Frequently asked questions

Our support team is here to help you daily via chat, WhatsApp, email, or phone between 9:00 a.m. to 11:00 p.m. CET.

Yes! Our personal statement editors can help you reduce your word count by up to 25%. You can choose to receive this feedback through direct edits or suggestions in comments – just select your choice when you upload your personal statement.

Our APA experts default to APA 7 for editing and formatting. For the Citation Editing Service you are able to choose between APA 6 and 7.

It is not necessary to reserve a time slot for your edit. As soon as your document is ready to be proofread, you can upload it at any time via our website . Based on your chosen deadline, our editor(s) will then proofread your document within 24 hours, 3 days, or 7 days.

If you are unsure about the availability of our services or are planning to upload a very large document (>13,000 words) with a 24 hour deadline, we recommend that you contact us beforehand via chat or email .

Scribbr is following the guidelines announced by the WHO (World Health Organization). As an online platform, all our services remain available, and we will continue to help students as usual.

Can I still place an order? Will my order be completed within the deadline? Yes, you can still place orders and orders will be delivered within the agreed upon deadline. Scribbr is an online platform – our proofreading & editing services are provided by editors working remotely from all over the world. This means Scribbr can guarantee that we will process your order with the same diligence and professionalism as always. The same holds true for our Plagiarism Checker .

Can I still contact customer support? Yes. Our support team is available from 09.00 to 23.00 CET and happy to answer any questions you might have!

Yes, if your document is longer than 20,000 words, you will get a sample of approximately 2,000 words. This sample edit gives you a first impression of the editor’s editing style and a chance to ask questions and give feedback.

How does the sample edit work?

You will receive the sample edit within 12 hours after placing your order. You then have 24 hours to let us know if you’re happy with the sample or if there’s something you would like the editor to do differently.

Read more about how the sample edit works

When you upload a large document (20,000+ words), we will ask your editor to send a sample edit of approximately 2,000 words as soon as possible. This sample edit gives you a first impression of your editor’s editing style and what you can expect from the service. You will receive it within 12 hours after uploading your order.

Why do we provide you with a sample edit?

We always aim to make you 100% happy, and Proofreading & Editing is a complex service. We want to make sure that our editing style meets your expectations before the editor improves your entire document.

Our editors are trained to follow Scribbr’s academic style . However, your preferences might deviate from our conventions. The sample edit gives you the chance to provide feedback – you can let us know if you’re happy with the sample or if there’s something you would like the editor to do differently.

Once your editor has completed your sample edit, you will receive a notification via email. You have 24 hours to reply to this email and provide us with feedback. If we receive your feedback in time, your editor will go the extra mile and adjust the edit according to your input.

What sort of feedback can you give?

Give us feedback that will help your editor meet your requirements. For example:

• “I am completely happy. The editor can continue editing like this.”
• “I forgot to mention that my school has the following rules for gendered pronouns.”
• “The editor changed the spelling of a technical term, but my professor spells it differently. Please keep the original spelling of this term.”

The  Structure  and Clarity Check can only be purchased in conjunction with Proofreading & Editing . Providing feedback on structure and clarity requires extensive knowledge of the text, which the editor acquires while proofreading and editing your text.

However, our Paper Formatting Service,   Citation Editing Service and Plagiarism Checker can be purchased separately.

Yes, Scribbr will proofread the summary in another language as well.

Who will proofread my summary?

If your document contains a summary in a different language, we will send this part to another editor who is a native speaker of that language. The editor will check your summary, applying our standard Proofreading & Editing service.

If you ordered any additional services, such as the Structure Check or Clarity Check, the editor will not apply them to your summary. This is because the summary is a translation of your abstract – you already receive Structure and Clarity feedback on the text in the original language. Therefore, when proofreading your summary, the editor will focus on making sure your language and style is correct.

How does it work?

We will create a new assignment within your order and send you a confirmation email. This also means that you will receive a separate email/SMS notification from us when the editor has finished proofreading your summary. Once your summary is proofread, you can download it via your Scribbr account and read the editor’s feedback.

Yes, we can provide a certificate of proofreading.

As soon as the editor delivers the edit, you can email us at [email protected] to request a certificate.

Please indicate the following in your email:

• Your order number
• Your full name
• The title of your work

We will create a PDF certificate and email it to you as soon as possible.

