Yes, we have one: Link
Unfortunatelly it is available only to premium ChatGPT subscribers, but maybe you’re lucky to be one of them. I absolutely recommend this cutting-edge technology 
Assistant features:
- General information about VCMI project, including FAQ
- Technical support
- Modding features, mod format, mod examples, json code generation
- Some knowledge of OH3 mechanics in general
- Some knowledge of broader Heroes 3 scene (WoG, HoTA etc.)
- Posting issues directly to Github
- Posting complains to our Slack channel. If you find GPT talking bollocks, ask to send feedback directly to us.
I also plan to expand it’s Q/A knowledge base as it shows up. Feel free to add your suggestions.
It’s also valuable to post here any tutorials or other content that the Assistant should know.
