    Upload or compare PDFs

    Start with one addendum, or pair an old bid document with its revised issue.

  2. 02

    Review the drafted checklist

    Read required actions, bid risks, scope changes, and affected document references.

  3. 03

    Check source snippets

    Verify each important finding against the issued PDF before updating the bid.

Early beta

Test with documents you can safely share.

AddendaLens is best tested with public, old, redacted, or non-sensitive addenda. The goal is blunt estimator feedback on what helps and what still needs checking by hand.

Not official bid review.

Always verify against issued bid documents.
