Our verdict on Chonvy

Chonvy is a free, web-based AI research workspace for students and researchers who need to examine research papers and other PDF documents. Users can upload documents, explore extracted sections, figures, and tables, then ask questions about methods, results, and limitations. Answers are linked to exact passages or page regions, giving readers a way to check the response against the source material. Chonvy can also be used without creating an account.

Its strongest capability is visual, passage-linked research analysis. A user can select a figure or region as chat context, browse the document’s extracted structure, and ask targeted questions about specific evidence. The Library extends this approach to multiple uploaded papers, supporting questions across a small research collection rather than limiting analysis to one document at a time. That combination makes Chonvy a focused option for reading and comparing academic PDFs through a web interface.

Chonvy is a good fit for students and researchers who want free, browser-based assistance with paper comprehension and source checking. The 10 MB upload limit may constrain larger PDF documents, and usage limits may apply. It is also limited to the web, with no described integrations or export workflow. Choose Chonvy when passage links, figure context, table browsing, and multi-paper questions matter most; choose another tool if you need broader platform support, document automation, or a workflow built around integrations and exports.

I've used Chonvy myself and this is my honest opinion — nobody paid or asked me to write it.
