Lexpad από Reza Pirighadim

Lexpad is a personal vocabulary notebook with spaced repetition. This extension is the fastest way to fill it: while you read, select a word and a small button appears.

What it does
- Click the button, or right-click a selection and choose "Add to Lexpad".
- A card shows the meaning, a short definition and an example while the word is added, so a word you did not know is explained on the spot. Meanings are written in the language of your notebook.
- The sentence you met the word in is saved as its first example, and the page as a private note, so you remember where it came from.
- Choose which notebook new words go to from the toolbar popup, and switch the selection button off if you prefer the right-click menu.
- Enter adds, Escape closes. Light and dark themes follow your system.

Your account
The extension never asks for your password. Click "Connect to Lexpad", allow it in the Lexpad web app, and it gets a session of its own. It appears in Lexpad under Settings → Signed-in devices, where you can sign it out at any time.

What it sends
Only when you add a word: the selected text, the sentence around it, and the page's address and title go to Lexpad's own servers (api.lexpad.app) and nowhere else. Nothing is sent while you browse.

Lexpad is free. A Lexpad account is required: https://app.lexpad.app
