Lexpad – Vocabulary Notebook & FlashcardsOAuth via extension

app.lexpad

Lexpad is a vocabulary notebook and flashcard app with spaced repetition (Leitner boxes) for learning words in 81 languages, including English, Spanish, French, German, Arabic, Turkish and Persian. Connect it to ChatGPT, Claude or any MCP client, and your assistant works with the words you collected yourself: • Save words and phrases you ask for, with meanings, example sentences and a level (A1–C2). • Find anything: browse and filter your whole notebook by due, new, struggling, starred or mastered words, level, topic or date added. • Practise: get quizzed on today's due words. Every answer counts as real review, moves the word through the Leitner boxes and keeps your streak. • Edit: fix spellings, change or reorder meanings, star or retire words. Deleting needs its own permission, and the assistant asks first. Lexpad never invents vocabulary: it only works with the words you add, by hand, from a text, or imported from Anki or a Kindle. Sign-in is OAuth on a Lexpad page; your password is never shared, and you can disconnect at any time. Works alongside the Lexpad web app and Android app. Guide and example prompts: https://lexpad.app/features/assistants
