I recall seeing a unique language learning tool featured on HN awhile back. It stood out due to its innovative approach to demonstrating grammatical nuances between different languages. On the tool's homepage, translated sentences from a variety of languages are displayed. When you click on a sentence, a corresponding translation in another language is highlighted, showing how a sentence can be structured differently in languages. For instance, a sentence in Chinese may be represented by a sentence and some words in another sentence in English. it was stated to be in an early stage of development. By the time it appears on the top page, it is stated to still be in an early stage of development.

However, this tool seems to have slipped through my cyber grasp. Seeing Glossarie (https://news.ycombinator.com/item?id=39807912)) today reminded me of this tool and I wanted to check its current status. However, I couldn't find it despite trying various search terms such as "language learning", "multilingual" and so on.

If this rings any bells for anyone, could you kindly jog my memory on the name of this website or product and leave it in the comments? I would greatly appreciate it. Thank you!
