Between AI detection paranoia and the battle to make ChatGPT sound much less… effectively, ChatGPT-ish, instruments like Undetectable AI and Rewritify have carved out fairly the area of interest for themselves. They promise to take robotic textual content and infuse it with these little human quirks all of us have in our writing β however do they really ship?
As somebody who’s been down this rabbit gap, I had the very same query. That is why I’ve put each platforms head-to-head throughout readability, detection exams, and pricing. The outcomes? Let’s simply say that whereas each instruments do what they declare, one in every of them persistently outperforms in ways in which made me do a double-take.
However which one? Letβs discover out.
What are Undetectable AI and Rewritify?
Most college students have gone by false accusations of utilizing AI for his or her schoolwork. AI humanizers are made to resolve that.
Undetectable AI and Rewritify are AI humanizers and bypassers which flip one thing that reads like AI into one thing extra human-sounding. That is doable by eradicating widespread AI markers (repetitions, overused AI phrases, and hallucinations) and including a number of intentional errors to humanize your content material.

Undetectable AI vs. Rewritify: Readability
Elm timber, as soon as widespread, are deciduous timber recognized for his or her vase-like form and serrated leaves. They thrived in temperate areas, however Dutch elm illness decimated populations. Some species, just like the American elm, are recovering by disease-resistant cultivars. Elms present shade and habitat, enjoying a significant position in ecosystems. |
Elms, as soon as widespread, are deciduous timber with a vase form and serrated leaves. They grew in cooler areas, however Dutch elm illness killed them. Some species, like American elm, are coming again with illness resistant cultivars. Elms shade and stay in, have an amazing ecological perform. |
Deciduous timber, elm timber, as soon as ubiquitous, are characterised byβtheir vase-like form and serrated leaves. Theyβflourished in temperate areas, however Dutch elm illness exterminated numbers. Some species are coming again because of new disease-resistant cultivars, suchβbecause the American elm. Elms are shade timber that supplyβhabitat and are an essential a part of ecosystems. |
The very first thing that jumps out is tone and readability. Undetectable AI leans easy and direct, virtually stripped to the bone, whereas Rewritify is extra overrated β generally awkwardly so. I imply β “elm timber, as soon as ubiquitous, are characterised by their vase-like form” sounds prefer it got here from a thesaurus-fueled fever dream.Β
Rewritify takes liberties with phrasing (“exterminated numbers”? Actually?) that muddy that means as a substitute of clarifying it. Grammar-wise, itβs principally intact, however the sentence development feels compelled and unnatural.
Undetectable AI, alternatively, isnβt flawless β it drops articles (“American elm” as a substitute of the American elm) and has the clunky line “Elms shade and stay in,” which reads like somebody hit “shuffle” on a grammar app. Nonetheless, it is extra devoted to the unique and feels simpler to digest. The core message stays intact, even when the polish is lacking.Β
Between the 2, Undetectable AI is tough across the edges, however Rewritify overreaches and finally ends up sounding robotic. If weβre going for closeness to the supply and readability, Undetectable AI takes the win β arms down.

Undetectable AI vs. Rewritify: Pricing
Let’s discuss pricing as a result of β let’s be actual β your pockets issues.Β
Undetectable AIβs pricing construction is fairly simple: $5/mo for his or her yearly plan with a 50% low cost or $19/mo for his or her month-to-month possibility. Each plans include a phrase restrict β 10,000 and 20,000 phrases respectively β with the power to scale as much as 380,000 phrases if wanted.

On the flip facet, Rewritify affords three tiers: Primary at $14/mo for five,000 phrases, Final at $24/mo for 50,000 phrases, and an Limitless possibility at a whopping $49/mo. The worth proposition is crystal clear right here β Rewritifyβs Final plan provides you 5x the phrases in comparison with their Primary plan for lower than double the worth.Β

However here is the place it will get attention-grabbing: Undetectable AIβs yearly plan at $5/mo for 10,000 phrases completely demolishes Rewritifyβs Primary plan which fees almost triple for half the phrases.
So, Which Ought to You Decide?
I broke this down into three classes: readability, bypassing AI detection, and pricing β unsurprisingly, Undetectable AI gained all three.
Itβs simply miles higher than the closest competitors. The one factor Undetectable AI lacks is ideal readability, and itβll be laborious to not suggest it to everybody.
As for Rewritify, itβs actually good, however I simply donβt assume itβs a worthwhile expense. It doesnβt do something that Undetectable AI canβt, and itβs much less versatile in pricing. To not point out that theyβre a bit stingy with regards to free trials (80 phrases most per account in comparison with Undetectable AIβs 200 phrases + each day spins totally free phrases), which makes their device extra inaccessible.
One factor earlier than you go: at all times use these instruments for good. With that in thoughts, I extremely suggest checking this text out. Good luck!
