I built English Checker - a Chrome extension that helps non-native English speakers get better after their real-life online meetings.
It gives instant AI feedback: grammar mistakes, filler words, speaking speed, vocabulary suggestions, and an overall fluency score after every Google Meet call in funny Duolingo style.
I made it for myself after realizing how many “likes” and filler words I use on calls. It’s been super helpful to track progress over time.
Still very early, but if you struggle with English on calls like I do, maybe it can help you too. Would love any feedback!
