ThaiJam

ThaiJam takes you from your first Thai letters to words, everyday sentences and speaking out loud. Follow a learning path, start with a song you love, or practise what needs work today. [FROM THE ALPHABET TO EVERYDAY THAI] The alphabet path covers consonants, vowels, tones and reading, with stroke-order demos, visual memory aids and tracing practice. The conversation path teaches words, sentences and patterns through situations such as greetings, ordering food and getting around. Explore 2,000+ common Thai words, everyday sentences and step-by-step sentence-pattern lessons. Cards bring together Thai script, romanisation, translations, examples and audio. You can also choose male or female speech for your practice. [GO BEYOND RECOGNISING THE ANSWER] Practise with matching, listening, fill-in-the-blank, word-order and three Thai typing drills: copy it, type from the meaning and type what you hear. A daily sentence and pattern give you something manageable to practise each day. Create your own word and sentence cards and organise them into decks. Spaced repetition schedules reviews according to how well you know each card, using your practice results to bring back what you need to remember. [PRACTISE SPEAKING] Guided sentence speaking takes you from listening to repeating, then saying a complete sentence without looking at the answer. Pronunciation checks on word and sentence cards show accuracy, fluency and completeness, with a history of your attempts. In AI Conversations, practise introductions, ordering food and drinks, and asking for directions with Jammy. Listen to replies, use hints when needed, then review feedback and useful phrases afterwards. Available scenarios and detailed feedback vary by plan. [LEARN FROM SONGS AND WORDS YOU FIND] Import your own songs and lyrics, play and sing along line by line, look up words in the lyrics and add favourite lines to your reviews. You can also connect Apple Music or Spotify. Playback through those services is subject to their own subscription requirements; imported audio does not need either subscription. Search the dictionary by Thai, romanisation or meaning. When you want more help, use AI for word explanations, translations, sentence breakdowns, extra examples or lyric analysis. [LET JAMMY GUIDE YOUR NEXT STEP] Jammy Daily Coach suggests practice based on your goals, level, available time and interests. Insights into weak spots show what needs attention and lead you back to a relevant card, speaking exercise or pronunciation check. [COLLECT JAMMY CARD] Open packs with coins earned through learning and collect consonant cards. Learning achievements and visits to select landmarks in Thailand can unlock more cards. Follow your collection and the Leaderboard, turn duplicate cards into fragments, and choose a card you own as your avatar. [CHOOSE THE AI AND MEMBERSHIP OPTIONS YOU NEED] ThaiJam Plus and Max add the full Daily Coach path, deeper weakness and conversation analysis, larger daily AI allowances and a Member Card that upgrades with your membership history. Included member usage is used first; you confirm before spending AI credits. Core lessons, cards and reviews remain available. [KEEP YOUR PROGRESS] Track your learning history, streak and achievements. Connect an Apple or Google account to continue your progress and personal content on another device. [LEARN WITH JAMMY ON YOUR HOME SCREEN] The iOS Home Screen widget puts a Thai word, your due reviews, and your learning streak within reach. Move to the next word with a tap. The medium widget also shows todayβs progress and lets you reveal the meaning after making a guess. Go at your own pace: remember a little more today, then say one more sentence aloud.
