Students, writers, researchers, and lifelong learners use Stemmy daily to expand their vocabulary naturally.
"Stemmy changed how I read online. I used to skip words I didn't know — now I actively seek them out. My vocabulary has grown tremendously."
"The spaced repetition actually works. I'm retaining words I learned weeks ago without any extra effort. It feels like the extension reads my mind."
"Great extension overall — the Ghost Card is magical and the AI definitions are superb. I wish it supported more languages beyond English. Would love to see multi-language support in a future update."
"I recommend Stemmy to all my students. It turns passive reading into active learning. The vocabulary wallet feature is incredibly motivating for them."
"Beautiful design, seamless experience. I love how the Ghost Card appears right where I'm reading — no context switching needed. Pure elegance."
"I read a lot of research papers and Stemmy has become indispensable. The AI-generated stories that use my saved words are surprisingly effective for memory."
