The Substitutions plugin enhances your Obsidian workflow by automatically replacing specified text fragments with symbols or alternative text as you type. Users can configure, enable, or disable these substitutions via an intuitive settings pane, providing a seamless way to streamline repetitive text input or improve formatting. The plugin is ideal for those who frequently use symbols, custom abbreviations, or specialized text formatting in their notes.

The Replace Pencil plugin allows dynamic text replacement within code blocks by using placeholders. Users can define a custom prefix in the settings and wrap any text they want to replace in the chosen placeholder format, such as angle brackets. In Reading Mode, an input field and a clear button appear beside the code block, enabling on-the-fly updates. A copy button simplifies exporting the modified content to the clipboard, while a sidebar eraser button resets all changes instantly.

The Replace All plugin enhances text replacement capabilities within Obsidian by adding a powerful find-and-replace-all functionality. Users can quickly search for specific terms within their notes and replace them in bulk, streamlining content editing and management. The plugin integrates seamlessly into Obsidian's core file functionality, making it intuitive to use without disrupting the workflow. Additionally, it provides an undo feature to revert bulk replacements, ensuring safe content modifications.

The Auto Replacer plugin automates text replacements in your notes using custom rules built with regex and JavaScript. It lets you define patterns and transform functions through an intuitive UI, applying changes live as you type. Whether it's formatting measurements, highlighting keywords, or dynamically inserting note titles, this plugin gives you full control over text automation without manual edits. Advanced users can reference editor and file objects in their scripts for context-aware replacements, but care is needed since running arbitrary code carries risks.
