What it does

A reverse dictionary: type a definition — 'the feeling of being watched' — and it returns candidate words, alongside a thesaurus, wildcard pattern matching for crosswords, and rhymes. It queries a large set of dictionaries at once instead of one publisher's. The interface has been plain for twenty years and is all the better for it.

Best for

  • The word on the tip of your tongue
  • Crossword and puzzle patterns

Where it stops

Results are ranked statistically, so a vague description returns a long list you have to read through yourself.
