## 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

## Coddy

Coddy is a web-based coding education platform built around doing rather than watching. Instead of long video lectures, learners work through short interactive lessons in the browser, then immediately apply what they learned in an integrated playground with a compiler or interpreter. The catalogue spans web development (HTML, CSS, JavaScript, TypeScript, React, Next.js, PHP, Django), general-purpose languages (Python, Java, C#, Go, Ruby, Kotlin, Lua), systems work (C, C++, Rust, Assembly, Verilog, Solidity) and mobile development (Flutter, Dart, Swift, SwiftUI).

Beyond single languages, Coddy organises guided learning paths that mirror real job roles: Software Engineer, Frontend Developer, Full Stack Developer, Backend Developer, Data Analyst, Data Scientist, DevOps Engineer and several game-development tracks for Unity, Godot and Roblox. There are also recently added non-programming subjects such as pre-algebra, algebra, geometry, trigonometry, physics, chemistry and chess, aimed at learners who want one place for both STEM coursework and coding practice.

Coddy can be started for free, and the platform uses a freemium model with premium plans for additional content and features. The site is protected by Cloudflare, so automated crawlers may be blocked while normal browsing works fine. Please check the official pricing page for current plan details, since we do not list prices we could not verify.

**Pricing & Plans:** Free to start with optional paid plans. Coddy uses a freemium structure with premium tiers for extra content, learning paths and playground features; exact current prices should be confirmed on the official pricing page.

- **Interactive lessons in the browser:** Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
- **Built-in playgrounds and compilers:** Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
- **Career-oriented learning paths:** Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
- **Daily challenges and gamification:** Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.
- **STEM subjects beyond code:** Maths, physics, chemistry and chess courses let learners practise quantitative subjects step by step alongside their programming track.

**Strengths:** Very broad catalogue covering web, systems, mobile, data, game development and even non-programming STEM subjects; No setup required: lessons and playgrounds run entirely in the browser; Guided job-role learning paths make it easier to know what to learn next; Free to start, so you can evaluate the teaching style before paying

**Limitations:** The huge number of tracks can be overwhelming for complete beginners deciding where to begin; Depth per topic may be lighter than a dedicated deep-dive course or textbook; Some premium content requires a paid plan, and pricing must be checked on the site
