I've developed a mobile-friendly version of a classic French academic dictionary, addressing the major usability issues of the original http://atilf.atilf.fr/tlf.htm and the company's subsequent, yet only slightly improved, version https://cnrtl.fr/definition/laid .

My version has been thriving for several years, reaching an impressive SEO peak of 30k visits per month. This is a significant achievement considering the hundreds of hours invested in web scraping and data processing, while the website itself only took around 20 hours to build. Unfortunately, I haven't been able to maintain it recently due to time constraints, causing a gradual decline in traffic. Nevertheless, the site remains free for everyone to use.

For those interested in the tech stack, it's a combination of React, Racket, and Rust.

I welcome any feedback and suggestions!
