AI-generated writing has come a great distance β and now the instruments that make it sound much less like AI are catching up too.
Weβre not simply speaking about grammar checkers or tone polishers. Weβre speaking about full-on βhumanizersβ β instruments that take AI-written content material and make it really feel like an individual really sat down and wrote it.
Undetectable AI has been targeted on this area from the start. Grammarly? Not a lot. However with its new AI humanizer, Grammarly is moving into that lane. So we figured itβs price asking: which one really does a greater job at making AI writing really feel human when paired with ChatGPT?
Letβs break it down.
What’s Undetectable AI?
Undetectable AI isnβt constructed to make your writing sound prettier β itβs right here to make your AI-generated content material sound undetectable.
Meaning it doesnβt simply rewrite for tone or grammar. It targets the precise markers that set off AI detection instruments: overused phrases, overly structured transitions, and that telltale βmachine voiceβ most massive language fashions canβt shake.Β
Itβs principally utilized by college students, writers, and entrepreneurs who need the velocity of AI with out getting flagged for it. And it does that job properly. Particularly with options just like the Writing Type Replicator, which helps you to prepare the system to sound such as you, not only a generic human voice.
So in case your objective is to cross AI detection β or at the very least fly below the radar β this instrument was actually designed for that.
What’s Grammarly?
Grammarly used to simply catch your typos. However in the present day, itβs attempting to be your full-on writing accomplice. And to be honest, itβs come a great distance.
At presentβs Grammarly can counsel rewrites, change tone, and even generate content material from scratch. The brand new AI humanizer is its reply to the rising want for much less robotic-sounding content material β the sort of output that doesnβt instantly scream βChatGPT wrote this.β
However right hereβs the factor: Grammarly isnβt actually attempting to cover the AI-ness of your writing. Itβs extra about smoothing it out. The humanizer leans into pleasant, easy-to-read polish β much less for evasion, extra for engagement.
That makes it nice for emails, blogs, and social posts. But when your objective is to keep away from detection? Grammarlyβs not the instrument for that.

Two completely different instruments. Two completely different targets. It simply is dependent upon what youβre aiming for.
