Text Tools

Live word, character (with/without spaces), sentence and paragraph counts, plus estimated reading and speaking time and a keyword-density breakdown. Runs entirely in your browser.

Convert HTML to clean, readable plain text — tags, scripts and styles stripped, entities decoded, block elements become line breaks. Runs entirely in your browser.

Instantly convert text between 11 casing conventions — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, alternating and inverse. Smart Title Case correctly handles minor words.

Side-by-side or unified diff of two text inputs at line or word granularity, powered by a Myers-style diff algorithm. Additions, removals and changes are highlighted with +/− markers and strikethrough — never by color alone.

Search a pasted document for a term or pattern and replace all or the next match — with case-sensitive, whole-word and regex modes. Capture groups ($1) work in regex replacements, and the match count updates live.

Remove exact-duplicate lines keeping the first occurrence — with case-sensitive/insensitive comparison, whitespace trimming, blank-line filtering and optional sorting. See exactly which lines were removed.

Count total, non-empty and blank lines, see your longest line, and add sequential line numbers to pasted text.

Instantly convert text between 11 casing conventions — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, alternating and inverse. Smart Title Case correctly handles minor words.

Remove whitespace and newlines from pasted text — trim every line, collapse multiple spaces into one, or remove all whitespace and line breaks entirely.

Sort pasted lines alphabetically (A–Z / Z–A), numerically, by length, in natural order or randomly — with case-sensitivity and optional duplicate removal in the same pass.

Reverse text instantly — the whole string, the word order, each word's letters, or the line order. Live result with copy/download.

Parse CommonMark (plus tables and strikethrough) into standards-compliant HTML with a live preview, powered by the `marked` parser. Sanitization of embedded raw HTML is on by default.

Convert HTML to clean, readable plain text — tags, scripts and styles stripped, entities decoded, block elements become line breaks. Runs entirely in your browser.

One unified tool for Base64 (UTF-8 safe), URL/percent encoding and HTML entity encoding — with an encode/decode toggle per scheme and clear inline errors for malformed input.

Generate classic Lorem Ipsum placeholder text by word, sentence or paragraph count — with the traditional 'Lorem ipsum dolor sit amet…' opening (toggleable), reproducible seeded output, and copy/download.

Generate strong random passwords with configurable length and character-set rules, using cryptographically secure randomness. Copy one or download the batch.

Convert titles or any text into lowercase, URL-safe slugs — transliterating accented characters (café → cafe), stripping punctuation, with configurable separator and word-boundary max-length truncation.

Write a regex with flags and see every match, position, and capture group highlighted — perfect for debugging patterns before using them in code.

Turn any text into spoken audio with the Web Speech API — pick a voice and speed, play or stop, with nothing recorded or uploaded.

Speak and watch your words transcribed in real time, in 12+ languages, using your browser's built-in speech recognition — no uploads.

Condense articles and documents into a target number of sentences using frequency-based extraction — fully offline, no AI API calls.

Diff two versions of text with word-, line-, or character-level granularity — additions green, removals red, ready to copy the result.

Wrap long text to a chosen column width (keeping paragraphs intact) or unwrap hard-wrapped text back into flowing paragraphs.

Turn CSV into a clean Markdown table, an ASCII box, or plain aligned columns — perfect for docs, READMEs, and chat messages.

Scan any text for acronyms (2+ uppercase letters) with the sentence context around each one — great for glossaries and documentation.

Score any text with Flesch ease and grade-level formulas — plus average words per sentence and syllables.

Split lines on a delimiter (comma, pipe, tab…) into tab-separated columns, or merge tab-separated columns back into delimited lines.
