’s how the idea behind it becomes part of your day.

01 / Read

A browser extension to learn Dutch

Read a Dutch article, a news story or your own text. Leesje is a Chrome browser extension that highlights unfamiliar words and lets you look up their meaning where you find them.

Save a word with its sentence, so your Dutch vocabulary stays connected to something you actually wanted to read.

How to start with Leesje

02 / Watch

Learn from Dutch video subtitles

Explore videos with Dutch subtitles on YouTube, Netflix and Videoland. Click an unfamiliar word in the subtitles or follow the transcript to look more closely at a sentence.

Video gives new words a voice and a situation. Keep the ones you want to practise, then return to what you were watching.

03 / Remember

Dutch vocabulary flashcards with context

Your saved words become a personal collection for review. Vocabulary flashcards keep the original sentence alongside the word, helping you revisit its meaning in context.

Spaced repetition brings difficult words back sooner and familiar words later, so the words you discover have a place in your practice.

Practise de/het articles, Dutch plurals and past tense. Fill-the-gap exercises and word-order practice help you work with words inside a sentence.
