A way to learn to code with an AI tutor that teaches you through a pathway, reviews the code you write, and brings every concept back on day 3, 7 and 18 so that what you learn stays learned.

There are 6 pathways: Python Foundations, JavaScript & TypeScript, Data Structures & Algorithms, Web Dev with React, Java & Spring Boot, Backend with Node.js. New modules are added as they ship, and every pathway is included in the one plan.

No. The tutor grades a short placement task and starts you at the right module. Concepts you learn in one pathway count in every other, so a new pathway skips what you have already mastered.

Regradia is not for children under 12. If you are under 18, you need a parent's or guardian's permission, and they agree to the Terms for you.

No. The tutor is an AI that runs on Claude, a model made by Anthropic. It can state things that are wrong or out of date and still sound confident, so test code before you rely on it.

It asks you to write the code, reviews it line by line, then has you explain the idea back in your own words. A concept is only marked mastered once you can.

Tutor sessions are unlimited within fair use: currently 100 messages a day and 3,000 characters per message. The tutor is for learning the Regradia curriculum.

Your messages and code are sent to Anthropic so that it can write the tutor's replies. By default Anthropic does not use them to train its models, and the tutor is not told your name or email address. Do not share passwords, payment details or other people's personal information in tutor chats.

Coming back to an idea just as it starts to fade is what makes it stick. The spacing effect is one of the most consistently replicated findings in memory research. Each concept you learn comes back three times, and a review session takes about 15 minutes.

A modern memory model from spaced-repetition research. Regradia uses it to estimate how stable each concept is and how likely you are to recall it today — the numbers on every review card. The review dates themselves are fixed: day 3, 7 and 18 after you learn a topic.

No. Reviews are scheduled on day 3, 7 and 18 after each topic either way, and wait in your daily queue. Connecting adds them to your calendar as all-day items, and you can disconnect at any point.

A missed review waits in your daily queue until you do it. If a review shows a concept has slipped, your roadmap can add a repeat of it, and it tells you why.

One plan, US$24.99 a month plus any tax that applies, after a 7-day free trial. It includes every pathway, the AI tutor, your roadmap and spaced reviews.

It keeps the AI tutor available to real learners. You are not charged until day 8, and you get a reminder 2 days before.
