## 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

## 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
