The short version

  • Each has a real cost: Logikcull built for self-service, so very large or complex matters still favour the enterprise platforms; 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: Logikcull covers Automated processing, Luminance covers Anomaly detection.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Logikcull

  • Built for self-service, so very large or complex matters still favour the enterprise platforms
  • Analytics and predictive coding are lighter than Relativity or Everlaw
  • Acquired by Reveal, and roadmap direction under new ownership is a fair question for a buyer
  • Per-matter pricing is predictable but not always cheaper on small collections

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

Logikcull: What does Logikcull cost?

It publishes per-matter and subscription pricing, which is unusual in ediscovery and is much of its appeal.

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.

Logikcull: Do I need a specialist to run it?

No. Processing is automated and review runs in the browser, which is the difference from platforms where certification is a job title.

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.

Logikcull: When is it not the right tool?

Very large or analytically complex matters, where Relativity and Everlaw have deeper review and predictive coding.

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.
