Bulk accepts 5,000 lines including blank lines, trims row edges, skips blank lines and preserves order with LF output. Results appear only when the whole batch succeeds. Turn bulk off for the original full output. Title capitalizes only the first character of whitespace-separated words; Sentence only the first character of each line, lowercasing the rest. Opening punctuation is not skipped. Inner punctuation and whitespace stay. CompareTwoTexts Modes checked: 2026-10-28. Unicode casing / abbreviation handling is heuristic, not transliteration.

Each field: 1 MiB UTF-8 (SQL: 100,000 characters); output: 2 MiB. Loading stops after 15 seconds; processing after 2 seconds. Local processing, without uploads or storage.

Enter input or load a sample, then run.

How to use this tool

Paste an identifier or prose to compare variants, or explicitly convert a list line by line in a selected case. Acronym boundaries are estimated.

When not to use it

Word splitting and sentence capitalization are heuristics, not linguistic editing or identifier validation. Review acronyms and language-specific casing.
