I tried a chat section. It's pretty cool, I used another company that's very similar to yours but it didn't recognize speech nearly as well as yours does. The only negative feedback I have for you is the web app seems a little bit buggy on my phone sometimes when you click to hold down for speech it doesn't work very well you have to try it a couple times. I like it though I'm going to try it again.

The app looks interesting, but it's not free. The free version is very limited, and the premium version seems expensive, although it may be worth it.

@ClaviSay

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. All features are free, so feel free to use them as you like. You can also provide feedback at any time; ClaviSay offers a dedicated feedback channel. Thank you all.

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.
