Pro Tips for Better Results
Get the most out of the AI Grammar Checker with these expert tips.
Use “Correct Only” when wording must stay the same
For compliance, legal, or stakeholder-approved copy, minimal changes reduce risk while still fixing grammar and punctuation mistakes.
Check one section at a time for cleaner edits
For long articles, proofread in sections (intro, one heading at a time). This improves coherence and reduces the chance of unintended phrasing changes.
Keep SEO terms consistent
If your content targets specific keywords, keep those terms unchanged. After polishing, quickly scan headings and the first paragraph to ensure the primary keyword still appears naturally.
Watch for meaning-critical words
Double-check numbers, dates, negations (not/never), and product names after edits—small changes can alter meaning in marketing and technical writing.
Polish after you finalize structure
Run a grammar check after headings and the overall structure are final. You’ll avoid re-editing text you later move or remove.

How to Use an AI Grammar Checker Without Losing Your Voice
Most people think grammar checking is just about fixing typos. It is not. The real win is this: you keep your meaning, your style, and your intent… while removing the little errors that make readers hesitate.
A good AI grammar checker should help with:
- grammar and agreement issues (subject verb, tense consistency)
- punctuation that changes meaning (commas, apostrophes, run-ons)
- spelling that slips through when you write fast
- awkward phrasing that sounds fine in your head, but weird out loud
- clarity, so the reader does not have to reread the same sentence twice
Paste your text, pick a mode, and treat the result like a smart second draft. Not a replacement for you.
What This Grammar Checker Actually Fixes (And What It Does Not)
It helps most with real world writing: emails, landing pages, essays, blog posts, product descriptions, and anything you publish publicly.
It usually catches:
Grammar mistakes that hurt credibility
Things like “Their is” instead of “There is”, mismatched verb tenses, missing articles, and messy sentence boundaries.
Punctuation that changes the message
A comma in the wrong place can flip the meaning, or at least make it harder to scan. The tool cleans that up.
Clarity and flow issues
This is where “Clarity + Flow” mode shines. It removes clutter, trims repetition, and makes sentences feel more natural.
What it does not do:
- it is not a plagiarism checker
- it is not a fact checker
- it will not magically make weak ideas strong, it just helps your writing come across clean
Which Mode Should You Choose?
If you are not sure, start with Clarity + Flow. It gives the best overall improvement for most writing.
- Correct Only (Minimal Changes): best for legal, compliance, stakeholder approved copy, or anything where wording must stay nearly identical.
- Clarity + Flow: best for blogs, web pages, essays, and general writing where readability matters.
- Formal: best for academic writing, client emails, proposals, and serious business communication.
- SEO Polish: best when you want a light cleanup but need to keep keywords and headings intact for on page SEO.
Grammar Checking for SEO: Why It Matters More Than People Admit
SEO is not just keywords. If your page feels sloppy, people leave. That bounce, that lack of engagement, it adds up.
Clean grammar helps with:
- trust (especially on money pages like services, pricing, and product pages)
- readability and scanning (shorter, clearer sentences keep people moving)
- conversions (fewer “wait what?” moments)
- content refreshes (old pages often rank better after a cleanup)
If you write content regularly, a grammar checker becomes part of your publishing process, like spellcheck, but smarter. If you are already using AI for drafting and rewriting, pairing it with a proper editing pass inside an AI writing platform like Junia AI makes the whole workflow feel smoother.
A Simple Proofreading Workflow That Works (Even When You Are Busy)
- Write fast first. Get the ideas down.
- Run one section at a time. Intros, one heading, one block of copy. Cleaner results.
- Scan for meaning critical stuff. Numbers, dates, “not”, brand names, product terms.
- Read it out loud once. You will catch the last weird line that still sounds robotic.
- Do a final pass for intent. Make sure it still sounds like you.
Common Grammar Mistakes This Tool Helps You Avoid
A quick list, because these show up constantly:
- there/their/they’re confusion
- your/you’re
- “could of” instead of “could have”
- missing apostrophes in contractions
- inconsistent capitalization in headings and sentences
- run-on sentences and comma splices
- switching tense mid paragraph
- duplicate words (the the) that your brain skips over
Mini Example: Before and After (What a Real Fix Looks Like)
When grammar tools are good, they do not rewrite everything. They fix what is broken, then gently smooth the rest.
Before:

After:
