Hi, my name is David Satler, and I'm the creator of The Kingdom of English. I've been teaching English in Austria for over 10 years, although I'm originally from Slovenia. Growing up multilingual gave me a firsthand understanding of what it takes to learn a language from scratch, the frustration of not finding the right word, the satisfaction of finally getting a grammar structure right, and the importance of consistent practice outside the classroom.
Throughout my teaching career, I worked with students at B1 through C1 levels according to the
Common European Framework of Reference for Languages (CEFR). I noticed the same problem year after year: coursebooks offered too few exercises per topic, and students had no structured way to practise between lessons. Homework was either worksheets that disappeared into schoolbags or generic apps that could not be tailored to what I was actually teaching in class.
That gap between what teachers need and what existing tools provide is what motivated me to build something better. I taught myself programming and dove deep into AI and natural language processing, driven by a single question: what if a platform could evaluate open-ended student responses, not just check multiple-choice boxes, and still give teachers full control over assignments and tracking?
I launched the first version of The Kingdom of English in January 2023 and immediately started using it with my own students. Their feedback shaped every feature that followed. Within the first year, the platform grew from a basic grammar exercise tool into a practice environment covering grammar, reading comprehension, listening comprehension, writing with AI feedback, and vocabulary training.
By 2024, I added gamification features (points, leaderboards, streaks, coins, and virtual rewards) because I saw how much more consistently students practised when there was a competitive, game-like element. I also built four original language games: Noun/Verb/Adjective, Birds with Letters, Chest of Letters, and Kingdom's Secret Words, each designed to reinforce language skills in an engaging format.
The platform uses different ways to check practice. Standard reading and listening activities have multiple-choice questions checked against stored answer keys. Reading RoboTeacher is a separate AI-supported reading activity. Writing uses AI feedback on spelling and basic grammar, followed by a final recheck of previously listed mistakes. AI feedback can be incomplete or mistaken. The
platform guide explains these differences, and the
writing guide describes the feedback workflow and its limits.
Today, The Kingdom of English serves ESL and EFL teachers and individual learners. Teacher accounts have two class slots, with up to 30 learners in each class. Teachers can set class assignments and inspect separate overviews of recorded practice. These records do not by themselves establish language proficiency or learning gains; the
progress guide explains what the measures mean. Individual learners get full access to all exercises and games during a 7-day trial with no credit card required. Afterward, Grammar and Games remain available for free, while a subscription unlocks premium practice features.
I continue developing The Kingdom of English, including its software, design and teaching material. Some article drafting uses AI assistance, as disclosed in the notes on those articles. Preparing useful material also involves checking product descriptions, source information and worked examples, and correcting errors when they are found. Your use of this platform helps me keep developing and improving it further. Thank you for your support.
How our teaching articles are prepared
Authorship and AI assistance. Articles attributed to The Kingdom of English use an organisation byline. Recently updated guides, including the writing workflow, disclose AI-assisted drafting in their source notes. The personal biography above is separate from each article's authorship and preparation notes.
Dates and sources. Use an article's publication date, update date and source notes to understand when its information was prepared or checked. Notes on revised product guides identify checks against the current platform, while comparisons link to provider information. Features and access conditions can change. An update to one article does not mean every older article has received the same checks.
Worked examples. Examples labelled fictional are teaching material, not learner records, testimonials or measured classroom results. Their sample scores and counts illustrate a task or calculation; they are not evidence of learning gains.
Corrections. If you spot an error, use the contact and correction details. Include the article URL, the passage or problem, and a supporting source where possible.
