Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Ironclad
- No published pricing; requires direct sales team contact for quotes, preventing cost comparison before engagement
- No public information on pricing model (per-contract, per-user, or tiered); cost structure opaque
- Requires choosing between self-led implementation or paid deployment support; no true 'free trial' option available
- Pricing includes add-ons (API, integrations, additional instances) with no pre-published costs; total cost unpredictable
- Enterprise-only positioning suggests premium pricing with no entry-level option for smaller teams
Luminance
- No independent evaluation of its accuracy has been published, and it did not take part in the Vals Legal AI Report, so buyers have only vendor-produced evidence to work from.
- The one named accuracy benchmark, ContractIQ Bench, was built, run and scored by Luminance on a dataset it has not released, against comparison models it does not name.
- Value scales with document volume, so an organisation reviewing tens rather than thousands of contracts will not recover the licence cost.
- Output still requires qualified review, so it reduces reading time rather than removing the lawyer, and staffing plans that assume otherwise fail.
- Pricing is not published, so cost per matter cannot be modelled until after a sales process and a proof of concept.

Answered from the vendors’ own pages
Ironclad: What is Jurist?
Jurist is an AI assistant built specifically for legal contract review and research, helping teams analyse contracts and surface key terms.
SourceLuminance: Is Luminance's accuracy independently verified?
No independent verification has been published. It did not participate in the Vals Legal AI Report, the main lawyer-baselined benchmark, and the only named benchmark in its materials is one it built and ran itself. Treat the published figures as vendor claims and run a proof of concept on your own documents.
Ironclad: Does Ironclad integrate with Salesforce?
Yes. Ironclad integrates with Salesforce, Slack, Microsoft Word, Coupa, Zapier and numerous other enterprise tools.
SourceLuminance: What do the ninety per cent time-saving claims mean?
They are unattributed marketing figures about time and cost rather than accuracy, published without methodology, dataset or baseline. They are not a measure of how often the software is right.
Ironclad: Is there a free trial available?
Pricing is not published. Interested organisations should request a demo to discuss their contracting needs and receive a custom quote.
SourceLuminance: Who backs Luminance?
It launched in 2016 with backing from Invoke Capital, the fund founded by Mike Lynch, and has since raised further rounds led by March Capital and Point72 Private Investments.
