What does Rule 1.6(c) require when a firm uses AI?
Rule 1.6(c) requires lawyers to make reasonable efforts to prevent the unauthorized disclosure of client information — it does not prohibit the use of AI. ABA Formal Opinion 512 (July 2024) and North Carolina 2024 FEO 1 (November 2024) both confirm that AI use is permitted under the existing duties of competence, confidentiality, and supervision. What the rules impose is a diligence burden: a firm has to understand where client data goes, who holds it, and whether it trains someone else's model.
That burden is exactly what a private deployment collapses. When the AI runs inside the firm's own environment, the confidentiality analysis shifts from vetting an outside vendor's data practices to applying the firm's own controls — a question firms already know how to answer.

How is Deepvine different from ChatGPT or Copilot for a law firm?
The difference is the environment: Deepvine runs in your infrastructure instead of a shared public cloud. General assistants like ChatGPT and Copilot are powerful, but they were built for the open internet, not for a firm that has to account for where every client document travels.
Deepvine connects to your document management system, email, and Slack, and it is backfilled with your firm's own matter history so its answers come from your work product rather than the public web. Your data stays in your control, and your inputs are never used to train models that other organizations share. The result is an assistant that actually knows your matters, your precedents, and your institutional history — not a generic one you have to keep re-explaining your practice to.
What can attorneys actually do with it?
Attorneys use Deepvine to find and reuse the firm's own knowledge without hunting through folders or emailing colleagues who may have left. Because the system is grounded in the firm's actual documents, every answer points back to its source.

- Institutional knowledge from departed partnersrecover the reasoning and history that used to live only in one person's head.
- Conflicts contextpull the background a lawyer needs to understand a party or prior engagement quickly.
- Grounded draftingdraft briefs and memos anchored in the firm's own work product rather than generic language.
- Source-cited answers in Slackask a question where the team already works and get an answer with citations back to the underlying documents.
What does deployment look like?
Deployment is a managed process, not a weekend software install. It moves through four stages: connection, backfill, daily diffs, and ongoing maintenance.
First we connect Deepvine to your existing systems. Then we backfill your historical matters so the assistant starts with real institutional memory instead of a blank slate. From there, daily diffs keep the knowledge base current as new documents and messages are created, and we handle managed maintenance so your team is not responsible for operating the system.

Which firms is this built for?
Deepvine is built for firms of roughly 10 to 75 attorneys in document-dense practices where institutional memory is concentrated in a handful of people. That is the range where a firm has enough accumulated work product to make retrieval genuinely valuable, but not so much internal engineering that it would build this itself.
If your practice produces a heavy volume of documents, relies on precedent, and would feel real pain if a senior partner retired tomorrow, this is built for you. You can read more about who we are and why we build this way on our about page.
FAQ
Frequently asked questions
Does our data ever leave our environment?
No. Deepvine is deployed inside your firm's own infrastructure, and your documents, matters, and prompts stay there. The system connects to your existing tools and reads your work product in place; nothing is copied to a shared cloud, and your inputs are never used to train models that other organizations touch.
Can we use it with our document management system?
Yes. Deepvine is built to connect to the systems a firm already runs on, including document management, email, and Slack. Rather than asking attorneys to upload files into a separate tool, it indexes the firm's existing repositories so answers are grounded in the actual matter record.
What happens to the system if we end the engagement?
You keep your data and the knowledge base built on it, because both live in your environment from day one. Deepvine runs on infrastructure you control, so ending the engagement means we stop managing and maintaining the system, not that your firm's institutional memory walks out the door with a vendor.
How long does backfill take?
Backfill timing depends on the volume and format of your historical matters, but the connection and initial indexing are typically measured in weeks, not months. Once the backfill completes, daily diffs keep the system current as new documents and messages are created.
Does this satisfy our ethics obligations?
Deepvine is designed to support the reasonable-efforts duty under Rule 1.6(c), but no vendor can guarantee compliance on your firm's behalf. A private deployment removes the hardest parts of the confidentiality analysis by keeping client data in your control and out of shared model training; your firm remains responsible for its own supervision, competence, and security decisions.
What does it cost?
Pricing depends on firm size, the systems being connected, and the depth of historical backfill, so we scope it during the demo rather than list a single number. The engagement is structured as an ongoing managed service that includes deployment, maintenance, and updates.
