Longitudinal Lab

Longitudinal measurement programs: how AI systems retrieve, interpret and recommend companies and institutions over time.

AI Retrieval Observatory

First-party longitudinal research from exmxc measuring how Google generative AI retrieves evidence, frameworks, and knowledge objects across controlled web properties.

The Entity Clarity Index (ECI) publishes institutional industry reports measuring how companies are interpreted, trusted, and surfaced by AI systems—guiding executives, investors, and operators in the AI-search era.

Entity Clarity Review tool

Run a deterministic Entity Clarity Review across identity resolution, entity consistency, relationship clarity, evidence traceability, and machine legibility. No model API is called.

AI Commerce Exposure

AI Commerce Exposure measures whether retailers enter AI-generated shopping consideration sets and how prominently they rank, while keeping access, product legibility, integrations, recommendation presence, transaction accessibility, and owned AI capability as separate variables.
