The AI tutor that remembers what you get wrong

LemonSugar Ai turns a photo, typed question, or voice prompt into step-by-step tutoring—then checks whether the student actually learned it. Choose direct explanations, Socratic hints, or Feynman-style teaching in your language. Sugar remembers weak spots, builds custom quizzes, and resurfaces them before the next exam. Free forever for everyday homework; designed for learners 16+, from high school through graduate study.
Hey Product Hunt 👋
I built LemonSugar Ai around a simple frustration: most AI tutors help someone answer today’s question, then forget the learner tomorrow.
As a parent of two, I’m not worried about whether children will use AI—they will. I’m worried that a chatbot can produce a polished answer while leaving the learner unable to explain the concept the next day. I built LemonSugar Ai to make AI prove that learning happened, not merely that an answer was generated.
Sugar does the opposite. Ask with a photo, text, or voice. Choose a direct explanation, Socratic hints, or a Feynman-style walkthrough. Then Sugar checks whether the idea actually stuck, remembers the weak spot, and brings it back before the exam.
Before launch, 150+ users signed up for LemonSugar Ai, and 88 had already submitted a question and received a successful answer. The free plan includes 20 messages a week, and new users can try three questions before creating an account. Product Hunt members can also use code PRODUCTHUNT for 30 days of Thrifty free—no card and no automatic charge.
I’d especially value feedback on whether the memory loop feels meaningfully different from a general chatbot, what would earn your trust in an AI tutor, and which subject or exam we should make exceptional first.
I’ll be here answering questions and shipping fixes. Thanks for trying LemonSugar Ai 🍋
