Brilliant

What is Brilliant?

Brilliant is a problem-first learning app for math, CS, data, and science. The AI-relevant path is courses such as Introduction to Neural Networks plus the probability, algebra, and 'thinking in Python' tracks underneath ML.

Free lets you sample the lesson style; the library, daily lesson habit, and (on current Premium copy) tutoring by Koji sit behind Premium. Brilliant's public subscribe page does not print a single global sticker in HTML; mid-2026 web checkout trackers list about $30/month or $240/year ($20/month effective) for an individual.

Group plans on brilliant.org/subscribe/group-plans list 3 seats for $33.99/month billed as one annual payment, plus $10.10/month per extra seat. App Store / Play prices can be different (some 2026 listings show ~$25/month or ~$150/year).

There is no GPU, no model API, and no certificate that replaces a Kaggle ranking or a DeepLearning.AI specialization.

A concrete walkthrough: use Premium for four weeks, then decide with a Kaggle notebook

Do the free Neural Networks teaser. If the click-and-reveal style feels like work you will repeat, take monthly Premium for one cycle (~$30) and finish the course plus a probability short.

In week four, open a Kaggle notebook and implement a tiny network on a public dataset. If you never opened Brilliant after day five, cancel before renewal — Brilliant does not typically refund unused weeks.

If the family will share, switch to the 3-seat annual group ($33.99/month billed as one payment) instead of three $240 individual years. Do not buy Premium because you wanted ChatGPT Plus; different product.

Key features

• Click-through interactive lessons instead of 40-minute videos
• Neural-networks plus math/CS/data paths that support an ML start
• Daily lesson and mastery sequencing on Premium
• iOS/Android/web with one subscription across devices (web vs store price can differ)
• Group/family seats: 3 for $33.99/month annual on the official group page
• Not a coding sandbox and not an LLM — Koji tutoring is in-app, not ChatGPT

How to get started

1. Finish two free lessons to see if the interaction style clicks — many people bounce
2. If you stay, buy annual web Premium (~$240) rather than $30 month-to-month
3. Do Neural Networks after a probability / algebra refresh, not as lesson one if those are rusty
4. Use it as intuition, then write real code on Kaggle or fast.ai
5. Families: the 3-seat group page is cheaper than three individual annuals if everyone actually logs in

Brilliant pricing

Free samples, then Premium. Web individual commonly ~$30/month or $240/year in 2026 trackers — confirm on brilliant.org/subscribe.

Official group: 3 seats $33.99/month billed annually, +$10.10 per extra seat. Mobile storefronts may differ.

No refund on partial periods is the usual policy; cancel in the same channel you subscribed (web vs Apple/Google).

Our take: Pay annual only after a week of daily lessons stick. This does not replace Kaggle or a coding course. If you want an AI assistant, that is ChatGPT — Brilliant will not write your model.

Use cases

• Building visual intuition for gradients and networks before PyTorch
• Filling holes in probability or algebra that block an ML course
• A daily 15-minute STEM habit that is not a YouTube binge
• A shared family plan for school-age math plus one adult CS track

Strengths and tradeoffs

Brilliant alternatives

• Elements of AI: Free conceptual AI overview from the University of Helsinki — no Premium paywall.
• Kaggle: Practice on real data and GPUs instead of scripted interactive problems.
• fast.ai: Code-first deep learning, $0, if you already want to train models.
• DeepLearning.AI: Lecture + certificate specializations, not daily puzzles.

Use Brilliant to build intuition. Use Kaggle to practice.

Use fast.ai or DeepLearning.AI to write training code. Use Elements of AI if you only need a free conceptual overview.

FAQ

Is Brilliant free to use?

Brilliant's plans: Free sample lessons; Premium unlocks the library (web ~$30/mo or ~$240/yr). Pricing and free-tier limits change over time, so check the official site above for the latest details.

What is Brilliant used for?

Interactive STEM lessons — Premium is a course library, not an AI tutor subscription like ChatGPT Plus.

Who is Brilliant best for?

Brilliant is a good fit for building visual intuition for gradients and networks before PyTorch, or filling holes in probability or algebra that block an ML course.

What are the alternatives to Brilliant?

Commonly compared alternatives include Elements of AI, Kaggle, and fast.ai, see the comparison above for how they differ.

How much does Brilliant cost?

A few lessons are free. Full access is Premium. Web checkout in 2026 is typically about $30 a month or $240 a year; a 3-seat group is $33.99/month billed annually. Confirm the price on the subscribe page for your country and store.

What's the best Brilliant alternative?

Elements of AI is the most commonly recommended swap: free conceptual AI overview from the University of Helsinki — no Premium paywall. Which one is actually best depends on which of those tradeoffs matters more for what you're doing.

How much is Brilliant Premium?

The subscribe page asks you to check out for a local price. Independent 2026 web trackers list about $30/month or $240/year. The official group plan is 3 seats for $33.99/month billed annually. Apple/Google prices can be lower or higher than web.

Is Brilliant an AI tool like ChatGPT?

No. It is a paid course library with interactive STEM lessons, including a neural-networks course. It does not host a general assistant or an API.
