Is teleprompt AI – Prompt Generator & Optimizer safe?

Medium risk

teleprompt AI sends scraped page email addresses and prompt text from supported AI/chat sites to Mixpanel.

On supported pages, its content scripts scan page text, HTML, and inline scripts for email addresses and send matches in an extension_loaded Mixpanel event with the page hostname. When a user clicks the Improve button, the extension reads the current prompt, truncates it to 1,000 characters, and sends prompt_text, score, and host metadata to api-js.mixpanel.com.
