ThesisAI turns the papers you give it into a referenced first draft of 8 to 80 pages in one run. Papero takes the other route: you write the paper, with an outline, sentence suggestions, rewrites, citations from real scholarly records and six review checks. Both are for students and researchers; they suit different ways of working.
Updated October 2026 with prices and features from both sites.

ThesisAI and Papero solve different problems. ThesisAI generates a long referenced draft for you to rework. Papero helps you write the paper yourself, step by step, with citations from real records and a review before you submit, and has a free plan.
Yes, if you want to write the paper yourself with AI help. Papero gives you an outline, sentence suggestions, rewrites, OpenAlex paper search and six review checks in one editor.
Papero Plus is $12 a month or $96 a year. ThesisAI lists Basic at $12/month and Pro at $16/month, each for 4 documents a month, when we checked in October 2026.

No. Papero can draft a section from its prompt, but it is built to help you write: sentence suggestions, rewrites of text you select, citations and checks. The argument stays yours.
Papero supports APA 7, MLA 9, Chicago author-date, Harvard and IEEE. ThesisAI lists Alphabetic, Numeric, APA, IEEE, Harvard, Oxford, Chicago Notes and Chicago Author-Date.
Papero never uses your documents to train AI models. ThesisAI says it never uses customer content to train models.
