FAQ
What AI models or platforms do you work with?
I work with OpenAI, Anthropic (Claude), and other leading LLM providers, as well as open-source models. I can also fine-tune a model for your specific use case.
Can you integrate AI into my existing application?
Yes. I can connect an AI model or chatbot directly into your existing web or desktop app, working with your current codebase and workflows.
Do I receive the source code?
Yes, full source code is included with every package, so you have complete ownership and can maintain the project going forward.
Which package should I choose?
Basic is great for a standalone AI chatbot. Standard adds AI model integration into your existing app. Premium covers a full custom web/desktop app with model fine-tuning.
What do you need from me to get started?
A brief description of your project, any existing app or codebase you'd like AI added to, and access to the platforms or API keys you plan to use.
