Online Tools to Improve Your English Writing

As a blogger and a person who works in marketing, I deal with a lot of English text content. Though English is my native language, it is not my specialization, although that is quickly changing the more I read and write. Here are some online tools I’ve found very useful for anyone wanting to improve their writing.


Grammarly can do many things including alerting you to typos, incorrect grammar, wordy phrases, inconsistent spelling, and more. It does this by underlining words in red or blue so you can quickly jump to words or phrases that could be improved. For example, in the screenshot below, the word “effect” is misspelled. On the right, there is an explanation of the typo and a link to learn more. Clicking on the box will fix the typo.

If you double-click on a word, you can get synonyms.

Grammarly has a great handbook in their blog that explains many grammar topics concisely and with good examples.

Note that Grammarly is not perfect and does not replace human review. is the first sentence search engine that helps you write better English by giving you contextualized examples taken from reliable sources.

As you can see in the screenshot above, Ludwig can do many things including

  • Find your sentence in the best contexts
  • Translate in English in the smartest way
  • Get definitions, synonyms and examples
  • Compare the frequency of two sentences
  • Discover the missing word
  • Paraphrase your sentence
  • Compare the frequency of words
  • Order a group of words


WordTune helps you rewrite words and sentences. They can be shortened, expanded, and made to sound more casual or formal.

If you highlight a word and click on the WordTune icon, you can get synonyms.
