I’m the developer of ClaviSay, and I’ve always struggled with learning foreign languages. But since I need to use them for work, I wondered if I could create an AI that would help me read more efficiently and save unfamiliar words—all while I’m actually reading content like BBC or Medium. Now I’ve made it happen—ClaviSay.

I use Clavisay to save words and phrases while reading online without breaking my flow. What I like most is that everything keeps its original context, so reviewing later feels much easier than memorizing isolated flashcards.
The AI explanations are helpful when a simple translation is not enough. It feels like turning normal reading into language practice.
