About this tool

Repeating the same word weakens writing. This finder taps the free Datamuse API — the engine behind the popular OneLook tools — to return synonyms and antonyms ranked by real usage strength, not just dictionary order. It is ideal for tightening an essay, varying marketing copy, or teaching vocabulary. Only the single word you type is sent to the API; nothing else leaves your browser.

FAQ

Where does the data come from?
The free Datamuse API, built on large English corpora — the same source used by OneLook's reverse dictionary.
Why are results ranked?
By corpus frequency and relatedness — the top results are the strongest substitutes in real writing.
Does it work for phrases?
Best with single words; for phrases try the key noun or verb.
Are these exact synonyms?
Ranked 'related and replaceable in many contexts' — always sanity-check tone and register.
Is there a limit?
The free API is generous; only the word you type is sent per lookup.
Can I use results commercially?
Yes — word facts aren't copyrightable; the API is free to query.
