How to use Filter Text Sentences
- 1. Paste the passage you want to narrow down. Enter a paragraph or document made of multiple sentences, such as a transcript or article where only certain sentences are relevant to your current task.
- 2. Set the Pattern. Type the text or regular expression each sentence must contain to be kept, such as a topic keyword or a specific phrase you're scanning for.
- 3. Adjust the regex, case sensitivity, and Invert options. Turn on Use a regular expression for pattern-based matching, Case sensitive for exact capitalization, and Invert to keep the sentences that don't match instead of the ones that do.
- 4. Copy the filtered sentences. Copy the surviving sentences into your summary, report, or wherever the narrowed passage is needed.
When to use Filter Text Sentences
Filter Text Sentences keeps only the sentences that match a pattern, letting you isolate specific statements from a longer passage without reading through it line by line. Use Filter Text Sentences to pull relevant statements out of a transcript, article, or long-form document around a particular topic.
- Extracting statements about a topic from a transcript. A meeting transcript covers multiple topics and you only need the sentences discussing a specific project. Filtering for that project's name pulls out just those statements.
- Isolating quoted claims from a long article. An article mixes narrative text with direct quotes, and you want to review only the sentences that reference a source or contain quotation marks using a pattern.
- Removing off-topic sentences before a summary. A document has tangential sentences that shouldn't factor into a summary you're preparing. Using Invert with the tangent's keyword strips them out, leaving only relevant content.
- Finding sentences that reference a specific date or figure. A report needs every sentence mentioning a particular financial figure pulled out for a quick audit, using a regular expression pattern to match different number formats.
Examples

Input
It rained. We played. Rain fell again.

About the Filter Text Sentences tool
Filter Text Sentences is a free online tool that works entirely inside your web browser. Keep only the sentences that match a pattern or regular expression. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 211 Text utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 4 settings, including Pattern, Use a regular expression, Case sensitive and Invert (keep sentences that don't match), 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.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
