How to use Highlight Sentences in Text
- 1. Paste the text to scan. Paste a paragraph or longer passage into the input pane, made up of multiple sentences you want checked for a specific topic.
- 2. Enter the term and case rule. Type the word or phrase to look for into Contains, and toggle Case sensitive to control whether matching respects letter case in the search.
- 3. Review the highlighted sentences. Review the rendered passage where every whole sentence containing your term is visually highlighted, letting you scan just the relevant sentences at a glance.
When to use Highlight Sentences in Text
Highlight Sentences in Text marks whole sentences that contain a word or phrase, rather than just the matching word itself. Use Highlight Sentences in Text when you need the full context of a sentence flagged, not just a single term underlined.
- Reviewing every sentence discussing a topic. A long report touches on a topic like budget in several places, and highlighting every sentence that mentions it lets a reader jump straight to the relevant context.
- Fact-checking claims about a specific subject. An editor needs to verify every sentence in an article that references a particular statistic or claim, and highlighting them by keyword surfaces each one for review.
- Extracting relevant context from meeting notes. Meeting notes mention a project name scattered across a long document, and highlighting the sentences that reference it groups the relevant context visually for a quick recap.
Examples

About the Highlight Sentences in Text tool
Highlight Sentences in Text runs as plain JavaScript in your browser tab, with no server behind it. Highlight whole sentences that contain a word or phrase. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Text Tools section, 211 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including Contains and Case sensitive, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.

Does Highlight Sentences in Text cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
