Create a personal ai

Hello, I’m a beginner and I’m looking to create a conversational robot that can respond with all the content I give it, using GPT-3 or another model. I’ve seen that there’s an expensive service called Personal AI that can do this, but is it complicated to set up? Are there any open-source tools that can make fine-tuning and data formatting easier? In general, what would be the recommended approach for someone who is not a coding professional?