Scribbr specializes in editing study-related documents . We proofread:

• PhD dissertations
• Research proposals
• Personal statements
• Admission essays
• Motivation letters
• Reflection papers
• Journal articles
• Capstone projects

Yes, when you accept all changes and delete all comments your document is ready to be handed in.

How to accept all changes:

• Word for Mac 2011

How to remove all comments:

When you’ve finished this, others will no longer be able to see the changes made by the editor.

• Read your last version one last time to make sure everything is the way you want it.
• Save your document as a .pdf file to come across more professional and to ensure the format of your document doesn’t change.

Yes, in the order process you can indicate your preference for American, British, or Australian English .

If you don’t choose one, your editor will follow the style of English you currently use. If your editor has any questions about this, we will contact you.

Yes, you can upload your thesis in sections.

We try our best to ensure that the same editor checks all the different sections of your thesis. When you upload a new file, our system recognizes you as a returning customer, and we immediately contact the editor who helped you before.

However, we cannot guarantee that the same editor will be available. Your chances are higher if

• You send us your text as soon as possible and
• You can be flexible about the deadline.

Please note that the shorter your deadline is, the bigger the risk that your previous editor is not available.

If your previous editor isn’t available, then we will inform you immediately and look for another qualified editor. Fear not! Every Scribbr editor follows the  Scribbr Improvement Model  and will deliver high-quality work.

However, every editor has a slightly different editing style, so you may notice small inconsistencies in editing choices. As with every proofreading order, be sure to carefully review your editor’s changes and suggestions as you finalize your text to ensure that everything is as you want it.

The fastest turnaround time is 12 hours.

You can upload your document at any time and choose between three deadlines:

At Scribbr, we promise to make every customer 100% happy with the service we offer. Our philosophy: Your complaint is always justified – no denial, no doubts.

Our customer support team is here to find the solution that helps you the most, whether that’s a free new edit or a refund for the service.

Every Scribbr order comes with our award-winning Proofreading & Editing service , which combines two important stages of the revision process.

For a more comprehensive edit, you can add a Structure Check or Clarity Check to your order. With these building blocks, you can customize the kind of feedback you receive.

You might be familiar with a different set of editing terms. To help you understand what you can expect at Scribbr, we created this table:

View an example

Scribbr not only specializes in proofreading and editing texts in English , but also in several other languages . This way, we help out students from all over the world.

As a global academic writing proofreading service, we work with professional editors  – all native speakers – who edit in the following languages :

This way, you can also have your academic writing proofread and edited in your second language!

Please note that we do not offer Finnish proofreading, but students can still upload English papers on scribbr.fi .

Yes, regardless of the deadline you choose, our editors can proofread your document during weekends and holidays.

Example: If you select the 12-hour service on Saturday, you will receive your edited document back within 12 hours on Sunday.

The footnotes are not automatically included in the word count.

If you want the language errors in your footnotes to be corrected by the editor, you can indicate this in step 3 of the upload process . The words in the footnotes are then automatically added to the total word count.

Need help with your references?

• If you use the APA reference style, you can use our free APA Citation Generator or the articles about APA in our Knowledge Base.
• If you’d like us to check your references for consistency, you can use our Citation Editing Service .

To keep our prices competitive, we do not offer a free trial edit. However, if your document is longer than 30,000 words, we are happy to provide you with a sample edit of 2,000 words to ensure you are satisfied with the editor’s editing style.

Rest assured, our customers are very satisfied with our proofreading services. We’re proud that they have rated us with an excellent 4.6 on Trustpilot. In the unlikely event that you have a less positive experience, we’ll solve that with our 100% happiness guarantee !

After your thesis has been edited , you will receive an email with a link to download the edited document.

The editor has made changes to your document using ‘ Track Changes ’ in Word.  This means that you only have to accept or ignore the changes that are made in the text one by one.

It is also possible to accept all changes at once. However, we strongly advise you not to do so for the following reasons:

• You can learn much by looking at what mistakes you have made.
• The editors do not only change the text, they also place comments when sentences or sometimes even entire paragraphs are unclear. We therefore advise you to read through these comments and take into account your editor’s tips and suggestions.
• Because of the many changes, sometimes there may be double spaces, double periods, or other minor mistakes in a sentence. Checking the changes one by one, you can easily detect these minor errors.

We have written a manual in which we explain step by step how ‘Track Changes’ works.

