About

Feel stuck reading real content in French or another language?

You understand the main idea.
But unknown words keep pulling you out of the text.
And you can’t tell which words you actually know and which you don’t.

WordByWord helps you take control of your vocabulary — on any website.

Turn any page, YouTube video, or PDF into a visual vocabulary map.

🔦 SPOTLIGHT MODE – SEE YOUR VOCABULARY
Stop guessing your level.

• Instantly highlight unknown words on any webpage
• Color-coded by learning status (new → learning → known)
• See how much of the page you truly understand
• Update word status directly on the page
• Watch your vocabulary grow over time

Now you don’t just read a language.
You see exactly where you stand.
