In-house legal teams are facing unprecedented demand. As organisations expand across jurisdictions and business units, legal is expected to do more with the same, or fewer resources. According to EY, 70% of General Counsel now consider legal self-service tools critical to managing rising workloads, yet 85% of legal tasks still go unsupported across the enterprise.
Marketing and commercial teams are under pressure to launch faster, yet legal oversight remains essential to protect the brand and mitigate regulatory missteps. The result? Bottlenecks, delays, and missed opportunities.
Plexus Knowledge is purpose-built to close these gaps
Instead of storing policies in disconnected folders or static PDFs, Plexus Knowledge turns legal, compliance, and brand rules into an AI-powered guidance engine, embedded directly into the workflows your teams use every day.
Not all legal AI is equal
Generic AI tools rely on publicly available data and generic rule sets. Plexus Knowledge is trained on your policies, precedents, and risk frameworks — so guidance is always accurate, relevant, and aligned to your organisation’s standards.
And unlike traditional review workflows that slow things down, Plexus accelerates them, cutting legal review volumes by up to 40%.
For legal leaders
Traditional legal review models require teams to triage everything. Plexus flips that model.
By embedding your playbooks into real-time workflows, Plexus can:
-
Automate repetitive, low-impact work: AI handles early-stage reviews and standard approvals, allowing legal to focus on high-risk matters.
-
Reduce intake and free capacity: Guided, compliant self-service workflows empower business teams to handle low-risk tasks.
-
Enforce rules and consistency: Centralise rules, templates, and precedents in one platform, ensuring everyone follows the same guidance.
-
Be audit-ready with every approval tracked, timestamped, and backed by your defined governance logic.
Legal teams can’t review everything but everything still needs to be right. Plexus Knowledge delivers targeted oversight without becoming a bottleneck.
For marketing and commercial leaders
Marketing and commercial teams are measured on speed, reach, and impact. However, campaign momentum often stalls while waiting for legal signoff, leading to missed market windows and costly agency rework.
With Marketing Wizard + Knowledge, that friction is removed.
-
Early issue detection: Flag and fix compliance risks at the concept and creative process, avoiding costly rework and missed deadlines.
-
Risk-based routing: Automatically clear low-risk content and escalate only high-impact campaigns to legal.
-
Compliance without compromise: Embed legal and brand checks directly into creative workflows to maintain momentum across teams and geographies.
What’s working in the background
Every asset is instantly reviewed against:
-
230+ Australian laws, advertising codes, and industry regulations
-
Your organisation’s brand guidelines, policies, and legal playbook
-
Knowledge documents are weighted by risk, enabling Plexus AI to focus on what matters most
-
Upload your rules: Bring in legal precedents, brand standards, and compliance frameworks
-
Review instantly: Teams get real-time, in-flow feedback on every submission
-
Escalate only when needed: Legal is notified only for high-risk or edge-case scenarios
One source of truth
Plexus Knowledge replaces fragmented guidance systems with a single, governed platform.
Legal can update rules instantly. For contracts, changes apply to all future reviews of that document type (e.g. NDAs). For marketing updates, they sync across all campaigns and assets. Every action is tracked, timestamped, and audit-ready by default.
Backed by results, built for scale
Plexus is trusted by leading enterprises across Australia, New Zealand, and Singapore, including Woolworths, PepsiCo, Lion and Powerco.
Our Knowledge & Precedents engine powers millions of workflow decisions annually, with proven results in real-world legal, compliance, and marketing environments.
With Plexus AI and built-in Knowledge, in-house legal teams can handle more without hiring more, delivering the speed the business needs with the control legal requires.
