The solicitation controls. Use any comparison tool as a review aid, then confirm requirements, deadlines, attachments, and acknowledgment instructions in the official solicitation package.
Start with the correct document pair
Use the prior version you actually reviewed and the latest revised solicitation or amendment package you intend to respond to. A clean comparison depends on comparing the right two source documents.
Review the changes that can affect submission work
- Response, quote, bid, or proposal due dates and times.
- Quantities, line items, delivery schedules, specifications, and attachments.
- Clauses, forms, submission instructions, and amendment-acknowledgment language.
Use source-backed output, not a summary alone
Gold Standard Analysis shows the detected before/after text with source-page references so you can return to the supplied PDFs. It does not decide whether a change is legally material or whether your response is compliant or responsive.
What Gold Standard Analysis compares
The current product compares two machine-readable PDFs. It does not perform OCR. Source PDF bytes and full extracted text remain browser-local; paid access is bound to SHA-256 fingerprints of the selected pair.
