The Prompt ChatGPT plugin enhances your Obsidian workflow by automating the process of sending customized prompts to ChatGPT. Users can create templates with placeholders like {{title}} and {{context}} that are dynamically filled when opening or creating a note. Once set up, the plugin sends these prompts to ChatGPT, generating responses based on your note’s content. It supports direct communication with ChatGPT via a chatbox, and offers features like conversation retention, which allows you to store recent responses. Additionally, it customizes ChatGPT's behavior for a personalized experience, making it a seamless tool for users looking to integrate AI-driven insights into their notes.
