The Stakes Are High

Attorneys have been sanctioned for citing AI-generated cases that don't exist.

Since 2023, lawyers have faced sanctions and public embarrassment for submitting briefs with fabricated case citations. Whether from AI tools or simple research errors, bad citations can derail cases and careers.

Three steps to certainty

Upload, verify, and proceed with confidence.

1

Upload Your Brief

Upload a PDF, Word document, or paste text directly. We support briefs, motions, and memos up to 50 pages.

2

AI Verification

We extract every citation, verify it exists in legal databases, check if it's been overruled, and confirm the case actually says what you claim it says.

3

Get Your Report

Receive a detailed report with verified citations, flagged issues, and suggested corrections. Export as PDF or CSV.

4 Layers of Verification

What we actually verify

Most tools just check if a case exists. We go further with comprehensive verification that protects you from Rule 11 sanctions.

Proposition Verification

Core

We extract what you claim each citation supports, then analyze the actual case holding to verify it matches. Flags mismatches before they become sanctions.

Example catch:

Brief claims: “Standing established per Smith v. Jones”
Actual holding: Smith v. Jones is about contract formation, not standing

Quote Accuracy

Critical

Direct quotes must appear verbatim in the source. We use fuzzy matching to catch alterations, omissions, and fabrications—even accounting for OCR errors.

Example catch:

Brief quotes: “conduct was malicious”
Source says: “conduct was not malicious”

Case Treatment

Essential

We check if your cited cases are still good law. Flags overruled, abrogated, or superseded precedent before you rely on it.

Example catch:

Citing: Roe v. Wade (1973) for constitutional right
Status: Overruled by Dobbs v. Jackson (2022)

Statute Verification

Complete

Validates U.S.C., C.F.R., and California code citations. Catches wrong section numbers and repealed statutes with links to official sources.

Example catch:

Brief cites: 42 U.S.C. § 1983.5
Problem: Section 1983.5 does not exist

Built for legal professionals

Every feature designed with attorneys in mind.

CourtListener Integration

Direct access to 10+ million cases. We verify against the authoritative legal database, not web search results.

Fast Results

Most briefs are verified in under 5 minutes. Get your report before your deadline, not after.

Risk Assessment

Citations flagged by severity: verified, needs review, not found, incorrect, or overruled. Focus on what matters most.

Secure & Confidential

Your documents are encrypted at rest and in transit. Auto-deleted after 24 hours. Attorney-client privilege protected.

Multiple Formats

Upload PDFs, Word docs, or paste text directly. Export reports as PDF, CSV, or view in-browser.

AI Artifact Detection

Scans for AI-generated patterns, placeholder text, and prompt leaks. Catches what others miss.

Simple, transparent pricing

Pay per document. No subscriptions, no commitments.
