Four levels of the grammar check
Our proofreaders check your text on every linguistic level, more precisely than any AI.
Spelling
Typos, hyphenated and compound spellings, capitalisation and the current spelling rules (Duden for German).
Grammar
The AI checks sentence structure, case, tense and agreement, so everything beyond pure spelling.
Punctuation
Punctuation with commas, hyphens and apostrophes, checked against the applicable rules.
Style & expression
Repeated words, clumsy phrasing and unnecessary filler words disappear.
Why a professional grammar check instead of AI?
AI tools such as ChatGPT, DeepL Write or the Duden online check have become strong in recent years, but they still make plenty of mistakes. In our tool comparison even the best AI systems found only 80 to 85 % of the errors. For academic texts such as your bachelor's or master's thesis, that is not enough.
Our experts at corrected.eu keep the error rate to a maximum of 3 %. Beyond pure spelling, they analyse levels that AI often overlooks: style, expression, consistency and semantic coherence.
How the grammar check works
1. Upload your file. Upload your text as .docx, .pdf, .odt or .rtf. You can order straight away, and no registration is needed.
2. Choose your delivery time. Choose Standard (5 days), Express 48 h or Express 24 h. We also process your file at weekends and on public holidays.
3. A proofreader takes over. A specialist proofreader with at least 7 years of experience checks your text manually: it is not a pure AI correction.
4. Receive your corrected text. You receive a Word file with track changes switched on, so you can accept or reject each correction individually.
Which texts is the grammar check suitable for?
We proofread texts in English and German: from bachelor's theses, term papers and dissertations to job applications, novels and professional documents. Both UK and US English are possible.
What does a professional grammar check cost?
Our professional grammar check costs from €1.90 per standard page (1,800 characters including spaces). You will find more information on how pages are counted on our page on standard pages. The final prices depend on the delivery time (5 days / 48 h / 24 h) and the depth of correction you want: you will find all prices on our price page.

Frequently asked questions about the grammar check
How does a professional grammar check differ from an AI?
Automatic AI checkers miss 15 to 20 % of errors and often make things worse. Experienced proofreaders keep the error rate under 3 % and also analyse style, expression and semantics. You can see the detailed comparison in our grammar check test.
What does a grammar check cost per page?
Costs start at €1.90 per standard page (1,800 characters). Express 48 h costs €2.90 and Express 24 h costs €4.90. You will find the full price list and packages in the shop.
How quickly do I get my text back?
Choose between Standard (5 days), Express 48 h or Express 24 h. The delivery time starts immediately after the order, around the clock, including weekends and public holidays.
Which file formats are accepted?
For proofreading, you upload a PDF or DOCX of up to 100 MB. Export a LaTeX file beforehand as a compiled PDF. With DOCX, you get the text back with track changes, so you can accept or reject each correction individually.
Is the grammar check suitable for bachelor's and master's theses?
Yes. Our experts specialise in academic writing and have proofread bachelor's, master's and diploma theses as well as dissertations, term papers and seminar papers. You will find more information on the bachelor's thesis page.
Do I need an account to order?
No. You order straight after the upload, with no registration or login. Your data is stored on servers in Germany in line with the GDPR.
