Frequently Asked Questions
Everything you need to know about using this application.
How do I create a markdown footnote using this tool?
To create a footnote, simply type your content and place the cursor where you want the citation to appear. Use the 'Insert Footnote' button to generate the standard Markdown syntax: a caret symbol followed by a bracketed identifier, such as [^1]. The tool automatically handles the association between your inline citation marker and the corresponding footer definition. When you add a new footnote, the application appends the necessary reference block at the bottom of your text, ensuring that your document maintains valid syntax throughout the editing process.
Is my data private and secure when using this tool?
Yes, your data is completely private because this application runs entirely within your browser. We do not use servers, databases, or cookies to process your input; all operations happen locally on your device in real-time. Furthermore, because the tool is designed to work in a sandboxed environment, it does not use local storage or persistent memory. When you refresh the page or close your browser, all input data is cleared immediately. Your work is only as permanent as your decision to copy it to your clipboard.
What happens if I make a mistake while formatting citations?
The tool features a real-time validation engine that monitors your syntax for common errors, such as unmatched markers or missing reference definitions. If a citation is orphaned (missing its corresponding footer), the interface will highlight the issue with a soft, unobtrusive warning indicator. This immediate feedback loop allows you to fix structural errors before you export your final text. You can easily remove or reorder citations, and the application will dynamically adjust the reference list to ensure your document structure remains intact and error-free.
Are there limits on the number of citations I can add?
There are no arbitrary limits on the number of citations or footnotes you can add to your document. The application is designed to be lightweight and efficient, allowing you to manage long-form academic or technical documents with hundreds of references without experiencing performance degradation. However, since the app runs in the browser, extremely large documents might eventually consume significant memory. For the best user experience, we recommend using this tool for individual chapters or sections of your writing project, and copying the final output into your preferred document editor.
