Rather than a long video course, it is delivered as a sequence of short daily emails: you receive a lesson on a weekday morning, apply it to a real task that day, and return the next morning for the next building block. The structure is designed to break the loop of endless tutorials by forcing small amounts of deliberate practice. The curriculum moves through three broad arcs. It starts with how AI systems actually work and how to spot useful opportunities in your own role, then progresses to building: drafting, analysing, automating and prototyping with AI as a co-pilot, and finally to making AI a durable part of your daily rhythm through repeatable systems and habits. The goal is not tool trivia but judgement — the ability to pick up any AI product and use it competently. The challenge is oriented toward individuals but is also packaged for organisations that need to raise AI literacy across a whole team, with a sales-led track for company-wide rollouts. Because lessons are emailed, no software install or special account is required beyond signing up with a work email address. **Pricing & Plans:** The email challenge is free to join for individuals — you sign up with your name, company website and email. Team and enterprise rollouts are quoted separately through a sales conversation; specific team pricing is not published on the site. - **Daily emailed lessons:** A new short lesson lands in your inbox every weekday morning, so progress fits around a working day instead of competing with it. - **Three-phase curriculum:** Think with AI, build with AI and work with AI: a progression from fundamentals to automation to lasting habits, rather than a random tour of tools. - **Applied real-work tasks:** Each lesson asks you to use AI on something from your actual role, so you finish with artefacts and workflows you can keep using. - **Team programs:** Structured rollouts bring the same curriculum to a whole organisation with accountability and shared momentum, arranged via a sales conversation. - **Large peer community:** You learn alongside thousands of other professionals going through the same challenge, with supporting insights and case studies from 100 School. **Strengths:** Very low time commitment: roughly fifteen minutes per day, five days a week; Email delivery means no new app to install or platform to learn; Curriculum is practice-first, with tasks tied to your own real work; Free for individual learners, with a straight path to team programs **Limitations:** The current format is 15 days rather than the original 30, so expectations should be reset; No interactive live instruction is included at the individual level; Advanced or highly technical AI topics are out of scope [Profile (Markdown)](https://openaitools.app/tool/30daysofai.md) ## Code Arena Code Arena is built for developers who want evidence rather than marketing claims when choosing a coding model. Instead of reading benchmark tables, you prompt multiple frontier models with the same request, watch them construct web apps and sites in real time, and then judge the output on accuracy, logic, and code quality. The 'battle' format mirrors the popular blind-comparison leaderboard approach, adapted specifically for software generation tasks. The platform is designed to handle multi-file projects rather than single snippets, so the comparisons reflect the messy reality of real development work: routing, component structure, styling, and state management all have to hold together. Results are surfaced through a leaderboard so you can see which models are consistently favoured by the community over time. Because the tool is free to use and browser-based, it works well as a quick sanity check before committing a paid subscription or API budget to a particular model, and as a way to keep a finger on the pulse of how fast the coding-model landscape is moving. **Pricing & Plans:** Free to use; no paid tier is advertised on the product page. Related enterprise/API offerings from Arena may be priced separately. - **Model battles:** Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side. - **Real-time app building:** Watch models construct web apps and websites live, so you can see process and output, not just the final file. - **Multi-file generation:** Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together. - **Community leaderboard:** Track which coding models accumulate the most wins over time to identify consistently strong performers. - **Free browser access:** Run comparisons directly in the browser without installing anything or paying for credits. **Strengths:** Free, no-signup barrier for quick comparisons; Tests full multi-file projects, not just isolated snippets; Live battles reveal model behaviour, speed, and failure modes; Leaderboard aggregates community signal over time **Limitations:** Battles are subjective and depend on the prompts you write; Not a full IDE replacement for day-to-day development; Leaderboard results can shift quickly as new models ship [Profile (Markdown)](https://openaitools.app/tool/code-arena.md) ## Frequently Asked Questions ### How do 30DaysOfAI (100 School AI Challenge) and Code Arena compare in monthly traffic? 30DaysOfAI (100 School AI Challenge) has 26,006 monthly visits, while Code Arena has 35,827,928.
