Everything the dictionary gives you
Read deeper, faster.
The full dictionary surface
Word forms, every example, quoted passages with citations, nested subsenses, and clickable synonym & antonym chips — aggregated across the whole entry, not just the first line.
Words that talk to each other
“Form of” senses and synonym chips are live links. Click decades and jump straight to decade — inside the same tooltip, with a back button for your path.
Copy anything, cited
Copy a single definition, a quote with its citation, or the whole entry — formatted and ready to paste into notes, essays, or your own dictionary.
A side panel for long reads
Send any word to the side panel and keep it open while you keep reading. Once it’s open, every word you select lands there — with a search box of your own.
Build your vocabulary
Bookmark words, re-visit your lookups, and study them later. Everything is local — no account, no profile, no tracking.
AI Fallback
