Luminance was built as an AI review tool (not a CLM)

Luminance is mostly an AI-powered legal assistant for review and redlining, but it’s not built to handle the entire legal process.

  • No pre-signature capabilities
  • Built for small teams, not the enterprise
  • No way to set up automated legal workflows

Strong pre-signature capabilities

Intake forms, approval routing, workflow automation. Speed up everything that happens before signature.

Enterprise-level integrations

Ironclad natively connects with Salesforce, SAP, NetSuite, Coupa, and 70+ tools—and many more via API.

Frequently Asked Questions

What are the core differences between Luminance and Ironclad?

Luminance is an AI-powered review and redlining tool that pivoted to CLM. While they offer post-signature contract analysis, they lack pre-signature capabilities.

Ironclad is an end-to-end CLM built for the full contract lifecycle. You get AI for drafting, reviewing, and extracting data, plus the workflows, integrations, and collaboration features to manage contracts from request to renewal.

How do Luminance and Ironclad AI models compare?

Luminance uses a proprietary legal language model trained on over 150 million verified legal documents and is optimized for AI‑assisted contract review, negotiation, and portfolio‑level analytics.

Ironclad combines best‑in‑class LLMs with proprietary models that are specialized for contracts and the contracting workflows inside Ironclad’s CLM. Ironclad’s AI is embedded across the full lifecycle intake, drafting and negotiation, extraction and verification, and renewals and savings, so customers can draft, review, extract data, and make renewal decisions in a single workflow‑native platform.

How does Ironclad pricing compare to Luminance?

Luminance charges based on document volume:the more contracts in your repository, the higher your cost. This model can become expensive as your contract portfolio grows.

Ironclad uses user-based pricing, which stays predictable regardless of how many contracts you store or process. Your costs scale with your team, not your contract volume.

How mature are Ironclad’s end-to-end workflows (from request to signature)?

Ironclad’s workflow engine is built for enterprise complexity. Set up conditional routing based on contract type, value, or risk. Automate approvals across legal, finance, and business teams. Track every contract from initial request through signature and beyond.

Luminance has basic workflow capabilities. Pre-signature workflow automation is not a core strength.

Does Ironclad integrate with Microsoft Word?

Yes, Ironclad integrates with Microsoft Word. The integration allows you to open Ironclad documents in Word, finish your edits, and save the document back to Ironclad.

For teams that prefer a faster approach, Ironclad has a native DOCX editor that works in your browser with real-time collaboration, that eliminates the need for Word.

Ironclad also integrates with Google Docs. You can collaborate with others on Ironclad documents directly in Google Docs. When you’re done, you can publish the updated version back into Ironclad Editor.

What integrations does each tool support (eSignature providers, ERP, CRM)?

Luminance integrates with Salesforce, DocuSign, Adobe Sign, SharePoint, and a handful of data rooms. Prospects describe the Salesforce integration as limited.

Ironclad offers 70+ native integrations including Salesforce (4.7 rating on AppExchange), SAP, NetSuite, Coupa, plus API connectivity for custom integrations. eSignature options include built-in eSignature, DocuSign, Adobe Sign, and Dropbox Sign.

What eSignature options does Ironclad support?

Ironclad has a built-in eSignature option for teams that want everything in one platform. It also integrates with DocuSign, Adobe Sign, and Dropbox Sign if you prefer a third-party provider.

Luminance doesn’t have its own eSignature tool. It integrates with DocuSign and Adobe Sign only.

Can Ironclad handle complex enterprise requirements?

Yes. Ironclad serves over 2000 global companies with industry-leading security, compliance, and scalability requirements.
