Arca
Product Agent

The execution engine for legal work.

Arca Agent plans, executes, reviews, and delivers complex legal tasks end-to-end — handling multi-step work across documents, data sources, and systems while keeping your team in control at every step.

How it works

A paradigm shift in how legal work gets done.

Agent moves through four phases on every task — planning an approach, executing the work, reviewing against your standards, and delivering a finished product.

Phase 01

Plan

Analyzes the request, selects tools, and proposes a clear strategy before taking a single action.

Phase 02

Execute

Runs multi-step work across contracts, databases, and communication systems without switching tools.

Phase 03

Review

Evaluates its own output against your standards, adjusting iteratively until the goal is fully met.

Phase 04

Deliver

Produces finished work products — redlines, summaries, approvals — ready for human sign-off.

Capabilities

Purpose-built for legal complexity.

Agent goes beyond task automation. It reasons through nuanced legal work the same way a skilled lawyer would — methodically, with full context.

Autonomous tool orchestration

Agent coordinates search, drafting, redlining, and review across your connected systems without manual hand-offs between tools.

Cross-system

Skills encoding your processes

Encode firm-specific standards, playbooks, and institutional knowledge directly into Agent's behavior so every task reflects how your team decides.

Institutional knowledge

Transparent planning and control

Every plan is visible before execution begins. Approve, modify, or stop work at any stage — Agent never acts without a clear path you can inspect.

Human-in-the-loop

Proactive monitoring

Agent watches ongoing matters, contracts, and communications — surfacing actions needed before stakeholders have to ask.

Continuous
Operating model

End-to-end execution, with a human always in the loop.

Connect your systems

Agent works across Slack, email, CRM, Jira, contract repositories, and document systems — pulling context from wherever it lives.

Apply your standards

Encode approved positions, playbooks, fallback language, owner rules, and escalation thresholds so every task reflects your policy.

Close the loop

Finished work, approvals, and lessons learned are written back to the systems your teams already use — no separate tracking required.
