You can import exhibits straight from the third-party document repositories your firm already uses — Clio, Box, and Dropbox (and, on some plans, Relativity and NetDocuments).
First connect the service. Open the account menu in the top-right corner, choose Account Settings, then go to Advanced → Integrations and click Connect next to the service you use. Integrations are a paid feature.
Once a service is connected, an Import from [service] option appears in the NEW menu on the case and deposition pages. Choose it to browse that repository and pick documents to bring in. The import runs in the background, and you'll get an email when it finishes.
