txtkit とは？

txtkit puts 17 text tools into one clean workspace — no jumping between sites, no account required. There are three tabs: Writing (word counter, readability, keyword density, character limits), Editing (case converter, text cleaner, deduplicator), and Developer (code case conversion, line counter, HTML stripper). Your text stays put as you switch between tools, and everything runs in the browser — nothing hits a server.
