A clean draft still hides small errors: subject-verb agreement, missing commas, repeated words, and spelling slips. Plagiarisma’s free grammar and spell checker uses AI to scan your text and flag issues you can fix before you submit or publish. Paste a passage or upload a document and review each suggestion. It is a proofreading aid for students, writers, and teams — not a substitute for your own final read.

How to Use Grammar Suggestions Without Flattening Your Voice

A checker finds likely errors. It does not know your tone, field terms, or intended emphasis. Accept fixes that are clearly wrong, and keep wording that is correct for your context.

1. Fix clear errors first

Start with spelling, doubled words, and agreement mistakes. Those are the changes that almost always help.

• Correct misspellings and missing letters.

• Fix subject-verb agreement and tense shifts that break the sentence.

• Leave technical terms and proper names if the tool flags them by mistake.

2. Do not accept every style suggestion

Some tools mark long sentences or informal phrasing as errors. A long sentence can be the right one if it is clear.

• Keep a deliberate short sentence for emphasis.

• Reject a rewrite that changes your claim.

• Read the paragraph aloud after you apply a batch of fixes.

3. Check meaning after you edit

A grammar fix can nudge a sentence into saying something else. Compare the original and the corrected line before you move on.

4. Pair the check with originality and AI review when the text matters

Clean grammar does not make a passage original. For essays and articles, run the plagiarism checker after you proofread, and use the AI detector if you need a second look at machine-like sections.

The goal is a cleaner draft that still sounds like you, not a text rewritten into a generic style.
