What Is The Kingdom of English?

The Kingdom of English is a web-based English language practice platform designed for ESL (English as a Second Language) and EFL (English as a Foreign Language) contexts. It was created in 2023 by David Satler, a teacher with more than a decade of classroom experience teaching English in Austria.

The platform was built to address specific problems that ESL and EFL teachers face when using generic digital tools: complicated setup processes, poor homework accountability, limited content coverage, and pricing models designed for institutions rather than individual teachers. Every feature was designed from direct teaching experience rather than market research.

The platform runs entirely in the browser. There is no app to download. Students and teachers access it at thekingdomofenglish.com on any device with a modern web browser.

Who Is The Kingdom of English For?

ESL and EFL Teachers

The teacher account is designed for individual ESL and EFL teachers who need to manage student practice outside of class time. Teachers can create up to 60 student accounts, assign specific exercises across all skills, track completion and scores, and use leaderboards to maintain student engagement. The teacher dashboard provides a complete view of each student's progress across grammar, reading, listening, writing, and vocabulary.

Individual English Learners

The individual account provides full access to all practice content for self-directed learners. This includes all 60 grammar topics, all reading and listening exercises, writing practice with AI feedback, vocabulary training, and the language games. Progress tracking and gamification features are included.

English Levels Covered

The platform targets B1 to C1 levels on the CEFR (Common European Framework of Reference for Languages). This covers intermediate through upper-intermediate and into advanced English. Grammar topics include areas such as present perfect vs past simple, reported speech, passive voice, conditionals, relative clauses, gerunds and infinitives, articles, and prepositions.

What Content Does It Include?

Grammar Practice 60 topics covering B1 to C1 grammar. Exercises include gap-fill, sentence transformation, and multiple choice. Teachers can assign specific topics.
Reading Comprehension 60 reading texts with comprehension questions. AI evaluates open-ended written responses, not just multiple choice answers.
Listening Comprehension 60 audio exercises with comprehension tasks. AI evaluates written answers to listening prompts.
Writing Practice Writing exercises with detailed AI feedback on grammar, structure, and content. Teachers can review submissions and AI feedback.
Vocabulary Training Structured vocabulary building exercises with tracking and progress measurement.
Language Games 4 games: Noun/Verb/Adjective, Birds with Letters, Chest of Letters, and Kingdom's Secret Words. Designed for vocabulary and word recognition practice.

How Does AI Feedback Work?

The Kingdom of English uses AI to evaluate student responses in three areas: reading comprehension, listening comprehension, and writing practice. Unlike platforms that rely solely on multiple choice questions, The Kingdom of English requires students to write their answers in their own words.

For reading and listening exercises, the AI evaluates whether the student's written response demonstrates genuine understanding of the text or audio passage. This provides a more accurate assessment than selecting from predetermined options.

For writing practice, the AI provides detailed feedback covering grammar accuracy, text structure, vocabulary use, and content quality. Teachers can review both the student's writing and the AI's feedback through the teacher dashboard.

How Does the Teacher Dashboard Work?

The teacher dashboard provides per-student and per-class visibility across all skills. Teachers can see:

Teachers create student accounts directly from the dashboard. Students do not need their own email addresses to join. The setup process is designed to get an entire class connected within minutes, not hours, and the assignment workflow makes it practical to turn that setup into regular homework and follow-up.

How Does the Gamification System Work?

The platform uses four gamification mechanisms to maintain student engagement over time:

How Much Does It Cost?

The teacher plan includes up to 60 student accounts at no additional per-student cost. Both plans include full access to all content, features, and games. All plans start with a 7-day free trial. No credit card is required to start the trial.

Its advantage is that every feature was designed specifically for the ESL and EFL classroom by a working teacher, with affordable pricing aimed at individual teachers rather than institutional licensing.
