Tools in this category
Text Diff
Compare two blocks of text online and highlight added, removed and unchanged lines, so only the lines that changed are marked. Runs in your browser.
Word Counter
Count Chinese characters and English words separately, alongside characters, lines, real UTF-8 bytes and reading time. Runs in your browser.
Text Cleaner
Clean up a column pasted out of a log or spreadsheet: deduplicate, sort, drop blank lines, trim whitespace and strip line numbers, all in your browser.
Case Converter
Convert identifiers between eight naming styles. Words are split correctly first, so acronyms such as HTTPServer come out right, all in your browser.
Chinese Converter
Convert Chinese between simplified and traditional characters, leaning on common words first and the most usual form for the rest, all in your browser.
Regex Tester
Test a regular expression with live highlighting, capture groups and a replace preview, guarded against catastrophic backtracking. Runs in your browser.
Markdown Preview
Write Markdown on the left and see it rendered on the right, with pasted HTML shown as text and images never fetched. Runs entirely in your browser.
