• 44 consonants module with tone class identification. This function presents each Thai consonant with its name, tone class (low, middle, or high), initial sound, and a visual example word. The student can listen to native pronunciation, view the writing order animation, and practice tracing. The purpose is to memorize both the shape and the sound value of every letter for building a solid reading foundation.
• 28 vowels and diphthongs system. This function breaks down all short vowels, long vowels, and diphthongs in Thai. Each vowel is shown in initial, medial, or final syllable position. The tool includes matching exercises where the user connects the vowel with its sound and its representation in real words, facilitating understanding of syllable structure.
• 5 tones trainer with acoustic waveform analysis. The application generates visual wave graphs and tone comparisons (mid, low, falling, high, rising). The user records their voice and the system evaluates whether the produced tone matches the target. Visual feedback shows frequency deviations, training both the ear and pronunciation accuracy.
• Spaced repetition flashcards with difficulty ranking. Each flashcard contains the Thai word, romanization, audio, and a contextual image. The algorithm schedules reviews according to the user's recall level. Cards marked as "hard" appear more frequently, while mastered cards are spaced over days or weeks, optimizing long-term retention.
• Audio discrimination quizzes for phonetic pairs. The student hears a word or syllable and must select among four written Thai options. Options include minimal pairs that differ only by one tone or one consonant. This function generates detailed error reports, indicating which phonetic pairs cause the most confusion.
• Script recognition game with stroke order validation. On a touch screen or with a mouse, the user draws a Thai character following the correct stroke sequence. The software analyzes direction, order, and proportions. Scores are awarded for precision and fluency, with correction suggestions shown for improperly executed strokes.
• Progress tracking with XP, streaks, and mastery percentage. Each correct answer adds XP, and completing a daily session extends the streak. The application shows an activity calendar and accuracy statistics per module. The user can visualize their percentage mastery of each vocabulary set and tone competency, motivating consistent practice.
• Numbers and classifiers (lakkhanam) module. Teaches numbers from 0 to 1,000,000 and the mandatory classifiers for objects, people, animals, and shapes. Each exercise presents a quantity and an object, and the student must choose the correct classifier together with the Thai number. The function includes exception tables and reverse translation exercises.
• Phrase lessons for travel and daily conversation. Contains 15 situational categories: restaurant, transportation, hotel, shopping, emergencies, formal and informal greetings. Each phrase is broken into individual words with grammatical annotations. Role-playing exercises simulate dialogues where the user responds to spoken or written questions, receiving immediate corrections.
• True/false test on Thai culture and etiquette. This function presents statements about Thai customs (the wai greeting, head taboo, reverence to the king) and the user decides whether they are true or false. Incorrect answers trigger a detailed explanation. This module integrates linguistic learning with sociocultural competence, essential for avoiding communication errors.
• Timed level examination mode. The student can take exams that combine reading, writing, listening, and tones. Each exam has 20 random questions from the studied modules. Upon completion, a percentile score is generated and errors are listed with direct links to the corresponding lessons for focused review.
• Cross-device synchronization via optional account. Although no registration is required, the user can create an email account or use social login to save all progress, streaks, and scheduled flashcards. Synchronization occurs automatically when reopening the application on another phone, tablet, or computer, maintaining learning continuity.

ThaiLearn was created in 2021 by lead developer John Scott, a software engineer specializing in natural language processing and digital education. The project began as an internal tool to teach Thai to his foreign partner, then expanded into a public application. The core team consists of three developers and two native Thai speakers with linguistics backgrounds. The application is written entirely in the JavaScript programming language, using the React framework for the user interface and Node.js for optional backend services. Local storage is managed with IndexedDB, and script recognition employs custom stroke-tracing algorithms without relying on external libraries. The Windows and Android versions are packaged using Electron and Capacitor respectively, maintaining the same JavaScript core. Since 2022, ThaiLearn incorporates a simple artificial intelligence system to adjust question difficulty based on the student's error history.
