Highlighted text retrieval

When you open a note with highlighted text, the sidebar automatically displays the highlighted text in card format. The following three formats of highlight tags are supported: ==, <mark>, and <span>. Custom formats can also be defined using regular expressions.

Highlighted comments

The highlight comment feature allows you to quickly engage with highlighted text, preventing your ideas from slipping away. Simply click on the Widgets in the editing area or directly click the add comment button on the card to open the input box.

The note comment feature allows you to add your thoughts to the entire document without relying on any highlighted text. Click the add file comment on the right side of the search bar to open the input box at the top of the highlight list.

All comments and highlight data are stored in the .hinote folder in the root directory of your vault, giving you complete control over your data.

Export as image

Export your highlighted text and comments to create beautifully designed knowledge cards for easy sharing.

Export as note

Export all your highlighted text and comments as a new note, displayed in Callout format. Each highlight and comment can be linked back to the source note through block references (Block ID).

Extended features of the main view

Drag the right sidebar window to the main view to unlock more features, such as a list of notes with highlighted text, all highlighted cards, and HiCard.

• Notes List: Displays all notes in the knowledge base that contain highlighted text, with the number of highlights indicated.
• All Highlights: Shows all highlighted cards in the knowledge base, allowing you to focus more on the highlighted content.
• HiCard: Implements the functionality to generate FlashCards from your highlighted text and comments, assisting you in memorizing and learning (Pro feature)

AI Comment

AI can assist you in thinking and add the generated content as a comment below the highlighted text.

First, you need to configure the AI provider, API Key, and model in the plugin's settings menu. Currently supported providers include OpenAI, Gemini, Anthropic, Deepseek, SiliconFlow, and Ollama.

Next, configure your custom Prompt. Here, you can use two fields to obtain the highlighted text and comment content: {{highlight}} and {{comment}}.

Finally, you can use your custom Prompt in the AI button on the highlighted card. Or you can input your custom Prompt in the comment input box and directly click the Tab key to trigger the AI service.
