PriorCall

Features

Four things it does.

Finds the conflicts

Deterministic rules sweep your whole client history and flag disagreements before opposing counsel finds them: privilege calls that contradict, responsiveness that flips, and the FRE 502 trap.

Inherits the prior call

Review starts 30% to 60% done. Anything the firm already coded for this client arrives with its previous call and the reasoning. A human still makes the decision of record.

Shows its work

Every match names the tier that produced it: native hash, normalized text, near-duplicate or threading. You can tell a judge exactly why two documents matched, without a confidence score to defend.

Feeds your review platform

Overlays export with PriorCall_-prefixed columns, so a suggestion can never overwrite a decision of record. Works with Relativity, Everlaw, DISCO, Nextpoint and anything else that reads load files.

Built so a carrier's IT questionnaire is a formality.

Metadata only, by design

No document body, attachment or line of text ever enters the system. There is nothing sensitive to leak, because the sensitive part never arrives.

Deterministic, with no model in the matching path

Nothing is trained on your data, and no probabilistic guess decides whether two documents are the same. The matching is code, and you could audit it line by line.

Isolation that fails closed, tested on every build

Row-level security and client-scoped keys, plus an adversarial cross-tenant test that has to pass on every commit before anything ships.

Hash-chained audit log

Every decision is traceable, and the chain is what makes tampering show.

US-region hosting, full export, month to month

There is no per-gigabyte meter and nothing held hostage. Cancel whenever you like and take all of it with you.

Decisions of record stay human

PriorCall suggests; it never overwrites a coding call. That posture is deliberate, and it comes from FRCP 26(g) and ABA Opinion 512 rather than from taste.

One firm, one client, one vault.

Your carrier clients are sometimes each other's adversaries, so the boundary between them is structural rather than configured. Row-level security that fails closed, composite keys that make a cross-client reference impossible to write, and queries that take client scope as an input.

An adversarial test seeds two clients with byte-identical documents and asserts zero crossover. It runs on every build and has never been allowed to fail. There is no switch to leave off.
