## 14DaysOfAI (100 School)

14DaysOfAI (now also presented as "15 Days of AI") is an email-based learning challenge run by 100 School. Instead of long video courses, it sends one compact lesson to your inbox every weekday morning, sized for roughly 15 minutes of focused practice. The curriculum is split into three arcs: thinking with AI, building with AI, and working with AI, so learners move from first principles to hands-on automation and prototyping.

The challenge is aimed at professionals rather than developers. Lessons mix explanation with concrete tasks, so you finish with working prompts, small workflows and an automation habit instead of just theory. 100 School also offers a teams track for organisations that want structured AI upskilling with accountability, and runs a newsletter plus additional courses on no-code and writing.

Because it is delivered by email, the format adapts well to busy schedules: there is no fixed class time, and you keep the lesson archive to revisit later. It is free to join the individual challenge.

**Pricing & Plans:** The individual challenge is free to join. 100 School sells a separate paid offering for teams; specific pricing is quoted on request.

- **Daily email lessons:** A new lesson lands in your inbox each weekday morning, designed to be completed in about 15 minutes.
- **Three-week skill arc:** Progresses from how AI models work, to building prompts and automations, to embedding AI into your daily workflow.
- **Task-based practice:** Lessons pair each concept with a real work task so you produce usable outputs, not just notes.
- **No setup required:** Everything runs through your existing email and whatever AI tools you already use; no installs or coding environment.
- **Teams programme:** A structured version for organisations that adds accountability and group capability building.

**Strengths:** Very low time commitment, roughly 15 minutes per weekday; Free to join the individual challenge; Practical, task-oriented curriculum rather than passive video; Delivered by email, so it fits any schedule and works on any device

**Limitations:** The daily drip format means you cannot binge the whole curriculum at once; Best results depend on actually doing the tasks, which takes discipline; Content is generalist, so specialists may want deeper technical material

## Brilliant

Brilliant takes a different approach to learning: rather than watching long videos or reading dense textbooks, you build understanding by solving interactive problems. Lessons break big ideas down into small visual steps, so concepts in algebra, calculus, statistics, logic and Python become intuitive. The platform is designed for self-paced learners from roughly middle-school level up to college and beyond, and it adds a new AI tutor called Koji who asks guiding questions and sketches on screen to help you find answers yourself.

Beyond pure math, Brilliant covers computer science fundamentals, programming, data analysis and how modern AI actually works, including neural networks, tokenization and model reasoning. Each track uses mastery assessments that adapt to your level, revisiting weak spots and serving targeted practice so progress is measurable rather than vague. Real-world examples, such as image filters or password security, connect abstract ideas to everyday technology.

The platform is also used by schools and families. It is accredited by ACS WASC, certified under the kidSAFE/COPPA program, and offers classroom and teacher programs so educators can assign adaptive lessons and homework. For individual learners, the app is available on web and mobile, with progress syncing across devices.

**Pricing & Plans:** Brilliant uses a freemium model: a limited free experience is available, while a Premium subscription unlocks the full course library and unlimited practice. Annual plans are the cheapest per month, and there are separate school/classroom plans.

- **Interactive problem-based lessons:** Learn math, science, CS and AI through short, visual exercises that build intuition step by step rather than passive video watching.
- **Koji AI tutor:** A visual, interactive tutor that works on a shared canvas, asks guiding questions and gives hints without simply revealing the answer.
- **Adaptive mastery assessments:** Quizzes and reviews adapt to your level, tracking what you have mastered and resurfacing topics that still need work.
- **Coding and CS foundations:** Write and run real code to learn programming logic, algorithms, data structures and debugging skills relevant to the AI era.
- **Courses for schools and families:** Accredited classroom programs let teachers assign adaptive lessons, with kidSAFE/COPPA-certified privacy protections.

**Strengths:** Hands-on, visual format makes abstract concepts easier to grasp; Access to the Koji AI tutor that guides rather than gives away answers; Accredited and kidSAFE/COPPA certified, suitable for schools and families; Works across web and mobile with syncing progress

**Limitations:** Full course library requires a paid Premium subscription; Not a replacement for formal instruction or credentials; Some advanced or niche topics are not covered deeply
