Method and worked example
The preferred method is Intl.Segmenter with sentence granularity. Browsers without that capability use a deterministic local fallback that recognizes common terminal punctuation and paragraph boundaries while protecting several titles, dotted initials, and decimal numbers.
Example
“Hello world! How are you? I am well.” contains three sentence-like segments. A decimal such as 3.14 does not become two sentences in the fallback method.
Limits and interpretation
Automated segmentation can vary around abbreviations, initials, ellipses, headings, quotations, unusual punctuation, and fragments without terminal punctuation. Results describe sentence-like segments rather than claiming perfect grammatical analysis. Input is limited to 5,000,000 characters.
Safe local processing
All submitted content is treated as plain text. The tool uses text nodes and safe DOM APIs for results. It does not render pasted markup, call an AI service, request a remote text-processing API, or store drafts for later use.
