The product

Read every clause. Never the same one twice.

ZAAN reads contracts the way a senior associate would — and surfaces only what deserves your attention. Built for teams that bill by the hour but live by the line.

Capabilities

Three surfaces, one quiet engine.

Every part of ZAAN is built around the same idea: legal work is best when the tool gets out of the way. We move fast for you, then disappear.

Review

Open a draft. ZAAN reads it against your playbooks, flags risk, and suggests redlines you can accept inline. Click any flag and read the reasoning. Disagree, and we learn.

REVIEW.ENGINE · v4.2

Draft

Compose new contracts from your firm's house style. ZAAN drafts the boilerplate, you spend your hours on the deal points. Every output is fully cited and tracked.

Recall

Ask anything across your matter history. "How did we handle MAC clauses for tech buyers in 2024?" Answers come with the precedents, in seconds.

How it works

Four steps. No retraining.

ZAAN slots into the tools you already use — Word, iManage, NetDocuments, DocuSign. Most teams are reviewing live deals on day three.

i.

Connect your DMS

One-click integrations with iManage, NetDocs, SharePoint. We never copy what we don't need.

ii.

Upload your playbook

Drop in your house style. ZAAN learns clause preferences, fallbacks, and red lines.

iii.

Review in Word

The plugin lives where you live. Flag, accept, redline — without leaving the document.

iv.

Close, then learn

Every closed deal sharpens future reviews. Your team's judgement, codified.

In their words

From the people who actually use it.

We don't run testimonials past marketing. These are unedited, on the record, and from teams who renewed.

"We didn't replace anyone. We just stopped losing weekends. The associate who used to dread Friday afternoons now looks forward to them."

"The reasoning panel is the part nobody else builds well. I can audit the AI in five seconds. That's why my GC let us deploy it."

"The translation layer alone is worth it. We close cross-border deals where neither side speaks English natively, and ZAAN keeps both halves of the contract honest."

"We piloted three platforms. ZAAN was the only one whose suggestions our partners actually accepted. The voice is right."

Notes from the workshop.

We don't blog. Occasionally we publish something worth your time — a piece of research, a release note, a long answer to a question we've been asked too many times.

How we evaluate clause-level reasoning without leaking the contract.

A long-form piece on our internal eval harness, written by the research team. Includes the synthetic dataset we use and how we audit it.

What three months in Lagos taught us about pro-bono software.

precision • simplicity • intelligence

Worth ten quiet minutes of your week.

We don't do demo theatre. Send us a contract you've already reviewed, and we'll show you what ZAAN sees in it. If we waste your time, tell us — and we'll send a bottle of something to apologise.
