When it comes to writing essays with AI, most people turn to ChatGPT without a second thought. It’s fast, flexible, and generally great at spitting out structured, readable essays in seconds.

But there's another player in the space now — Undetectable AI's Essay Writer. It doesn’t try to be the most advanced thinker in the room. It tries to sound human enough to fly under the radar.

So the real question isn’t just “which one writes better essays?”
It’s also: “which one sounds more like a person wrote it?”

Let’s break down what each tool does — and why the answer might not be as obvious as it seems.

What is ChatGPT?

Unless you've been living under a rock with no Wi-Fi, you’ve probably heard of ChatGPT. Built by OpenAI, it's a conversational AI that can write everything from Shakespearean sonnets to five-paragraph essays on the Cold War — all in under a minute.

It’s widely used by students, marketers, and just about everyone who needs clean, structured text on demand.

The upside: it's smart, versatile, and gives you decent writing with little effort.

The downside: if you’re not careful, it sounds like AI wrote it — especially to detection tools, or professors who’ve read 100 other papers that all sound the same.

What is Undetectable AI’s Essay Writer?

Undetectable AI isn’t trying to win a Pulitzer. It’s trying to make sure your essay doesn’t get flagged.

Their Essay Writer is built around one goal: make the writing sound like a real person — filler words, imperfect transitions, and all. It’s intentionally less polished than ChatGPT by design. But that’s the point. It feels more human.

It lets you choose a tone, tweak the structure, and control how “AI-ish” your final product sounds. The tool leans hard into believability over brilliance. It’s for people who don’t want a robot-perfect essay but something that could’ve come from a slightly tired college student on a Tuesday night.

ChatGPT vs. Undetectable AI: Writing Quality

Aaron Sorkin's scriptwriting style is a unique blend of intellect, wit, and fast-paced dialogue. His scripts are characterized by complex, layered storytelling and a keen sense of social commentary. Sorkin's writing often explores the intricacies of human relationships, delving into the motivations and emotions of his characters. His dialogue is renowned for its cleverness and rapid-fire delivery, with characters frequently engaging in lengthy, insightful conversations. One of the defining features of Sorkin's style is his use of "walk-and-talk" scenes, where characters discuss important topics while moving through a setting. This technique creates a sense of energy and momentum, drawing the viewer into the world of the story. Sorkin's scripts also frequently incorporate satire and social commentary, tackling issues such as politics, media, and technology. His writing is often described as "intelligent" and "sophisticated," reflecting his own interests in history, philosophy, and culture. Sorkin's characters are often flawed, yet relatable, and his writing brings out their nuances and contradictions. He has a particular talent for crafting strong, intelligent female characters, as seen in shows like "The West Wing" and "Newsroom." Throughout his career, Sorkin has demonstrated a commitment to exploring complex themes and ideas, and his scripts continue to engage and challenge audiences. With his distinctive writing style, Sorkin has established himself as one of the most respected and influential screenwriters of his generation, leaving an indelible mark on the world of film and television. His unique voice and perspective have captivated audiences, and his scripts remain a testament to the power of intelligent, thought-provoking storytelling.	Aaron Sorkin’s scriptwriting style is instantly recognizable—rapid-fire dialogue, intellectual banter, and morally charged storylines that unfold with rhythmic precision. Often described as “Sorkinesque,” his writing blends theatrical pacing with razor-sharp wit, giving characters an almost musical cadence in their speech. Whether in The West Wing, The Social Network, or The Newsroom, Sorkin’s scenes tend to move quickly, not because of action, but because of talk—dense, articulate, and often idealistic talk. One of his most famous trademarks is the “walk and talk” technique, where characters deliver long stretches of dialogue while moving through hallways or across busy environments. This creates both physical momentum and a sense of urgency, turning what could be static exposition into a dynamic exchange. His characters are often passionate professionals—lawyers, journalists, politicians—who speak with conviction and fluency, often engaging in debates that expose deeper philosophical or ethical tensions. Critics sometimes argue that his characters all sound the same—too clever, too rehearsed—but fans embrace the stylization as part of his charm. Sorkin doesn’t strive for realism; he aims for an elevated version of it—where language reveals not just information, but identity, purpose, and the pursuit of truth.

There’s no contest here — ChatGPT is the better writer.

It structures arguments better, uses stronger transitions, and builds flow like a real essay writer would. You can ask it to use rhetorical techniques, quote sources, and mimic formal writing styles. It can even format in APA or MLA if you nudge it right.

Undetectable AI, meanwhile, plays it safe. It doesn’t overreach. The result is often blander — but also less likely to raise red flags for being “too perfect.”

If you’re being graded on writing alone, ChatGPT wins. But there’s another layer to this.
