Sarah M.
Pre-Med Student, UCLA
I used TypeOS for my entire senior thesis. My professor said it was the best-written paper she'd seen all year. Little did she know...
James K.
Management Consultant
As a consultant, I need to produce polished reports fast. TypeOS writes them in minutes and the humanizer makes them sound exactly like me.
Alex R.
Business Major, NYU
I was terrified of Turnitin catching my work. TypeOS scored 0% AI on every single paper I submitted this semester.
Patricia L.
Partner, Corporate Law Firm
Our law firm uses TypeOS to draft initial client memos. It saves our associates 3-4 hours per document.
David C.
English Lit, Stanford
I switched from Quillbot and the difference is night and day. TypeOS actually understands context.
Maria S.
Graduate Researcher
Submitted a 3,000-word paper through GPTZero, Originality.ai, AND Turnitin. All came back as human-written.
Robert T.
Immigration Attorney
The research assistant finds relevant case law faster than Westlaw, and the humanizer ensures my briefs sound authentic.
Priya N.
Psychology Major, UMich
My GPA went from 3.1 to 3.8 this semester. TypeOS helped me write better papers and actually understand my own arguments.
Tom W.
MBA Student, Wharton
After running my humanized text through 5 different detectors and passing every one — I'm a believer.
Frequently Asked Questions
