Every Document Task. One Platform.

Built for Enterprise Security from Day One.
Your documents never leave your environment. JR3 meets the strictest enterprise security and compliance requirements — so your legal team can move fast without compromising on data privacy.
Junior is not a generic chat interface or a single-purpose drafting tool with AI bolted on top.
It's built on Junior's flagship patent AI drafting platform — developed by attorneys and engineers for the most precise, demanding legal writing that exists. Patent drafting demands structural accuracy, technical depth, and strict consistency across long, complex documents. That same foundation powers everything in-house legal teams produce, from NDAs to governance frameworks.
Join the Early Access Program.
We're partnering with a select group of in-house legal teams ready to replace fragmented, time-consuming workflows with one intelligent platform. Spots are limited.
Common Questions
Is our data used to train shared models?
No. Your documents and inputs are never used to train any shared model. All fine-tuning stays within your firm's isolated environment.
How does J3 integrate with our document management system?
JR3 works natively inside Word and Google Docs. Integrations with leading DMS platforms are on the product roadmap.
Which AI models power J3?
JR3 runs on GPT, Claude, and Gemini — each fine-tuned for legal drafting. Your team controls which models are active and when.
How do we control outside counsel access?
Firms create scoped access profiles that restrict what outside counsel can generate or view — without exposing internal documents or training data.
What happens to our documents after processing?
Documents are processed in transit and not retained beyond the session. Your firm controls data residency and retention policies.
What security standards does J3 meet?
JR3 meets enterprise security and privacy requirements. Full documentation is available at junior.law/security.
