The Smart Text Mover plugin helps organize text and external links in Obsidian files by suggesting headings where the content can be moved. It supports three modes: a simple position-based list of target sections, LLM-powered suggestions for files with minimal data, and a Naive Bayes classifier that improves with usage by analyzing word distributions under headings. Users can easily relocate selected lines of text by choosing from ranked suggestions based on proximity. The plugin is particularly useful for tasks like categorizing bookmarks and works well alongside tools like the URL Namer plugin.
