Your independent AI shopping agent

Paste an AI shopping recommendation from ChatGPT, Claude, Gemini, or Rufus — or just describe what you're looking for. Lens verifies every claim against live product data, shows the transparent spec-optimal pick, flags confabulations, and checks what other frontier models picked.

Grounded in peer-reviewed research: 18 AI models, 382,000 shopping trials, submitted to Nature. AI shopping assistants pick non-optimal products 21% of the time and confabulate reasons 86% of the time.
