Arca
Product Legal Research

Ground every answer in authoritative sources.

Arca searches across trusted legal databases, statutes, case law, regulations, and your internal precedents to produce cited, verifiable research — fast enough for the pace your business moves.

Research sources

Three powerful sources. One unified answer.

Whenever you ask a question, Arca draws on three research streams simultaneously — internal context, trusted legal content, and the open web — then synthesizes a single, cited response.

Internal databases

Draw on your contract history, playbooks, approved positions, and prior decisions — so research is grounded in how your organization has already decided.

Trusted legal content

Access authoritative case law, statutes, regulations, legal guidelines, and reference materials through Arca's content partnerships.

Open web

Scan current regulatory guidance, enforcement notices, public filings, and news — keeping research current without manual monitoring.

How it works

From question to verified answer.

Research in Arca moves in three steps — from the question you ask to a fully cited response grounded in authoritative sources.

01

Ask in plain language

Pose any research question — a jurisdictional question, a clause comparison, or a regulatory analysis — directly in the Arca interface.

Cited answer delivered

Every answer traces back to its source. Click through to the original material — no guesswork about where a conclusion came from.

Fully cited

Unlike general-purpose AI tools, Arca connects research directly to your workflow — so findings flow into drafts, memos, and approvals without copying and pasting between tools.
