If you like the assistant, show your appreciation with a small contribution:


Data protection & implementation

  • Chats are not saved permanently.
  • The bot is based on the ChatGPT-4o Mini model, controlled via a precise system prompt.
  • The payment function runs via Stripe, GDPR-compliant & encrypted.
  • It is also possible to implement this type of bot without passing on the input data to OpenAI. The implementation costs are similar, but the maintenance costs are generally higher.

It is based on:

  • a well thought-out, learning-effective system prompt
