Everything here takes plain text in and gives cleaner, better-organised text back: counters that report words, characters and reading level as you type; cleaners that strip duplicate lines, extra spaces or unwanted symbols; and transformers for case, order and layout. Paste, adjust, copy — every tool runs locally, so even large documents are processed instantly and nothing you paste leaves your device.
