The Reading Comments plugin enhances the note-taking experience in Obsidian by allowing users to create, manage, and interact with inline comments in markdown notes. Comments can be tagged hierarchically and grouped for better organization. Users can toggle between block and inline comments, search through them, and navigate to specific comments easily. The plugin also supports extracting the original note with links to the comments for better integration with the vault. Additional features include hiding comments until hovered, color customization, and light/dark theme compatibility.

The Better Comment Toggle plugin improves comment management in Obsidian, offering enhanced functionality for toggling comments line-by-line or across selected ranges. It supports customizable start and end tokens, making it adaptable for various syntaxes, including code and math blocks. The plugin maintains proper indentation and allows users to style commented lines for better readability. Fully WYSIWYG, the plugin ensures that comments are visible exactly as they appear in the notes, without hidden metadata. Users can define their own comment styles, such as HTML or Obsidian-specific syntax, to suit their workflow.

The HiNote plugin brings a powerful highlighting and annotation system to Obsidian, allowing users to extract, comment on, and interact with text directly within their notes. Highlighted text is automatically collected and displayed as cards in a sidebar, where users can add manual or AI-generated comments. Highlights can be exported as shareable images or converted into structured notes with links back to the original content. The plugin also offers an expanded main view to explore highlights across the vault, initiate AI conversations, and generate flashcards for study.

The Note Annotations plugin enhances the reading experience in Obsidian by providing features for highlighting text and adding inline comments. Users can highlight selected text in live preview mode and attach margin notes for better organization and review. The plugin supports multicolor highlights by using color tags, allowing for categorization of annotations. It offers an intuitive way to engage with notes actively, making it easier to revisit important content. The plugin settings allow customization of highlight colors.
