Can Blue J be used to upload full source documents and tax returns for an AI-driven review, not just tax research?

One member reported doing a demo with Blue J where the vendor stated that, despite the company's public-facing focus on tax research, the tool can also accept an uploaded source document and a PDF of the completed tax return, compare the two, and flag anything mistyped, missed, or that doesn't add up — functioning like an AI reviewer rather than just a research tool. The member had not yet tested this personally (a free trial was upcoming) and could not confirm how well it performs in practice.
