How to use this tool

About this tool

Consensus AI has no published per-file byte limit, but each document is capped at 500,000 words. Scanned PDFs and image-heavy research papers are larger than text-based PDFs and may process more slowly. Compressing before upload reduces file size and improves Ask Paper response quality.
