The short version

  • Each has a real cost: Actionstep no pricing is published beyond a rough $60 a month starting figure; real cost including implementation and add-ons requires a sales quote and can rise substantially, as one documented case showed a fourfold increase within a year.; 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.
  • They diverge on capability: Actionstep covers Configurable workflows, Luminance covers Anomaly detection.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Actionstep

  • No pricing is published beyond a rough $60 a month starting figure; real cost including implementation and add-ons requires a sales quote and can rise substantially, as one documented case showed a fourfold increase within a year.
  • The configurability that is the main selling point means implementation is a genuine project requiring firm time to design workflows, not a same-day signup like more templated competitors.
  • Legal Accounting is sold as a separate North America-only product, so international firms cannot get the full accounting feature set through the same purchase.
  • Reviewer base skews heavily toward small firms, and Actionstep itself is candid that most of its reviews come from small businesses, which is a signal about where the product is proven at scale.
  • Add-on modules (Builder, Capture, Trace, Acumen) are each additional cost, so a firm comparing Actionstep to an all-in-one competitor needs to price in modules separately to get a fair comparison.

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

Actionstep: Is Actionstep pricing published?

No. The pricing page gives no rate card; you must request a quote, and cost is per user plus implementation fees, varying by region.

Luminance: 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.

Actionstep: Can I buy just the accounting product?

Yes, Legal Accounting is sold separately from Practice Management, though it is limited to North America.

Luminance: 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.

Actionstep: Does it work like Clio or MyCase out of the box?

Not exactly. Actionstep leans on firm-configured workflows rather than fixed templates, which means more setup but a closer eventual fit to how the firm works.

Luminance: 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.
