📋 Why you need an audit trail
Every citation you verify with a signed-in account saves a timestamped record including:
- What you checked
- When you checked it
- What GhostCite found
- Which court record was searched
If opposing counsel challenges your source, you have PDF proof you verified before filing.
This is not a feature. It's malpractice protection.
Why free, and why unrestricted?
We built GhostCite as a free public utility because probabilistic AI hallucinations threaten the integrity of filings and firm reputations. You shouldn’t have to create a web account or rent another platform to verify your citations before a filing deadline.
But manual copy-and-paste at the finish line is a symptom of a fractured workflow. If your associates use consumer AI tools to draft, checking for errors by hand at the end relies on hope, not architecture. If they forget to check, your firm carries the liability.
True risk mitigation means moving verification up the pipeline, integrating deterministic checks natively into your firm’s private environment.
Move GhostCite inside your private network
Don’t manage another external web login. Integrate our verification engine directly into your practice workflows.
What workflow integration delivers:
- Automated verification: GhostCite silently monitors your internal AI drafting environments, catching hallucinations before a draft is even finalized.
- Ingress redaction (Presidio): strips client identifiers and PII before text ever leaves your perimeter, so data leaks are blocked at the door.
- Policy-as-code (Preflight): programmatically locks down system exports if a citation check fails, forcing active associate supervision before a partner signs.
- Total sovereignty: runs inside a private cloud tenant your firm owns and controls outright. No third-party vendor can audit your history or hold your matter logs hostage.

About GhostCite
GhostCite verifies citations and quoted passages against CourtListener, a free and open public database of US court opinions. It is named for Rule 26, the federal disclosure obligation attorneys already carry. This tool confirms that the building blocks of your brief exist in the public record. You can paste sections or full drafts, GhostCite is designed for real-world briefs, not just toy examples. Always perform a final citator check (Shepard’s, KeyCite) for doctrinal validity.
