Why should you use a free essay checker?

The simple answer? Good grammar is necessary, but it's not easy. You've already done countless hours of research to write the essay. You don't want to spend countless hours correcting it too.

You'll get a better grade

Good grammar, or its absence, can determine if you get a good grade or a failing one. Impress your lecturer not just with how grammatically sound your writing is but how clear it is and how it flows.

You'll save time

Essay writing can be a long and tedious process. ProWritingAid's essay checker saves you the hassle by acting as the first line of defense against pesky grammar issues.

You'll become a better writer

Essay writing is a particular skill and one that becomes better with practice. Every time you run your essay through ProWritingAid's essay corrector, you get to see what your common mistakes are and how to fix them.

Good Writing = Good Grades

It's already hard to know what to write in an essay. Don't let grammar mistakes hinder your writing and prevent you from getting a good grade. ProWritingAid's essay checker will help you write your best essay yet. Since the checker is powered by AI, using it means that grammar errors don't stand a chance. Give your professors something to look forward to reading with clear, concise, and professional writing.

How does ProWritingAid's essay checker work?

Your goal in essay writing is to convey your message as best as possible. ProWritingAid's essay checker is the first step toward doing this.

Get rid of spelling errors

ProWritingAid's essay checker will show you what it thinks are spelling errors and present you with possible corrections. If a word is flagged and it's actually spelled correctly, you can always choose to ignore the suggestion.

Fix grammar errors

Professors aren't fans of poor grammar because it interrupts your message and makes your essay hard to understand. ProWritingAid will run a grammar check on your paper to ensure that your message is precise and is being communicated the way you intended.

Get rid of punctuation mistakes

A missing period or comma here and there may not seem that serious, but you'll lose marks for punctuation errors. Run ProWritingAid's essay checker to use the correct punctuation marks every time and elevate your writing.

Improve readability

Make sure that in the grand scheme, your language is not too complicated. The essay checker's built-in Readability report will show if your essay is easy or hard to read. It specifically zones in on paragraphs that might be difficult to read so you can review them.

What else can the essay checker do?

The editing tool analyzes your text and highlights a variety of key writing issues, such as overused words, incohesive sentence structures, punctuation issues, repeated phrases, and inconsistencies.

You don't need to drown your essay in words just to meet the word count. ProWritingAid's essay checker will help to make your words more effective. You'll get to construct your arguments and make sure that every word you use builds toward a meaningful conclusion.

Transition words help organize your ideas by showing the relationship between them. The essay checker has a built-in Transition report that highlights and shows the percentage of transitions used in your essay. Use the results to add transitions where necessary.

An engaging essay has sentences of varying lengths. Don't bore your professor with long, rambling sentences. The essay checker will show you where you need to break long sentences into shorter sentences or add more sentence length variation.

Generally, in scholarly writing, with its emphasis on precision and clarity, the active voice is preferred. However, the passive voice is acceptable in some instances. When you run your essay through ProWritingAid's essay checker, you get feedback on whether you're using the passive or active voice to convey your idea.

There are specific academic power verbs, like appraise , investigate , debunk , support , etc., that can add more impact to your argument by giving a more positive and confident tone. The essay checker will check your writing for power verbs and notify you if you have less than three throughout your essay.

It's easy to get attached to certain phrases and use them as crutches in your essays, but this gives the impression of boring and repetitive writing. The essay checker will highlight your repeats and suggest contextually relevant alternatives.

Gain access to in-house blog reports on citations, how to write a thesis statement, how to write a conclusion, and more. Venture into a world of resources specific to your academic needs.

• Descriptive
• Textual analysis
