Is Youtube Summary With AI safe?
Youtube Summary With AI sends page URLs and video metadata to PostHog analytics when users trigger AI features.
When a user requests a YouTube video summary, the extension captures the current page URL and video metadata and transmits them to PostHog via a hardcoded project key. Additionally, JavaScript errors occurring on supported AI chat sites (ChatGPT, Claude, Gemini, Grok, Mistral) also send the page URL and error details to the same PostHog endpoint. Both flows use a persistent random client ID stored locally to identify the user across sessions.
