Can I highlight sentences by number or keyword?

The tool allows you to specify which sentences to highlight, but the exact method depends on the rule options provided in the interface; you can typically target sentences by their position or content patterns.

Does the tool preserve the original formatting of my text?

The output highlights the selected sentences while keeping the surrounding text intact, but complex formatting like bullet points or special characters may not be fully maintained.

Is there a limit to how much text I can process at once?

The material does not specify a character limit, but very large documents may take longer to process or behave unexpectedly due to the browser-based nature of the utility.

Can I use this tool to extract or list the highlighted sentences separately?

No, the tool is designed to produce a visually marked version of the text; it does not generate a separate list or export of just the highlighted sentences.

What Highlight Sentences does

Highlight Sentences in Text is a browser-based utility for marking specific sentences within a block of prose. Users paste their text into the input area, define which sentences to emphasize, and receive a version where the chosen sentences are visually highlighted, making them stand out against the surrounding content. The tool processes the continuous text and separates it into discrete, marked units, eliminating the need for manual counting or segmentation. It is designed for anyone who needs to isolate key statements quickly, including educators reviewing lesson material, writers editing drafts, and professionals analyzing reports or legal documents. The output presents the text with the selected sentences emphasized, allowing for easier scanning and focus on particular ideas or claims without altering the original wording.
