Learn Python by being asked the right questions.
MiaCortex is a Socratic AI tutor that guides you through Python data structures and algorithms — so you build real understanding, not just answers.
No credit card required · 50+ problems free forever
Code, converse, and level up — in one window.
An IDE on the left, a Socratic tutor on the right. Run Python in the browser, get hints when you're stuck, and reflect when you ship.
# Problem 01 · Two Sum def two_sum(nums, target): # Mia: what data structure gives O(1) lookups? seen = {} for i, n in enumerate(nums): complement = target - n if complement in seen: return [seen[complement], i] seen[n] = i return []
target uses the same element twice?A learning loop that actually sticks.
Every feature exists to reinforce one thing: durable problem-solving skill, not autocomplete dependence.
Socratic AI Tutor
Instead of giving answers, Mia asks the right questions — guiding you to discover solutions yourself, the way the best teachers do.
Live Code Execution
Run Python directly in the browser with Pyodide. Edit, execute, and inspect output without leaving your lesson.
Progressive Hints
Stuck? Hints unlock gradually — never spoiling the journey, always nudging you forward.
AI Code Analysis
Get instant feedback on correctness, efficiency, readability and Pythonic style — line by line.
6 AI Personalities
Switch between mentors: Mia the patient, Lex the rigorous, Nova the playful — match your mood and learning style.
Test Case Evaluation
Every problem is graded against curated test suites — including edge cases — so you ship code that actually works.
From stuck to shipped in four steps.

“I'd grinded LeetCode for months and still froze in interviews. Two weeks with Mia and I finally understood why I was stuck — and how to think instead of memorize.”
“We piloted MiaCortex with our intro algorithms cohort. Engagement doubled and the discussion threads in office hours got measurably deeper.”
“The Socratic style is the closest thing to having a senior engineer pair-program with you at 2 AM. I recommend it to every new hire.”

Questions, answered.
ChatGPT gives you answers. Mia asks the questions that help you discover answers yourself. We deliberately limit code generation so you build durable problem-solving skills, not dependency on AI autocompletion.
No. Python runs in your browser via Pyodide — no setup, no environment headaches. Open a problem and you're coding in seconds.
The core curriculum spans arrays, strings, hashing, linked lists, trees, graphs, recursion, dynamic programming, and classical algorithms — calibrated for both university coursework and technical interviews.
Yes. Pro users can paste any prompt or assignment and Mia will tutor through it, generating hints and feedback in context.
Every submission is reviewed by Gemini against correctness, time/space complexity, readability and Pythonic style — with line-level suggestions you can apply or discuss.
Absolutely. The platform starts with Python basics and a gentle Socratic pace. Mia adapts her questioning depth to your level.
Your code and conversations are stored encrypted at rest, used only to power your own learning, and never sold. See our Privacy and Security pages for details.
