Tips & recommendations
Pro tips to get the most out of this tool.
Always do a pre-submission pass
Duplicated sentences often sneak in during editing. A 10-second scan catches them before they reach your tutor or client.
Add variety to repeated phrases
When a phrase repeats, swap synonyms or restructure — it reads better and looks more original.
Keep clichés out of formal writing
Phrases like “think outside the box” weaken academic and professional tone. Use precise language instead.
This is a first pass, not a verdict
