Sentence Length Analyzer

Inspect sentence or line candidates with language-aware segmentation, word/scalar/grapheme lengths, source offsets and complete JSON review reports.

Choose your path

Built around the job you need to finish

Inspect locale-sensitive sentence candidates or explicit line records, compare word/scalar/grapheme lengths and trace complete segments to original UTF-16 ranges.

Multilingual editor

Review Chinese and Latin boundaries without ASCII-only splitting.

Choose zh or en, compare CJK punctuation, decimals and actual candidate text.

Can correct editorial assumptions instead of treating segmentation as grammar proof.

Accessibility-minded writer

Find segments worth reviewing without a universal length grade.

Choose words/scalars/graphemes, set a review threshold and compare complete candidates.

Threshold markers prompt contextual review, not an accessibility verdict.

Mobile transcript reviewer

Trace long or punctuation-free records without losing text.

Switch sentence/line boundaries, inspect UTF-16 ranges, sort longest first and export 220 candidates.

Original segment numbers and complete text survive sorting and preview limits.

Analysis

Reference & details

How it works

Candidate boundaries

Sentence mode uses this runtime’s Intl.Segmenter for a supported language tag. Line mode uses explicit Unicode line records. Ambiguous text can differ across runtime dictionaries.

Lengths and provenance

Count word-like segments, scalars or graphemes after excluding boundary Unicode whitespace. Report original source ranges and complete untrimmed segment text separately.

Review, not grading

Mean, median, minimum and maximum describe selected lengths. A strict greater-than threshold is your review marker, not a universal readability or accessibility standard.

Common Mistakes to Avoid

Treating a short segment as clear or accessible

Read the actual content and check reader needs; length alone proves neither.

Assuming every line is a sentence

Line mode deliberately treats records as candidates, including punctuation-free fragments.

FAQ

No. It provides segmentation candidates for you to inspect in context. Abbreviations, transcripts and mixed scripts can be ambiguous.

Choose a supported language tag such as zh and inspect each candidate. Runtime segmentation data can affect word and sentence boundaries.

Word-like segments, Unicode scalars and grapheme clusters measure different things. Choose the basis suited to your review.

No. It is a user-selected marker; only lengths strictly above it are flagged. Context and affected-reader feedback remain necessary.

The report includes full candidate text and source ranges for all result rows. Keep the original source too, especially whitespace-only records excluded from analysis.
