1983 is a vocabulary map. Every word in the catalogue is placed in two dimensions: intensity (from mild to extreme) and nuance (the axis that distinguishes near-synonyms). Open a cluster — say, "Shades of Anger" — and you see the entire neighborhood at a glance: irked vs incandescent vs apoplectic, all mapped, all clickable. The catalogue is curated, not crawled: 1,863 words across 208 clusters and 15 superclusters, each definition hand-written, each example pulled from public-domain literature or anchored in mythology. No filler, no near-duplicates. What's inside: THE SHELF — Browse the full map by supercluster, then drill into clusters of 4 to 30 words. Toggle the nuance axis to re-arrange the cluster from a different angle. THE DRILL — Three quiz modes: definition (which word means X), nuance (which option has the right shade), and intensity (rank by strength). Questions adapt to what you've missed. THE RECORD — A 90-day heatmap of practice, a list of your most-missed words, and a mastery archive that fills in as you progress. Master a cluster and earn a printed patch. THE DAILY — A Word of the Day widget for your home screen, refreshed every morning from the catalogue. Tap it to jump straight to the card. 7-day free trial, then $5.99/month auto-renewing subscription. Cancel anytime in Settings. Apple Sign In, Google Sign In, or email signup. Built for writers, GRE/SAT candidates, ESL speakers ready for the upper register, and anyone who got tired of looking words up only to forget them the next day.
