I built this because I kept losing focus to vocabulary lookups.

The wrong answers. Google Translate gives you a word — but not the understanding. When I read ‘relief’ in a legal case, I don’t need ‘a feeling of relaxation’ — I need the legal remedy. Contextual definitions create real neural connections. Your brain maps new vocabulary to what you already know, but only when the explanation matches the context you’re reading.

The broken flow. Every time I opened Google Translate, I lost my train of thought. Moving to a phone, switching tabs, copying text — each lookup fragmented my deep work. I needed definitions to appear right where I was reading, without breaking the flow.

The procrastination. The hardest part wasn’t the reading itself. It was the fear of starting — knowing I’d hit words I didn’t understand and lose momentum. So I built Study Sheet: extract all the hard vocabulary from a page before you read it. Prepare first, then read without interruptions. Deep work becomes possible.

Before AI, this wasn’t possible. Now it is.
