The platform

Ready-made legal intelligence, used on day one.

The Atherna Platform is the full stack teams run as-is: unlimited ingestion, research, drafting, and a matters workspace, configured to how your practice already works. No pilot that never ships. You bring the matter; Atherna does the work.

What you get

One platform. Every surface.

The complete legal-intelligence stack, configured to your practice and ready the day you log in, not a roadmap of features to wait for.

Unlimited ingestion

No context, upload, or format ceiling. Drop an entire matter (thousands of contracts, filings, and discovery sets) and Atherna reasons across all of it at once.

Research

Precedent, statute, and regulator guidance with semantic depth across every jurisdiction you practice in. Every answer is cited; every citation is verifiable in one click.

Drafting + drafting editor

First drafts of agreements, opinions, and submissions in your house style, then a clause-by-clause editor to redline, ground, and finish the work to the standard of counsel.

Matters workspace

One workspace per matter that holds the record, the research, and the drafts together, so the whole team works from the same source, with a full audit trail.

Memory

Atherna remembers your precedents, positions, and preferred language across matters, so the second engagement starts ahead of where the first one ended.

Integrations

Native integrations into each region's regulators, plus the document and knowledge systems your team already runs. The platform fits your stack, not the other way round.

In the product

Built to the standard of counsel.

Two surfaces lawyers live in every day, the matters workspace and the drafting editor, engineered for the volume and stakes of real legal work.

Matters workspace

The whole matter, in one place.

Every matter gets a workspace that holds the full record alongside the research and the drafts. Ask a question and the answer is grounded in the documents you loaded, with the source on the right, ready to open.

  • Reason across the entire record, not a sampled subset
  • Sources on the right; open any citation in one click
  • Shared workspace with a complete audit trail

Drafting editor

Draft, redline, and finish in your voice.

Generate a first draft in your house style, then work it clause by clause in the drafting editor. Every line stays connected to its source, so you can check the basis for a position without leaving the page.

  • First drafts in your house style, not a generic template
  • Clause-by-clause editing with the source attached
  • Track positions and preferred language across matters

Why it holds up

Reliable where the stakes are highest.

Most legal AI caps what you can load and loses the thread at scale. Atherna is built the other way, for the full record, with the discipline a serious matter demands.

Cross-document reasoning

Load the entire matter and Atherna reasons across all of it, surfacing conflicts, missing clauses, and the through-line others lose at volume.

Verified citations

Every claim is grounded in a source passage and verifiable in one click, so you can rely on the output where it counts.

House-style preservation

Drafts come out in your firm's voice and conventions, learned from your precedents, not flattened into a generic template.

Full audit trail

Every step is recorded: what was asked, what was retrieved, what changed. The trail high-stakes matters require, ready for review.

Onboarding

Live in weeks, not quarters.

A ready-made platform still earns its place by fitting your practice. Three steps take you from first call to lawyers working in production.

01

Scope and connect

We map your matter types, house style, and systems, then connect the platform to the documents and regulators your team already works with. Your data stays yours.

02

Configure to your practice

Atherna is tuned to your precedents, templates, and review standards, so the drafting editor writes in your voice and research reflects how your firm reasons.

03

Go live with your team

Lawyers start on real matters with hands-on onboarding and an Atherna team behind you. You are working in production in weeks, not quarters.

Security & trust

The first legal AI in the world to clear a bank's ISG review, and hardened since.

Your work is never retained or used for training. Zero data retention by default, customer-managed keys, and a posture that has already satisfied the IT, risk, and security functions of a publicly listed bank.

Trusted by the teams that cannot be wrong.

Relied on by publicly listed banks, Supreme Court counsel, and international arbitrators, and independently judged the most reliable AI for legal work.

We needed a pan-India stamp-duty engine and the Atherna team delivered it in four days. The regulator integrations have transformed our compliance work, and unlike every other legal AI we tried, it never cites repealed circulars.
