What Proofreading & Writing Aid tools can do for you
3 tools listed
The proofreading and writing aid tools help with the revising stage, when you reread what you have written. They flag the spots that tend to bother readers: wordy phrasing, double negatives, inconsistent spelling or capitalization, repeated words and sentence openings, and overly long sentences.
If you want to see readability in numbers, you can check average sentence length, comma density, the balance of short and long sentences and readability scores. Related tools estimate reading time and speaking time, track your writing pace, compare two versions of a text and generate citations in common styles such as APA, MLA and IEEE.
The results are mechanical suggestions, not verdicts, so keep your own judgment for the final call. Your text is processed in your browser and is never uploaded.
Handy when you need to
- ✓ Revise a blog post, essay or report before publishing
- ✓ Spot repetitive sentence openings, wordy phrases and passive constructions
- ✓ Estimate reading time or speech length
- ✓ See exactly what changed between two drafts
Pro tip
Start with consistency, wordiness and repetition checks, which usually make the biggest difference. If you only need counts, the counters in Text Formatting & Conversion are quicker.
Proofreading & Writing Aid: frequently asked questions
- Q. Should I fix everything a checker flags?
- A. No. These tools look for patterns, so they can flag phrasing you chose on purpose. Use the results as a guide and change only what fits your intent.
- Q. Can I estimate how long a text takes to read aloud?
- A. Yes. Paste your text into the reading time tool and adjust the speed to get an estimate for silent reading or speaking.
