Free Text & SEO Tools
Working tools for people who work with words: a live word and character counter with reading time, a case converter for every convention from Title Case to snake_case, a line-by-line text diff, a JSON formatter and validator, a URL slug generator, keyword density analysis, readability scoring, a distraction-free notepad with dictation, a teleprompter and a bionic reader.
Each tool is keyboard-friendly, handles large pastes without choking, and updates live as you type. Writers use the counter and readability scores to hit editorial limits, developers use the diff and JSON tools during code review, and SEO folk use the density analyzer and slug generator to tune pages — all without pasting sensitive drafts into a site that stores them.
