Research workflow

Summaries that stay connected to the document

A useful PDF summary needs more than compression. Rixx keeps the file in the research session so you can ask where a claim appears, request a risk table, compare sections, extract data, and keep moving toward an output.

  • Summarize the whole PDF
  • Ask section-level questions
  • Turn findings into report sections

Use web research when the PDF is not enough

Many documents need outside context. Rixx can combine file-grounded answers with cited web research, helping users check whether a report is current, whether a claim is widely supported, or whether a missing source changes the conclusion.

From document to deliverable

Use Rixx to create a study guide, diligence memo, legal evidence outline, market note, executive summary, or downloadable report from the same PDF conversation.

How it works

  1. Upload the PDF: Attach the document and let Rixx process the source context.
  2. Ask for the right summary: Choose a quick brief, detailed extraction, claim check, or comparison.
  3. Create the output: Export notes, build a chart, generate a report, or save an insight.
