A Reddit user initiates a discussion regarding the practical application of creating a "second brain" using local AI models trained on personal information. The post asks community members to share their actual use cases and the insights derived from having an AI that knows everything about them.
- The author considers inputting a decade's worth of journal entries to extract personal insights.
- The discussion includes inquiries comparing whether fine-tuning or Retrieval-Augmented Generation (RAG) is more suitable for such projects.
