Compare two documents

Checking revisions is a routine task: a contract after a counterparty's edits, a policy after approval, an estimate after recalculation. Upload the original and the new revision: the service extracts the text, compares it and shows what changed. Formatting is ignored — the textual edits are what matter. Files are not kept in storage after processing.

Questions and answers

Which document formats are supported?

DOCX, PDF with a text layer, XLSX, XLS, and plain text formats: TXT, MD, CSV, JSON, XML, YAML, HTML, CSS, JS, PY, SQL and others.

Is document formatting compared?

No, only the text. Fonts, indents and colours do not affect the result.

Can I compare a scanned PDF?

Not yet: a text layer is required. A scan without OCR is rejected with a clear message instead of showing an empty result.

What about the old .doc format?

Re-save the file as .docx — the legacy binary format is not supported.

Are uploaded documents stored?

No. The file is processed and discarded; only a fingerprint of the pair remains in the database.
