Thesify is an AI academic writing assistant built on feedback: it says it never writes for you, and its Reviewer gives a structured pre-submission review with section scores, gaps in argument and evidence, and similar works. Papero helps you write the paper too, with an outline, one-sentence suggestions, citations from real scholarly records and six review checks.
Updated October 2026 with prices and features from both sites.
