Count words and characters, estimate reading time, change case, clean spaces, and find/replace — entirely offline in your browser.
Reading time is derived from the live word count using a simple on-page estimate — useful for drafts, not a lab-grade reading study.
The controls provide plain find/replace with an optional case-sensitive checkbox. There is no separate regex mode in the UI.
No. Analysis and transforms run locally. Clearing the page or using a private window discards the workspace contents.
