I am aware of individuals, for whom English is not their first language, who utilize ChatGPT to ensure their writing appears more fluent.
I actually much preferred your original comment, but if I were going to rework it I'd try to eliminate the comma-delimited parenthetical. Simply dropping the commas would be an improvement, at which point the only other change I'd make would be to replace "reads fluent" with "reads fluently".
What ChatGPT did instead was double down on that comma clause to make it even more distracting, and keep "fluent" as is while lengthening the rest of the clause to make that usage grammatically correct. It kept the wrong anchor points from your original formulation and ended up changing more than it needed to for a worse result.
