Collocations · corrections · saved phrases

Make your Spanish sound natural.

Type a phrase. Get fast feedback on awkward collocations, plus a clean corrected version you can copy and reuse.

How it works

  1. 1 Send a phrase.
  2. 2 The backend checks collocations and streams suggestions in real time.
  3. 3 Save the best phrases to review later (stored locally on your device).
