The Title Generator plugin streamlines the process of creating meaningful titles for your Obsidian notes using OpenAI's GPT-3.5. It analyzes the content of one or multiple notes and generates titles automatically, which are then applied directly to the notes. Users can generate titles through the command palette, editor menu, or file menu, with options for single or batch processing. The plugin also allows customization, including a setting to enforce lowercase titles. It is ideal for users who want to organize their notes efficiently without spending time crafting titles manually.
