The platforms closed matters sit in

E-discovery data and AI: what review platforms' terms say

Most of a litigation archive lives in a review or processing platform. Its terms decide what the firm can take out, and what the platform may do with what was loaded.

Ask about the firm's material

Ownership of what is loaded

Reveal (Logikcull): The customer is and will remain the sole and exclusive owner of all hosted data.
Casepoint: The customer owns all customer data and keeps the liabilities of collecting and holding it.
Nuix: As between Nuix and the licensee, the licensee owns the licensee data.

AI training

5 platforms on our board say they will not train on a firm's material. LexisNexis states that subscriber inputs will not be used to train any large language model, and Casepoint that it will not use AI inputs and outputs for AI training without customer approval.

Leaving the platform

Logikcull makes hosted data available for export or download for up to thirty days after the subscription ends, then deletes it.
Casepoint offers an export of all customer data in a common format of its choosing on termination.
Harvey securely deletes remaining customer data within 30 days of termination unless told otherwise.

An export is the firm's copy, not a licence to share it: the client's confidence goes with it. The rules are on who owns the client file.

Describe the firm's closed matters

A client's file needs that client's release; the firm's own precedents do not. Tell us which material you mean and where it is held, and we will reply in writing.
