Frequently Asked Questions

  1. Decide what you want to check.

    If you want to compare two complete documents, choose Gap Analysis. If you want to check one specific sentence, paragraph, or section across multiple documents, choose Multi-Document Comparison.

  2. Prepare the information.

    For Gap Analysis, upload the target or new document as the Future State and your existing document as the Current State.

    For Multi-Document Comparison, enter the common section or heading, paste the approved wording that should appear there, and upload the documents you want checked.

  3. Review the appropriate result.

    Gap Analysis identifies missing, changed, and different content across the two complete documents.

    Multi-Document Comparison reports whether the selected wording in each document is aligned, partially matched, or mismatched.

    Gap Analysis example: Compare a new regulatory standard with your current SOP to identify requirements the SOP does not yet address.

    Multi-Document Comparison example: Check whether the approved “Intended Use” paragraph is consistent across a product IFU, clinical summary, and marketing brochure.
