DOCUMENT REVIEW SUPPORT

Selected Risk & Anomaly Checks

Rule-based checks look for selected missing fields in supported contract and invoice types, conflicting detected dates or contract/payment amounts, and arithmetic mismatches when a subtotal, tax, and total are all detected. Review each result in the original PDF.

Examples below are from the bundled demo PDF and are for demonstration only.

CONSISTENCY REVIEW

Consistency Checks

Flag multiple detected values for selected date and amount fields, or a subtotal-plus-tax mismatch when all figures are found.

Rule-based checks cover selected dates, amounts, and supported arithmetic. They do not assess legal meaning.
warningReview flagged items

DocTrace is an automated review aid, not legal advice. Extraction and rule-based checks can miss or misread content. Confidence scores are heuristic estimates, not calibrated probabilities. Verify results in the original PDF and consult a qualified lawyer for legal decisions.

forum DOCUMENT TEXT SEARCH CHAT

Ask about the analyzed document.

DocTrace searches the uploaded PDF text for matching passages and returns a source page when it finds relevant text. It does not interpret legal effect.
