By skyforbes Short answer: not impressed.
Here’s my honest take as a student actually using it for real coursework:
1. It oversimplifies academic writing
I tried using TwainGPT to rewrite a 450-word paragraph from my literature analysis class.
The original was about symbolism in Toni Morrison’s Beloved.
TwainGPT turned it into something that sounded like a 8th-grade book report:
removed all nuance
cut transitions
dumbed down vocabulary
changed “cultural trauma” into “sad experiences from the past” (??)
My professor would’ve roasted me alive if I submitted that.
2. It introduces weird “creative” sentences
TwainGPT tries to “sound original,” but sometimes it makes things worse.
In my history essay, I had a line about economic policies during the Great Depression. TwainGPT rewrote it as:
“People were financially drowning and the government threw them a soggy life-jacket.”
I’m sorry but WHAT 😂
There’s no universe where I can submit that.
3. AI detectors flagged the outputs
I checked a couple of rewritten paragraphs on Content at Scale and Sapling.
TwainGPT outputs were flagged as 60–80% AI-written, even though the tool claims to “humanize” text.
For discussion posts, maybe it’s fine — but definitely not for essays.
4. It sometimes changed the meaning
For my marketing class, we had to describe the difference between market segmentation and targeting. TwainGPT blended them into one idea and rewrote it like they were the same concept.
That would be an automatic zero on the rubric.
My comparison
I tested a few tools side-by-side because I was trying to find something reliable.
For me, Grubby AI did much better overall — especially for academic writing.
Some examples:
It rewrote my organizational behavior reflection without removing the academic tone.
It kept citations intact (TwainGPT deleted them completely).
It improved the flow instead of breaking it.
AI detectors showed much lower “AI likelihood” scores, which made me feel a lot safer.
One time I used it for a 600-word criminology summary, and it managed to rewrite it without losing key details or messing with definition terms — something TwainGPT kept doing.
Not saying Grubby is perfect, but compared to TwainGPT, it felt way more stable and usable for college work.
Final thought
TwainGPT might be okay for casual rewriting or shorter paragraphs.
But for academic work, structured assignments, or anything that needs to avoid sounding robotic, I personally wouldn’t rely on it.
If anyone else tried it, curious what your experience was.
