The NoteSmith plugin streamlines the process of refining unstructured notes by sending their content to an OpenAI-compatible model for cleanup. It corrects grammar, punctuation, and structure while improving Markdown formatting and applying proper heading hierarchy. Lists can be converted into actionable tasks, and optional tag annotations like #todo or #idea can be inserted automatically. Users can further tailor results by adding their own prompt instructions in the settings. The plugin integrates with the command palette and context menu, making it quick to run the refine action on any note. Security is handled locally, with the API key stored only on your device and requests sent exclusively to the configured endpoint.
