Build your own legal AI on a foundation that already works.
Most teams face a false choice: spend two years building legal AI from scratch, or ship a tool that never earns a lawyer's trust. Build on a harness that already handles the hard parts, with a dedicated engineering team building alongside you.

Two bad options. A third way.
In-house teams building legal AI usually pick between slow-and-expensive and fast-but-sub-par. Atherna gives you neither.
Build it yourself
Stand up ingestion, retrieval, drafting, memory, evaluation, and security from zero. Hire a team that has never shipped legal AI. Spend quarters before a lawyer sees an output worth reviewing.
Slow. Expensive. Years to parity.
Ship something sub-par
Wrap a model in a chat box and call it a platform. It demos well and fails on the matter that matters: capped uploads, lost context, citations no one can verify. The team quietly stops using it.
Fast to launch. Fast to abandon.
Build on the harness
Start from a foundation that already does the hard work, then build your own legal AI on top (your interface, your workflows, your house style) with an Atherna engineering team beside you.
In production in weeks. Built to the standard of counsel.
Our entire stack, as components.
Everything that runs the Atherna platform is available to build on. You take the pieces you need and build your own legal AI on top, never starting from scratch.
Unlimited ingestion
No context, upload, or format ceiling. Push an entire matter in and build on top of a model that reasons across all of it. Where most legal AI caps what you can load, Atherna does not.
Drafting + drafting editor
A drafting engine and a clause-by-clause editor you can wire into your own surfaces. Every output is grounded in source and reviewable line by line.
Memory
Durable matter and organizational memory your application reads and writes, so your legal AI remembers the deal, the precedent, and the house position across sessions.
Research
Semantic research across statute, precedent, and regulator guidance in the jurisdictions you practice in. Build it into your workflows and every answer arrives cited.
Matters workspace
The workspace primitives (matters, documents, threads, review state) exposed as components so you assemble the interface your team actually wants.
Integrations
Connect document stores, DMS, and native regulator integrations across the US, UK, Dubai, Singapore, and India, and extend the harness with your own.
An engineering team that builds it with you.
Every enterprise on the harness is paired with a dedicated Atherna engineering team. We do not hand you a toolkit and wish you luck: we build the tailored solution alongside your team.
Your workflows
We map the way your team actually works (intake, review, sign-off) and build the legal AI around it, not the other way around.
Your interface
The surfaces your lawyers see are yours. We build to your house style and your tools, so adoption is the default rather than the fight.
Our harness
The hard, expensive layers (ingestion, retrieval, drafting, memory, security) are already built, hardened, and maintained by us.
Co-built, not handed off
An Atherna engineering team builds with you and stays with you. This is the line that separates us from an off-the-shelf tool.
From scope to production.
A clear path from first conversation to a legal AI your team relies on, and a team that keeps building after launch.
Scope
We sit with your legal and technical leads to define the workflows, jurisdictions, and matter types that matter most, and what success looks like for your team.
Build on the harness
Your engineering team assembles your legal AI from Atherna components (ingestion, drafting, memory, research) with your interface and house style on top.
Integrate
We connect your document stores, DMS, and the native regulator integrations for your regions, then put it through your IT, risk, and security review.
Iterate
We stay on. As your matters and team evolve, the dedicated engineering team extends the build: new workflows, new surfaces, new integrations.
You own the surface. We own the depth.
The work your lawyers see is yours to design. Everything underneath (the ingestion that takes a whole matter, the retrieval that stays grounded, the security that clears a bank) is the harness, maintained and hardened by Atherna.
- Your interface and house style, built to your team's workflows
- Atherna components: ingestion, drafting, memory, research, matters
- Bank-grade security, citation rigor, and zero data retention underneath
Whatever you build inherits the foundation that became the first legal AI in the world to clear a bank's ISG review, and has hardened since.
Reliability and data security are not features you bolt on at the end. They are the layer your legal AI is built on: grounded citations, customer-managed keys, and zero data retention by default.
The same security and trust posture that satisfied the IT, risk, and security functions of publicly listed banks, documented for your own review.
Tell us what you want to build. We'll bring the team.
