The AI helper

When you press an AI button (context synonyms, compare and explain, reverse dictionary), the word, sentence or description you typed is sent to our server and on to an AI model via Vercel AI Gateway to generate the answer. We do not store it. Please do not paste personal or confidential text. Your IP address is held in memory briefly to limit abuse, then discarded.

Analytics

We use Ahrefs Web Analytics, a cookieless analytics service, to count page views and see which pages are useful. It does not use cookies or build advertising profiles.

Hosting

The site is hosted on Vercel, which processes standard request logs to run the service.
