19 free tools for editing, formatting, counting, and cleaning up text — all running locally in your browser.
Writing rarely happens in one clean pass — text gets pasted between apps, copied out of PDFs with broken spacing, drafted with inconsistent capitalization, or checked against a word limit at the last minute. This collection brings together the small, repetitive text tasks that come up constantly for writers, students, developers, and editors: counting words and characters, converting between letter cases, comparing two versions of a document, cleaning up messy whitespace, and more.
Every tool here works the same way — paste your text in, get an instant result, nothing leaves your browser. There's no daily limit and no account needed, so these are built to be reached for quickly, used, and closed again.
