Overview

Lucid Engine is a 2026-founded startup out of Colombes, France, built by founder and CEO Marine Depoorter, a former Wavestone and Societe Generale consultant, to help digital-first brands track their visibility inside AI answer engines instead of traditional search results.

The platform runs a 'Truth Layer' audit against a set of strategic prompts across engines including ChatGPT, Perplexity, and Google AI, scoring a brand's category gap and surfacing which sources and pages those engines cite when they recommend competitors instead. Findings come back as action briefs that translate the audit into specific fixes rather than a raw data dump.

Lucid Engine targets SaaS companies and e-commerce brands that depend on organic AI-driven discovery. A no-signup Free Checker gives a baseline score, a $29 One-Shot Snapshot delivers a full one-time audit, and an $89-a-month Monitoring plan adds weekly tracking across three AI engines for a single brand or market.

Key features

  • Free baseline visibility check with no signup required
  • Truth Layer audit scoring category gaps against named competitors
  • Weekly monitoring runs across ChatGPT, Perplexity, and Google AI
  • Source and citation discovery showing which pages AI engines pull answers from
  • Action briefs translating audit findings into specific fixes
  • Run history for tracking visibility changes over time

Cons
