Writing, reading and fixing text

The most-used tool in this category is the Text to Speech Reader: paste in an article, an essay or your own draft and hear it read aloud in your browser’s own voices, with speed and pitch controls and sentence highlighting. Writers use it to proofread — ears catch the typos eyes skip — students use it to revise, and it doubles as a genuinely practical accessibility tool for anyone who finds long reading hard on the eyes. Its mirror image is the Voice Dictation tool, which turns speech back into text.

The rest of the category is about text that arrives broken or needs reshaping: the Mojibake Fixer rescues garbled text from mis-encoded CSVs and emails (the "Café" problem), PasteFix repairs the mangled line breaks you get when copying out of a PDF, and the Word Counter and Subtitle Editor handle counting and captioning. Everything runs in your browser — your text is never uploaded.

Guides from the blog

Every text limit you will ever hit — a tweet, an SMS, a meta description — is a character count in disguise. Our guide to counting characters explains how Twitter, SMS and search snippets each count differently, and how to check your text before a platform truncates it for you.
