Vocabulary Practice & Builder · InterSub

An English vocabulary practice bot for people who keep saving words from films, series and websites and never come back to them. It turns those words into daily vocab practice with an AI language tutor, three to five minutes a day. 📥 Your word sources • Your intersub.cc dictionary, linked with a QR code. Words saved from a film, a series or a website keep the line you met them in. • A CSV or XLSX file, or a list you paste into the chat, one word per line. • Thirteen ready topics, such as travel, food and work, plus a core set of about 4,000 common English words, if you'd rather learn vocab by subject. You tick the ones you already know, and the rest become your new words to learn. ✍️ How a session goes 1️⃣ Reviews come first, as in a vocab trainer: you recall what a word means, name it from its translation, or fill it into a gap in a sentence. Miss one, and it comes back a few cards later in the same session. 2️⃣ Then new words. If you know one, a single tap moves on. 3️⃣ If it's new to you, you get a card: meanings in your language, from the general sense to the one in your sentence, where and how it's used, examples, and the line where you met it, with a translation. 4️⃣ The card also has a transcription and a button to hear the word. Some cards carry a short checked fact or a note on the word's origin. 5️⃣ You make up two or three sentences with it, by text or voice. If you get stuck, ask for a hint first and ready examples after that. Practicing vocabulary in your own sentences is what makes it stick. 6️⃣ The tutor replies in three parts: your version, what to correct, and the corrected version. You type the corrected sentence yourself. 🔁 Spaced repetition Every answer goes into an FSRS schedule, so each word returns at a growing interval, close to the moment you would forget it. If a word was easy, one tap sends it further out. Learning vocabulary this way takes a few minutes a day, not long sessions. ⏰ Reminders on your schedule Set your time zone and the times you want to practice your vocabulary. Each reminder offers a short session; you can put it off for an hour or skip it, and skipped sessions don't pile up. If you stop halfway, the next reminder that day takes you back to where you left off. 💬 Ask our AI language teacher anything Ask about a word, a phrase or grammar at any time, by text or voice. Our AI English tutor replies in the language you picked for explanations; in a session it then picks up where you were. 🌐 Languages ▸ You can learn words in English, German, Spanish, French, Russian, Polish, Czech, Chinese, Japanese and Korean. The ready topics are English only. ▸ Explanations come in any of these languages, plus Ukrainian and Bulgarian. ▸ Menus are in English, Russian, Ukrainian and Spanish. ❓ FAQ ❔ How is it different from a word list? A list only stores words. Here you learn English with AI: a vocab builder brings them back until you can use them, so vocabulary study takes five minutes a day instead of rereading. ❔ Do I need InterSub? No. Upload a file, paste a list or start vocab learning with the ready topics. ❔ Is it free? Yes, the bot is free. Automatic import from your intersub.cc dictionary needs a paid InterSub plan; files, lists and topics work without one. ❔ Can I stop reminders or delete my data? /stop turns reminders off, and /delete removes your account and data. ❔ How do I send feedback? Type /feedback or pick it in the menu, then write or dictate what you like, what gets in the way and what's missing. It is not a course for beginners and not exam prep. It is a vocabulary builder and a vocabulary trainer: learn new words, then practice vocabulary words until you can use them, not just recognize them.
