Lexpad, the AI vocabulary notebookMeet a word. Make it stay.

Lexpad is an AI vocabulary notebook with spaced repetition. Add the words and phrases you meet, let AI complete their cards if you want, and practise them in short daily sessions.

A personal record of the words you meet in your own reading, listening and conversations, each with its meaning and the sentence you found it in, which you review at growing gaps until the words stay. It can be paper, a spreadsheet or an app. See how to make a vocabulary notebook, the free printable template and the digital vocabulary notebook guide.

From what you read and watch: you bring the reading and the vocabulary. Add words yourself, or use Pro’s Words worth keeping to find expressions in your own text and remove anything you already know.

Lexpad uses five Leitner boxes with intervals of today, 1, 3, 7 and 21 days. A correct answer moves a word up one box. A wrong answer returns it to box one. Words in box five count as mastered: they come back after 21 days, then after 45, 90, 180 and 365 days as long as you know them.

Yes. Five Leitner boxes are the default. Each notebook can switch to the Smart schedule, built on FSRS-6 (Beta, free), and back again without losing a box.

Anki and Quizlet are flashcard apps for any subject, with shared decks and sets. Lexpad is a vocabulary notebook for the words you meet yourself: AI writes each card, and the schedule is visible at a glance. See Lexpad vs Anki and Lexpad vs Quizlet, or compare nine Anki alternatives, free and paid.

Lexpad supports 81 languages in any target and meaning-language pair: 6,561 pairs, because the same language can be on both sides for definitions (every language, with its native name and code). Arabic, Hebrew, Persian, Urdu and Pashto are written right to left, each piece of text in its own direction. The app’s screens are in English; this site is also in Türkçe, Español, Português, Deutsch, Français, 日本語 and فارسی.

Yes. Import Kindle highlights from My Clippings.txt or lookups from vocab.db. Import an Anki deck (.apkg) as it is (on the web, in the Android app and in Lexpad for Mac and Windows; the deck is read on Lexpad’s server, so it needs a connection), a CSV or TSV that Anki or Quizlet exported, or paste a Quizlet set’s export text; you see the first cards before they are added. Lexpad also imports its own JSON exports and skips duplicate words. See Kindle to flashcards, Lexpad vs Anki and Anki vs Quizlet, or compare Anki alternatives and free Quizlet alternatives.

Yes, with Pro. It works in the Android app, Chrome, Edge and Safari, and listens in the destination notebook’s language. Review what was heard before adding it; it never saves automatically.

Yes. Lexpad Player is part of the free Lexpad app for Mac and Windows. It plays your own video files (MKV, MP4 and more) with up to three subtitles at once, each styled and timed on its own. R replays the last line, and a click on any word keeps it, with its sentence, in your notebook. Watching needs no account.

Yes. Saved notebooks, practice sessions and progress work from your device, then sync when you reconnect. AI generation, billing, creating a notebook and opening a public shared notebook need an internet connection.

Yes. Add Lexpad from ChatGPT’s Plugins Directory or Claude’s connector directory and approve it on a Lexpad page; other MCP apps use https://api.lexpad.app/mcp. Then ask the assistant to save words, find the words due today or quiz you; answers count as practice. Connecting is free. On Free, ChatGPT and Claude write 10 cards a day; on Pro, chat cards are unlimited (up to 1,000 a day). The assistant never sees your password, and you can disconnect it in Settings, Connected apps.

Yes, in Safari: open app.lexpad.app and add it to your Home Screen (Lexpad on iPhone). It works on iPad too. Android is on Google Play and as a direct APK download, and the Chrome, Edge and Firefox extensions are published.

Yes. Your first notebook, unlimited words in the app (5 a day each from the extension, desktop app, Player), all practice types, both schedules, five games and drills, offline use, sync, export and 5 AI cards a day (200 a month) are free. Optional Pro, 4.99 USD a month or 29.99 USD a year, adds Lex, the AI tutor, for conversational vocabulary practice, Words worth keeping for discovering expressions in your own text, unlimited AI cards one at a time (the same cards as on Free, up to 1,000 a day), Say it and Use it in a sentence, voice input and more notebooks. Every new account gets Pro free for 7 days, no card needed. When it ends, nothing you made is taken away.

Lex is Lexpad’s AI vocabulary tutor, and it comes with Pro. It knows your recently saved words. Chat with it to practise recalling them, compare words that are easy to confuse, and get help using your vocabulary in sentences, stories and writing. Pro gives you 100 messages a day, 2,000 a month. Every new account can try it in the 7-day Pro trial, no card needed. Lex needs an internet connection.

It is a Pro feature in the web app that finds useful words, phrasal verbs and fixed expressions in text you paste. Suggestions start selected; cross out the ones you know. Each saved entry keeps its original sentence. Manual text selection is still available separately.

Your words stay in your notebook and the practice schedule keeps running. Pro continues until the end of the paid period, then the account returns to Free. See the pricing and refund pages for billing details.
