Ears catch what eyes miss. Kaizen Speech Studio reads your edited text aloud in 700+ natural AI voices, with MP3/WAV export — fully offline on Windows.
Prefer to listen in the browser first? Try the free Text to Speech tool.
The same find & replace you know from Word or Notepad — but in your browser, for any pasted text, with a live match counter so you see exactly how many occurrences you're about to change. Leave Replace empty to simply delete every match. Nothing is uploaded.
(\d+)-(\d+), replace $2-$1 to swap number pairs. Invalid patterns flag an error instead of running.| Job | Find (regex) | Replace |
|---|---|---|
| Collapse repeated spaces | [ ]{2,} | (one space) |
| Strip all digits | \d+ | (empty) |
| Swap "Last, First" names | (\w+), (\w+) | $2 $1 |
| Remove trailing spaces per line | [ \t]+$ | (empty) |
For line-break cleanup specifically, Remove Line Breaks is one click; recase results with the Case Converter.
Extracting text from scans before you clean it? Kaizen OCR & PDF pulls accurate text from images and PDFs in batch. And when the final copy is ready, Kaizen Speech Studio narrates it in 700+ AI voices — both offline Windows apps.
Paste your text, enter the word in Find and its replacement in Replace, then click Replace all. The match counter shows how many occurrences exist before you commit.
It only matches the term when it stands alone — replacing 'cat' won't touch 'catalog' or 'concatenate'. Word boundaries are letters/digits/underscore edges.
Yes — enable Regex mode and Find is treated as a JavaScript regular expression, with $1, $2 capture-group references available in the Replace field. Invalid patterns show an error instead of running.
No — matching and replacing run entirely in your browser. Nothing you paste leaves your device.
