You've been building a vocabulary list for years.
Here's the rest of the app.

Every word you ever looked up on your Kindle® e-reader — with its sentence, its book, and its date — ready to study in two minutes. Parsed entirely in your browser. Never uploaded.


The quiet record

Your e-reader kept the list. It never went anywhere. Until now.

Every Kindle® e-reader with Vocabulary Builder turned on keeps a quiet record: every word you've looked up, the sentence you met it in, the book, and the date. It's all in one file on the device.

Plug in.
Connect your e-reader to your computer with a USB cable. It appears as a drive.
Find the file.
Open the device and find system/vocabulary/vocab.db. (On most devices the system folder is right at the top level.)
Drag it in.
Drop the file onto the import page. Vocabularium reads it right there in your browser and shows you everything it found — words grouped by book, each with its original sentence. Pick what to keep, and they flow straight into your study queue.
Why the sentence matters. A standard flashcard says "perspicacious: having keen insight." Yours says the sentence from the novel you were reading in bed last March, with the title underneath. You don't just recall the definition — you remember the scene. That's not a gimmick; it's how memory encoding works.
The privacy part, plainly: your file is parsed entirely in your browser. Nothing is uploaded. We never see your reading data — and we couldn't if we wanted to.
Also works with My Clippings.txt
Highlight a sentence with a word worth keeping, and import that too — the same drag, the same browser-only parsing. Highlighters welcome.
Two minutes from now

Meet your words again.

The list is already on your device. The cable is in the drawer. The rest takes one drag.
