TenX
Read full descriptionHide full description
No more apps that just hand you the answer. TenX is an AI study coach that solves problems across every subject—math, English, science, and more—from a single photo. Instead of giving you the answer, it guides your thinking so you build the ability to solve problems on your own. ※ Just snap a photo to begin Take a picture of a problem or pick one from your gallery. AI automatically recognizes equations, diagrams, and text, then sorts each problem by subject, topic, and difficulty. Whatever the subject, one photo is all it takes. ※ Step-by-step guidance — the process, not just the answer TenX won't simply tell you the answer. Instead, it asks: "What are we trying to find here?" "Which concept do you need?" "What's the first step?" It responds to your answers with feedback and naturally guides you to the next step—like having a tutor sitting right beside you. ※ Socratic hint system Stuck on a step? No problem. Hints come in three levels: Gentle hint: points you in the right direction. Strong hint: suggests a concrete approach. Full walkthrough: shows the entire solution, step by step. You get every chance to solve it yourself, with the right help exactly when you need it. ※ Mistake analysis and concept connections Wrong answers aren't just brushed aside. AI diagnoses exactly why you missed it—whether it was a calculation slip or a gap in understanding—and recommends the prerequisite concepts you need to shore up. It also serves up similar problems so you can turn weak spots into strengths. ※ Automatic mistake notebook Every problem you miss is saved automatically, building your own personal mistake notebook. See your weak areas at a glance and review efficiently before a test. It's the perfect review tool for exams, quizzes, and finals. ※ Visualize your thinking Understand the problem → organize the conditions → choose a strategy → calculate → verify. TenX maps out the entire solution process visually, so you can see exactly where you got stuck. ※ Who it's for Middle schoolers who know the concepts but struggle to apply them High schoolers who need to study efficiently with limited time Students who keep making the same type of mistake Anyone who wants to learn independently, without a tutor or paid lectures ※ What makes TenX different Most apps show you the answer and the solution the moment you enter a problem. Convenient—but that alone doesn't build real skill. TenX puts your own thinking and problem-solving at the center. AI here isn't a tool that hands you answers; it's a coach that builds your reasoning. Learning, in the end, is something you do yourself. TenX is with you every step of the way. ※ Terms of Use: https://www.silmaril.io/en/projects/tenx/terms ※ Privacy Policy: https://www.silmaril.io/en/projects/tenx/privacy
