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) ## Prep Edu Prep Edu is built around the idea that most test takers fail to raise their band scores not because they lack information, but because they get too little active practice and almost no feedback. The platform pairs a conventional course library — IELTS, TOEIC, HSK and a PrepTalk English conversation track — with AI environments where learners actually speak and write and then immediately see how they performed. The AI Virtual Speaking Room and Virtual Writing Room are the centre of that loop, scoring responses and commenting not only on grammar and pronunciation but on ideas, logic and vocabulary choice. A second layer is guidance. Teacher Bee AI acts as a 24/7 learning companion, helping learners move through lessons and unblock difficult tasks between scheduled study sessions. Prep also bundles entry tests, mock exams, progress tracking and study-roadmap tools so learners can see where they stand relative to their target score. The product is aimed squarely at exam-oriented learners who study from home — students and working professionals preparing for IELTS, TOEIC or HSK in Vietnam and across Southeast Asia, where the platform is actively expanding through education-technology events and institutional partnerships. Teacher and institution support is also part of the offering, with teacher-facing tools marketed alongside the learner experience. **Pricing & Plans:** Paid, course-based. Prep Edu sells structured IELTS, TOEIC, HSK and PrepTalk English packages rather than a single flat subscription, and the exact fee depends on which program and length you choose. Current prices are shown on the course pages after you select a track, so treat any figure you see in older reviews as potentially out of date. - **Prep AI Virtual Speaking Room:** Rehearse exam-style speaking tasks with AI scoring and multi-layer feedback covering grammar, pronunciation, fluency, vocabulary and how well your ideas are organised. - **Prep AI Virtual Writing Room:** Submit written answers and receive automated scoring with suggestions on structure, vocabulary range and accuracy to raise your band score. - **Teacher Bee AI companion:** A companion that answers questions, walks through difficult tasks and keeps learners motivated between lessons. - **Structured courses and mock tests:** Structured IELTS, TOEIC and HSK programmes, a PrepTalk English speaking course, entry tests and mock exams that mirror the real format. - **Personalised roadmap and mobile app:** A personalised learning path, daily progress tracking, score reporting and the Prep app for studying on the go. **Strengths:** Combines real course content with AI speaking and writing practice in one place; Feedback covers ideas, logic and vocabulary, not just surface grammar correction; Large active learner base with a well-known presence in the Vietnamese exam-prep market; Works fully online and via app, suited to studying at home on a flexible schedule **Limitations:** Course pricing varies by program and is not fully transparent until you talk to sales or log in; Heaviest focus is on IELTS/TOEIC/HSK, so it is not ideal for learners targeting other exams or general fluency only; Effectiveness still depends on learner discipline; AI feedback on ideas and logic is helpful but not a substitute for expert human tutoring; Some testimonials and score banners are marketing-heavy, so results should be judged against your own baseline and study time [Profile (Markdown)](https://openaitools.app/tool/prep-edu.md) ## Frequently Asked Questions ### How do 30DaysOfAI (100 School AI Challenge) and Prep Edu compare in monthly traffic? 30DaysOfAI (100 School AI Challenge) has 26,006 monthly visits, while Prep Edu has 1,414,975.
