What having Sparky in your corner actually feels like
Explain a concept, summarize a chapter, generate a quiz, make flashcards, all from the same chat
Sparky is grounded in whatever you uploaded. Ask it to explain the second law of thermodynamics using your own lecture notes. Ask for a summary of chapter 3. Ask it to quiz you on what you just read. Everything it does connects back to your material, not the open web.
