The AI for Templater plugin enhances Obsidian's Templater by integrating it with large language models like OpenAI's ChatGPT. Users can easily interact with these models by sending questions or commands directly within their notes. This plugin enables functionalities like asking questions or generating content using AI, improving workflow and automating tasks within Obsidian. With support for OpenAI's API, it requires an API key and allows for customization to use local LLMs as well. It's a useful tool for those looking to integrate AI-powered assistance into their note-taking and content creation processes.
