How key features work

AI features

Parts of the site talk to AI services or AI endpoints (OpenAI API, /v1/chat/completions, /v1/completions, /v3/openai/chat/completions and 1 more). Text you type there may be sent to them.E20E37E38E39

OpenAI API/v1/chat/completions/v1/completions/v3/openai/chat/completions/api/paas/v4/chat/completions

Payments

Payments are handled by Stripe and Stripe.js, so card or payment details go to them, not only to this site.E7E9E10E19

StripeStripe.js

Loading its content

Limits

  • We only see what your browser sees: code and requests on a first visit, without logging in or accepting cookie banners. What the servers do with data is invisible from outside.
  • Site code is usually minified (compressed), so names are partly lost and some code may be only partly analysed.
  • Some trackers only load after you accept cookies or log in, so the real list can be longer.
  • We visited from a server in the United States. Sites load different trackers and cookie banners in different countries (visitors in the EU usually get a consent banner first).
  • The tech check compares the site's own words with what its public page loads. Work done on servers, in private code or in separate apps isn't visible here, so 'nothing found' means not visible on the public page, not that it doesn't exist.
  • This text was written from fixed templates because no AI writer was available. It uses exactly the same evidence.
  • REA hit its size budget on parts of 8 large bundle file(s); those parts weren't fully analysed.

Facts, not judgements: this page describes what the code and traffic show, not anyone's intent. Not financial advice. Case id J1Y17rBE.
