Gatsbi is an AI research assistant: it generates research ideas with originality scores, drafts full papers from your research notes with in-text citations, and runs systematic reviews and meta-analyses. Papero takes the other route: you write the paper, with an outline, sentence suggestions, citations from real scholarly records and six review checks.
Updated October 2026 with prices and features from both sites.
Prices and features change often. We checked these on Gatsbi's own website on 20 October 2026; check its site before you decide, and tell us at contact@papero.ai if something here is out of date.

Gatsbi and Papero solve different problems. Gatsbi generates ideas, drafts and systematic reviews for you to rework. Papero helps you write the paper yourself, step by step, with citations from real records, a review before you submit and a clear promise about training.
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, VAT included. Gatsbi listed Pro at $19.99/Month or $159.99/Year when we checked in October 2026, and its homepage lists a free plan with limited usage.
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 never uses your documents to train AI models. We did not find a statement about training on Gatsbi's pages in October 2026; check its privacy page before you upload unpublished work.
Yes. If you start from a generated draft, rewrite it in Papero and check its sources and claims with the Review panel.
Choose Papero to write the paper yourself with checks before you submit. Choose Gatsbi if a generated draft or a systematic review workflow is what you want.
