A local model can rewrite a sentence, but a grammar app is usually more precise.

  • Sensitive text never leaves the PC
  • Works for a paragraph with no account
  • Offline, including on a plane

Where it falls short

  • Small models miss subtle grammar
  • They sometimes change your meaning

Our take

For grammar, a dedicated checker is the better tool. Stay local when the text itself is confidential.

Choose local if…

  • The text is private
  • You only need a light rewrite

Choose cloud if…

  • You want the mistake marked
  • You live in Word or a browser
