Mouse Sprite — AI Learning Companion

Floating AI tutor on every page: drag-to-explain, stall prompts, local history. Bring your own OpenAI-compatible API key.

Mouse Sprite is a floating AI learning companion that follows you across every webpage — ready to help the moment you get stuck on a concept. 🎯 Drag-to-explain — highlight any text on any page, click the floating button, and get a contextual AI explanation without navigating away. ⏱️ Stall detection — when your cursor pauses longer than usual, the sprite gently asks if you need a hand. 💬 Ask anything — click the sprite to open a panel and type any question you have about the page. 🕒 Local history — every question and answer is stored on your device so you can revisit and learn from your own queries. ✨ Adaptive recommendations — concepts you keep returning to are surfaced as review suggestions. 🔑 Bring your own API key —Add your own key 🌐 Languages — UI in English and 简体中文, auto-detected from your browser locale or switchable from the settings page. 🔒 Privacy first — all settings and history live only in chrome.storage on your device. Mouse Sprite never uploads your queries, keys, or any other data to a server of ours. Your questions go directly from your browser to the LLM endpoint you chose — exactly as if you were using that provider's own site. Built for students, lifelong learners, and anyone who reads technical content online and wishes they had a patient tutor nearby.
