Hendrik George
About this gig
Want an AI assistant that answers like your business does? I build custom GPTs configured with your instructions, tone, and documents, so they handle repeat questions and tasks for you.
WHAT YOU GET
- A custom GPT with clear instructions and a defined role
- Your documents added as knowledge files
- Conversation starters and a consistent tone
- Testing with real questions, plus fixes
- Optional actions that connect to your tools or APIs
- A short guide so you can update it yourself
WHO IT'S FOR
Founders, coaches, support teams, agencies, and creators.
HOW IT WORKS
Send your goals and documents. I confirm scope, build, test, and hand over.
Generic chatbots give generic answers. I build a custom GPT that knows your business, follows your rules, and answers the way your team would, so customers and staff get consistent help without waiting.
Questions? Message me before ordering.

FAQ
What is a custom GPT?
A version of ChatGPT set up with your instructions, files and tone so it answers about your business consistently. It lives inside ChatGPT and is shared by link.
What files can you use as its knowledge base?
Common formats such as PDF, Word, text and spreadsheets. Send your FAQs, guides or policies, and I’ll organize them so the assistant can use them well.
Can you connect it to my website or an API?
Website embedding and API connections are different from a standard custom GPT, so message me first. The Premium package includes simple actions where supported.
Can delivery be rushed?
Often yes, depending on how much material you have. Message me first with your deadline.
