Everything here works offline — like the product.

Start private search in three steps.

Download LatticeSearch, choose the folders to index, then search by what you remember. The name index comes online fast; deeper image, document, audio, and video understanding fills in quietly in the background.

Getting started

Download, index, search.

Install

Install LatticeSearch on a normal Windows 10 or 11 PC. The app is designed for local search, so no cloud account is required for search.

Choose scope

Select the folders, drives, or workspaces you want LatticeSearch to understand. Your files and index stay on the machine.

Ask naturally

Search for "the invoice from March", "golden-eyed cats in London, 2025", or "the clip where the red car enters".

Connect

MCP, REST API, and CLI surfaces.

AI tools can ask LatticeSearch for relevant spans instead of reading whole files. One context call returns the precise passage, timestamp, or region with provenance.

MCP

For agents

Expose local search, context, file discovery, and safe provenance-aware reads through MCP tools.

REST

For apps

Call the local API to search by meaning, combine attributes, and retrieve context for any model.

CLI

For scripts

Use commands for search, indexing, context retrieval, and automation from terminals or build agents.
