WordSense
Your brain on words.
Build vocabulary the way reading does — through context, not memorization. Each round drops you into a real passage with one word highlighted, and you figure out what it means from the clues around it. Adaptive difficulty, four levels, and a word bank that tracks what you've earned.
Open This Tool
This runs as a live, interactive experience inside Claude, not a page on this site. Click below and it opens directly.

Free to use. You'll need a Claude account (the free tier works) to run it, and it uses your own account's usage, not mine.
What It Does
- Fresh passages every round, written live by Claude, no static question bank
- No flashcards, no definitions handed to you — the meaning has to be deduced from context, the way real reading works
- Four difficulty levels, from direct clues to figurative use, that adapt to your streak
- Progress, word bank, and milestone badges saved automatically to your browser
How It Works
- Click "Open in Claude" above and sign in with a free Claude account if you're not already
- Choose "Allow" the first time it asks to use Claude — that's how it writes each passage on your own account
- Read each passage and choose what the highlighted word means from the clues around it
- Get three right in a row and the difficulty goes up; miss two and it steps back to reinforce the basics
