Chiron
AI math tutor that asks, not tells, with Socratic hints to keep you thinking.
Chiron is a smart pick for iPhone users who want to actually learn math, not just get answers. Its Socratic hints build genuine intuition, but if you need quick solutions, broader subjects, or an Android app now, look elsewhere. For those committed to understanding, Chiron's guided approach stands out from answer-only apps like Photomath.

About Chiron
Chiron is an AI math tutor built on the philosophy of 'AI that does less.' Instead of revealing answers, it uses Socratic questioning to guide you through arithmetic to calculus with step-by-step hints that keep the thinking with you. Created by the Booth Brothers and backed by Y Combinator, the iPhone app offers a minimalist, distraction-free interface designed for students, self-learners, and tutors who want genuine understanding rather than quick answers. The free tier provides basic hints, while Pro unlocks unlimited practice, progress tracking, and offline access to previously solved problems. Unlike answer-generating apps like Photomath, Chiron keeps the thinking with you. Android is in closed beta, and schools and tutors are invited to connect for tailored discussions.
Behind the Verdict
Chiron's core value is its strict Socratic method: it never reveals answers directly, instead guiding you with hints that keep you thinking. This is a refreshing departure from answer-giving apps and aligns with educational best practices. The free tier gives you basic hints across arithmetic through calculus, making it accessible. Pro adds unlimited practice, progress tracking, and offline access, which are essential for serious study. However, the app is iOS-only for now, with Android in closed beta. There's no web or desktop version, so you're tied to your iPhone. Subject coverage stops at calculus, so linear algebra and differential equations are out. For advanced users or those on Android, this is a dealbreaker. Where it fits: high school and college students struggling with concepts, self-learners who want the 'why,' tutors who want to prompt deeper thinking, and parents helping kids without giving away answers. Where it doesn't: anyone needing quick solutions, symbolic computation, non-math subjects, or Android support now. If you need a broader math tool, consider Wolfram Alpha or Desmos, but for conceptual mastery, Chiron is a worthy investment.

Real-world workflow fit
Concrete scenarios for the personas Chiron actually fits — and what changes day-one when you adopt it.
You open Chiron on your iPhone and type a derivative problem. Instead of the answer, you get a hint asking you to identify the function type. You work through each hint, building the solution step-by-step.
Outcome: You complete the problem with a genuine understanding of the chain rule, ready for similar problems on the test.
During a session, your student is stuck on a quadratic equation. You use Chiron to prompt them with Socratic hints, guiding them to factor it themselves.
Outcome: The student gains confidence and internalizes the factoring process, reducing dependency on your direct answers.
Your child struggles with fractions. You open Chiron, enter the problem, and let the app guide your child through hints that keep them thinking.
Outcome: Your child solves the problem and learns the reasoning without you having to give away the answer, making homework time more productive.
Use Cases
- Work through a calculus derivative step-by-step with Socratic hints.
- Prepare for SAT math by practicing with guided questioning.
- Help a younger sibling understand fractions without giving the answer.
- Review algebra concepts before a test with unlimited problems (Pro).
- A tutor uses Chiron to prompt a student through a geometry proof.
Limitations
- Chiron is currently available as an iOS app for iPhone, with a closed beta for Android.
- The free tier may have restrictions on hints or frequency of use.
- Subject coverage spans arithmetic through calculus, so higher-level math (linear algebra, differential equations) is not supported.
- There is no mention of API, web, or desktop access, limiting you to the mobile experience.
