Why the combo beats separate tools
One Pass, Not Two
Running grammar check then humanizer separately means the humanizer can introduce new grammar errors. Our combo fixes grammar and humanizes simultaneously — no reintroduced mistakes.
Context-Aware Fixes
Our grammar engine understands the humanization context. It doesn't just fix errors — it fixes them in a way that supports the humanization transformation, not fights it.
Change Transparency
See exactly what was fixed and what was humanized. Grammar fixes are highlighted in blue, humanization edits in orange. Full transparency, no black-box processing.
Save Time & Money
Instead of paying for a grammar checker AND a humanizer, get both in one tool. One subscription, one pass, one result — clean, correct, and human.
Frequently asked questions
How is this different from running a grammar checker and humanizer separately?
When you run a grammar checker first and then a humanizer, the humanizer can introduce new grammar errors during its rewriting process. Our combo engine fixes grammar and humanizes in a single pass, ensuring no new errors are introduced. It's also faster and cheaper than using two separate tools.
What types of grammar errors does it fix?
We detect and fix 50+ grammar error types including spelling, punctuation, subject-verb agreement, tense consistency, article usage (a/an/the), preposition errors, comma splices, run-on sentences, dangling modifiers, capitalization, and more. The strictness level controls how aggressive the fixes are.
Will the humanized text bypass AI detectors?
Yes. Our output is tested against Turnitin, GPTZero, Originality.ai, Copyleaks, Winston AI, and 10+ other detectors. We consistently achieve under 5% AI score. The combo tool applies the same humanization engine as our standalone humanizer, with the added benefit of grammar correction.
Does it preserve my original meaning?
Absolutely. Our engine preserves semantic meaning — facts, arguments, and intent remain identical. Grammar fixes correct surface-level errors, and humanization changes word patterns and sentence structure without altering your core message.
What are the different modes for?
Academic mode preserves scholarly tone for essays and research papers. Casual mode adds conversational informality for blogs and social media. Professional mode maintains business-appropriate tone for emails and reports. SEO mode optimizes for readability while preserving keywords for web content.
Is my text stored or shared?
No. Your text is processed in real-time and immediately discarded. We have zero data retention — nothing is stored, logged, or used for training. Your content is never shared with third parties.
