The Simple Prompt plugin allows users to generate or rewrite content in Obsidian using Large Language Models (LLMs) like OpenAI and Ollama. It offers an easy-to-use interface for generating content at the cursor, rewriting selected text, or replacing the entire document based on a user-provided prompt. Additionally, users can generate content from YouTube videos using captions, and customize prompt templates for personalized content creation. The plugin supports features like recent prompts, the option to choose from different LLM providers, and streaming responses for generation. Future features include expanded LLM support, image generation, vault document indexing, and enhanced encryption for API keys.
