01Where it runs

Server-local text comparison between two PDFs

02File lifetime

A temporary per-request workspace is cleaned when processing ends.

03Known limits

Different text extraction order or column structure can appear as differences even when pages look visually similar. Scanned PDFs require OCR before meaningful text comparison.

04Verify after download

Use the report to locate changes, then inspect the original passages manually when the difference is sensitive or legally important.

Workspace

Ready

Sample files contain demonstration content only. They are included so you can test the workflow before using your own data.

INFINITY INTELLIGENCE

A copilot that understands this tool.

Ask what a setting means, whether this is the right tool, how to recover from an error, or what to do with the result next. Infinity receives safe context from this page — not the file contents automatically.

PRACTICAL CONTEXT

What this tool is good at — and where to be careful.

BEST FOR

When this tool makes sense

Reviewing text changes between two PDF versions, such as a contract, report, or policy, when textual differences matter most.

HOW IT WORKS

What the engine actually does

Text is extracted from both PDFs and compared line by line with a unified diff. The result is a TXT report showing additions and removals. This is not a pixel-level visual comparison.

LIMITS

What it does not promise

Different text extraction order or column structure can appear as differences even when pages look visually similar. Scanned PDFs require OCR before meaningful text comparison.

CHECK

A 20-second quality check

Use the report to locate changes, then inspect the original passages manually when the difference is sensitive or legally important.

Frequently asked questions

Does it compare visual layout?

No. The current comparison is text-based rather than pixel- or position-based.

What if both files match?

The report explicitly says no text differences were found instead of returning an empty file.

No cloud file history

Public conversions are designed around temporary request workspaces, not permanent file storage.