Check out an example

Our editors are very experienced and will do their utmost to correct all errors in your thesis .

However, with our current rates, an editor can only check your thesis once. This may cause an editor to overlook an error. We can therefore not guarantee that your thesis is 100% error free after you have had your thesis edited.

The editor uses ‘Track Changes’ in Word when editing your thesis.

Don’t know how this works? Then read the following guide  in which we explain step by step how ‘Track Changes’ works.

No, we do not provide you with a clean copy. You will always receive a file edited with tracked changes .

We do this for two main reasons:

• In most papers, there are sentences that the editor cannot edit without additional information from the author. In these cases, your editor will provide guidance but leave you to implement the feedback. If we were to simply accept the changes for you, then these issues would be left unaddressed.
• We believe students should be accountable for their work. Our editors can correct language errors and coach you to be a better writer. However, the end product belongs to you and should reflect your ideas and decisions.

All Scribbr editors are language experts with interests in different subject areas.

You can indicate your field of study when you upload your document . We’ll make sure that the editor who proofreads your work is familiar with your discipline and its specialist vocabulary.

These are the fields of study you can choose from, and examples of the main subjects in each field:

• Business and Management: Business Administration, Hotel Management, Accountancy, Marketing
• Economics: Business Economics, Econometrics, Finance
• IT and Engineering: ICT, Computer Science, Artificial Intelligence, Applied Mathematics, Civil Engineering, Industrial Design, Electrical Engineering
• Natural and Life Sciences: Biomedical Sciences, Biology, Chemistry
• Geography, Agriculture and Environment: Ecology, Earth Sciences, Environmental Studies, Urban Planning
• Health and Medical Sciences: Medicine, Obstetrics, Pharmacy, Nutrition, Dentistry
• Arts and Humanities: Philosophy, History, Literature, Cultural Studies, Theology
• Law and Policy: Law, Political Science, Public Policy, Human Rights
• Social and Behavioral Sciences: Psychology, Sociology, Anthropology, Communication Sciences

Editors don’t have to be experts in the content of your paper, but they do know how to present it in the best way possible! Our goal is to improve your writing and give you feedback on the readability, structure, logic, and clarity of your text. We know from experience that the most effective editors are specialists in language and academic writing.

We’ve carefully selected and trained all of our editors to proofread theses and other academic documents. Once they’re qualified, we continue to carefully monitor their work to make sure we always deliver the highest quality .

Frequently asked questions

The Scribbr Grammar Checker is a tailor-made AI-powered tool that can correct basic language, grammar, style, and spelling errors. We run it so that our editors are free to focus on what they do best: making sure that your paper is free of more nuanced mistakes and providing you with helpful feedback and writing tips.

The Scribbr Grammar Checker is a pro at correcting basic mistakes – and a human editor will still be carefully reviewing your full text – so you can rest assured that your paper is in very good hands!

When you receive back a document that has been reviewed by the Scribbr Grammar Checker, you’ll see two sets of tracked changes in it: one set from the grammar checker and one set from your editor. That way, you can easily tell who made what changes in your paper.

Not sure how tracked changes work in Word or how to review your edited file? Read our handy guide to learn more.

We tested ten of the most popular free grammar checkers to see how many errors they could fix in our sample text and deducted points for any new errors introduced. We also evaluated the tools’ usability.

When compared all the other grammar checkers we tested for this comparison and Scribbr performed exceptionally well. It was successful in detecting and correcting 19 of the 20 errors. See the full review here .

If our grammar checker flags an error that is not actually an error, you have several options:

1. Ignore the error: Most grammar checkers allow users to skip or ignore suggestions they do not agree with or find irrelevant. If you are confident that the flagged “error” is not an issue, you can bypass the suggestion and move on to the next one.

2. Review the context: Take a moment to thoroughly review the context surrounding the flagged error. Sometimes, the initial correct usage might still create confusion or ambiguity within the specific context, and reconsidering the phrasing could improve overall clarity.

Yes, this grammar checker covers the following mistakes:

1. Grammar: Correction of grammatical errors such as subject-verb agreement, tense usage, and sentence structure

2. Spelling: identification and correction of spelling errors, including typos and commonly confused words.

3. Punctuation: Detection and rectification of punctuation errors, including incorrect use of commas, periods, colons, and other punctuation.

4. Word choice errors: Catch words that sound similar but aren’t, like their vs. they’re and your vs. you’re.
