Lighthouse Prism

Quickly analyze large document volumes with the precision you need. Lighthouse Prism uses natural language processing and deep learning AI models to perform a nuanced analysis of your documents. Learning in real-time, Prism identifies privilege and sensitive company information so you can fulfill the requirement of your HSR Second Request in time and with peace of mind.


Automate steps that aren’t a good use of attorney time and organize information for quick validation and execution. Created with the DOJ’s privilege log requirements in mind, PrivSmart normalizes names and generates a log of privileged materials in a matter of minutes. It also provides a user-editable search term list to find and group potentially privileged documents to determine treatment of each set.
