This appears to be a legitimate SEO tool, but its privacy documentation contradicts itself about whether user content is sent to outside AI providers.
Review before installing if you will analyze confidential, regulated, proprietary, or customer content. Treat the actual behavior as external AI-provider processing: excerpts of your content are sent to the model provider selected by the model name, using your API key and that provider's retention and privacy rules. The publisher should correct the contradictory no-external-transmission and no-third-party-sharing claims before users rely on its privacy posture.
