About TextKit Pro
TextKit Pro bundles four everyday text utilities into a single page: a word counter with live stats and keyword density analysis, a case converter covering nine common formats (including camelCase and snake_case for developers), a Lorem Ipsum generator for design mockups, and a text diff checker that highlights line-by-line changes between two versions.
Everything runs client-side in your browser — nothing you type or paste is ever uploaded to a server, so there's no wait and nothing to worry about privacy-wise.
