This feature would add a small, optional “Grammar” button next to LingQs or highlighted phrases. Tap it, and boom: a quick, plain-language explanation of the grammar behind that sentence, powered by a lightweight AI model (like OpenAI’s o3-mini). Still confused? Ask a follow-up question. “Why is this subjunctive?” “Could I use a different tense here?” The AI responds in real time, keeping you immersed and informed. Why This Matters • Keeps learners in the flow. No more bouncing between LingQ and grammar sites. Get the answers where you are, when you need them. • Deepens understanding. Grammar explanations turn passive reading into active learning. You’re not just guessing—you get it. • Feels like magic. Tap a sentence, ask why it works the way it does, and get an answer. It’s like having a personal tutor sitting in your pocket. Why Now? The tech is already here. Small AI models can handle this beautifully without slowing things down or breaking the bank. All LingQ needs is to build the bridge. This feature would instantly level up LingQ’s value—not just as a reading tool, but as a full-on language learning companion
