One answer across
the whole file set
| Source | Evidence |
|---|---|
| Industry Report A, p. 47 | Estimates $2.1B, excluding government demand |
| Industry Report B, p. 112 | Estimates $3.8B, including government demand |
| Analyst Appendix, p. 206 | Government demand accounts for approximately $1.6B |
The report preserves each source, explains the disagreement and makes the evidence inspectable.
Go beyond
summarizing one PDF
A basic AI PDF summarizer is useful when one short document contains the answer.
- The answer is spread across dozens of files
- Different documents use different terminology
- A spreadsheet changes the interpretation of a report
- Two sources make incompatible claims
- The critical evidence appears on an unexpected page
Continua analyzes the complete uploaded set rather than treating each file as an isolated chat.
Six outputs from one investigation
Multi-document Summaries
Create one coherent report across PDFs, Word documents and spreadsheets.
Topic-specific Analysis
Identify everything the complete file set says about a question, risk, event or entity.
Cross-document Comparisons
Compare versions, sources, claims, dates, definitions and numerical assumptions.
Contradiction Detection
Surface where files disagree instead of smoothing conflicting evidence into one confident answer.
Cited Report Generation
Link every material finding to its source document and page.
Inspectable Evidence
Review cited, conflicted, duplicated and unused findings rather than trusting an opaque answer.
Ask the entire document set one question
Analyze all uploaded files and summarize the evidence concerning Topic A. Explain where the sources agree, where they conflict and why their conclusions differ. Cite every material finding to the exact source document and page.
Continua returns a structured investigation report — not merely a short paragraph about one file.
Investigations Continua is built for
Industry and market research
Synthesize findings across reports and explain why market estimates or forecasts differ.
Financial-document analysis
Compare statements, schedules, exports and narrative disclosures.
Contract and policy analysis
Trace changed terms and conflicting requirements across versions and attachments.
Incident investigation
Reconstruct a timeline from reports, correspondence, tickets and supporting records.
Claims and case-file review
Identify relevant events, gaps and conflicting accounts across the evidence set.
From file pile to cited report
Upload the complete set
Add PDFs, DOCX files, spreadsheets and CSV exports relevant to the question.
Define the investigation
Use your own instructions or select a ready-made research template.
Analyze every uploaded page
Continua examines the full corpus and reasons across documents and formats.
Review the cited report
Inspect findings, conflicts and underlying evidence.
Export the result
Export the report for colleagues, clients or further professional analysis.
Built for the work
ordinary PDF summarizers struggle with
| Basic PDF summarizer | Continua |
|---|---|
| Usually optimized for one file | Designed for complete file sets |
| Produces a quick recap | Produces a structured investigation |
| May answer from selected passages | Analyzes every uploaded page |
| Treats conflicting sources as noise | Explicitly identifies contradictions |
| Limited source transparency | Page-level lineage for material findings |
| Best for simple reading | Built for work that must be checked |
Continua can still analyze a single file. Its advantage becomes most important when the document is long or the answer depends on relationships across multiple files.
Narrative and structured files together
- DOCX
- XLSX
- CSV
Analyze narrative documents and structured exports together in one task.
Zero document retention
- Uploaded files are deleted after the task
- Files are not used to train AI models
- Reports are exportable
- Findings remain linked to supporting evidence
Frequently asked questions
Can Continua summarize multiple PDFs together?
Yes. Multiple PDFs and other supported files can be analyzed as one investigation.
Can it handle long documents?
Yes. Continua is designed for large private document sets and long-context analysis.
How is this different from chat with PDF?
Chat-with-PDF tools are usually optimized for questions about one file. Continua is designed to investigate complete document sets, identify conflicts and produce a cited report.
Does every finding have a citation?
Material findings link to their source document and page.
Can it analyze spreadsheets with PDFs?
Yes. PDF, DOCX, XLSX and CSV files can be analyzed together.
