FAQs
What is Lighthouse AI Search?
Lighthouse AI Search is an advanced eDiscovery search tool that uses both predictive and generative AI to answer natural language questions using your document population.
How does it differ from traditional search tools?
Unlike Boolean keyword-based searches, Lighthouse AI Search doesn’t require you to know what to ask in advance. It reads your documents and surfaces grounded, citation-backed insights.
Is prompt engineering required to use Lighthouse AI Search?
No. Lighthouse AI Search was built so users can ask questions in the same way they might ask an associate or search consultant.
What eDiscovery workflows is AI Search best for?
It’s built for every phase of a matter—early case assessment, inbound production review, deposition and trial prep, and more.
What if I want to make sure I have all of my key documents?
The Lighthouse Search team can pick up where you left off with AI Search. Our team’s methodological and linguistically-informed approach finds all of the documents that pertain to a topic, as well as the fewest number of documents that tell the full story.
Is my data secure?
Yes. Lighthouse AI Search is hosted in a secure, cloud-native Azure environment. Your data is never used to train the AI models.
