What's the idea behind Lexios?
Simply put, “Learn vocabulary effortlessly while browsing the web”.

An example is worth a thousand words. Let’s suppose you decide to learn German; read the following sentence:

- He went to Geneva aéroport to take his plane to Paris.

Here, without knowing a single word of French, you just guessed that "aéoroport" means airport from the context! That's ludic and did not require you any real conscious effort, yet you just learnt a new word.

How does Lexios work?
Lexios is a web extension for Chrome and Edge that translates words on the pages you visit. Hence you learn new vocabulary passively while browsing the web as usual.
We just released the MVP a few weeks ago, so please check it out at

Looks interesting but… does it give any actual proven results?
The first study on this concept shows results comparable or even better than standard methods such as vocabulary tables - while only inducing a slight slow down in reading speed. If interested, check out the study at

Next steps for Lexios
We just released Lexios MVP a few weeks ago and are now looking at growing it. There will be first the release of Lexios premium in the next two months, followed by new features and supported languages.

The team only consists of myself at this point in time, with the role of CTO and a strong focus on continuing to develop the product. There used to be another co-founder that filled the COO role and also took care of some of the marketing aspects. However, he did not want to continue with Lexios full time, leaving the spot wide open for anyone interested. Hence we are looking for one to two people with experience in marketing and operations to join Lexios full time. We did not have any funding yet; thus, you would get shares in the company and no salary.

Growth will be a crucial factor for the future of Lexios. That is why we would want to start looking at funding soon, once the team is complete.

Our Story
While I was still studying for my master at EPFL, I got in close contact with someone running a study on the concept behind Lexios: learning vocabulary effortlessly from context while browsing the web. I thought the concept was excellent and the final paper showed great promises. I thought that if I ever did a startup, it would have to bring this great idea to life!
At the end of my studies, I had the choice between pursuing the exciting startup path or take the safer path as a software engineer or data scientist in some company. You already know which path I choose...!
