Ironclad combines contract workflows with AI playbooks. Lexnus makes policy the independent control layer.
Ironclad combines workflow automation, approvals and AI-assisted playbook review. Lexnus starts with a published legal policy and evaluates contract values against deterministic rules.
The difference in one line
Why the starting point decides everything
A workflow tool answers a routing question. It knows the deal needs three approvals, it knows whose turn it is, and it chases them. That is genuinely useful, and it is the reason approval automation sells.
Ironclad can also analyse contract language against AI playbooks. The difference is how that contract analysis relates to the organisation’s policy.
Ironclad can identify non-standard terms and route them for approval. Lexnus takes a different approach: the approved policy is published as versioned rules, and extracted contract values are evaluated against those rules.
Lexnus asks the prior question. Before anyone routes anything, the engine evaluates the contract against your published playbook and returns a verdict per rule. The cap fails, and fails with the clause text that caused it and the rule it broke. The reviewer is not being asked for judgement. They are being told what breaks.
The two are not mutually exclusive. Routing is a process problem and policy is a standards problem. What you should not do is buy the first and assume you got the second.
Side by side
| workflow automation | Lexnus | |
|---|---|---|
| Where the product starts | The approval process | The published policy |
| What it knows about a contract | Workflow state, contract data and detected clauses | Whether every rule passes or fails |
| When a bad term is caught | During AI playbook review or human review | Before the contract leaves, on every analysis |
| Setup work before value | Model your approval workflow | Upload one contract; a playbook is drafted for you |
| Who can be trusted to act alone | Whoever the workflow routes to | Business users, because the engine holds the line |
| What the audit trail proves | Who approved, and when | Which policy version judged it, and what it said |
This page describes an architectural difference, not a feature scorecard. Products change; for what any vendor ships today, read their own documentation. What does not change is where each one starts, and that is what this page is about.
When Ironclad is the right answer
You need approval routing, entitlement matrices and stage gates across many departments, and policy enforcement is genuinely not the problem you are solving.
We would rather tell you that than sell you the wrong layer. Every CLM started with the document. Lexnus started with the policy. If the policy is not what is failing you, this is not the product to buy.
Questions
Can we run both?
Yes, and some teams should. Lexnus governs what the contract is allowed to say; a workflow tool governs who signs off on it. They answer different questions.
Where they overlap is the review step, and that is where Lexnus changes the economics: a reviewer reading a verdict instead of reading a contract is a much shorter step.
Does Lexnus replace approvals?
It replaces the reason most approvals exist. A large share of legal review is a human checking whether the paper matches the standard. When the engine does that deterministically, the remaining approvals are the genuine judgement calls, which is what you wanted your lawyers doing.
We already have a CLM. Is this a migration?
No. Lexnus does not need to own your documents to govern them. Point a surface at the engine (the application, Word, or an agent over MCP) and your policy is enforced where the work already happens.
See it on your own contract.
Upload one contract you have already signed. Lexnus drafts a playbook from it, and you can watch your own standard get enforced. Free plan, no card.
