How to Research Across Multiple PDF Documents

To research across multiple PDF documents, begin by identifying what each file is and what you need to compare. Uploading a folder is not enough to define a research task. A small source inventory and a focused question make it easier to spot missing material, conflicting versions and claims that need checking in the original files.

Prepare a source inventory

Give files meaningful names and record their titles, authors or organizations, dates and versions. Remove accidental duplicates from your working set, but keep distinct editions when comparing changes. Note whether a PDF contains selectable text or scanned images. Check extracted text for broken columns, missing tables and incorrect characters.

Ask a question that crosses documents

Frame a comparison around definitions, findings, assumptions or recommendations. Ask the agent to distinguish a statement appearing in one source from a conclusion supported across several sources. A synthesis should identify disagreements and gaps rather than combine every paragraph into a uniform narrative.

  • List the files included in the task.
  • Define the fields you want compared.
  • Separate document evidence from web evidence.
  • Require uncertainty when a source cannot be read fully.

Use files as sources in Humanizily

Attach the supported documents in the Research Agent and explain their role in the brief. Review the proposed outline before the run. If a file cannot be extracted reliably, obtain a readable version or use an appropriate text-extraction step, then inspect the result. Do not assume that every page or table was captured because upload succeeded.

Verify the cross-document synthesis

Open the cited files and locate the passages behind important statements. Where available, check page numbers and section headings; PDF viewer numbering and printed page labels can differ. Record which version supplied the evidence. Before sharing or exporting, inspect the source list and confirm that confidential or restricted files are appropriate for the intended workflow.

Common questions

Does a successful upload mean every page was read?

No. Check extraction quality and any missing or unreadable content.

Should I include duplicate reports?

Use one copy of identical files; keep different editions when the version difference matters.

Can I mix uploaded files and web sources?

Yes, but identify their roles and check the provenance of each cited claim.
