Three small tools writers and SEOs reach for every day — all on one page, all instant, all private.
Turn a page or post title into a clean, web-safe slug: lowercase, hyphens, no punctuation or accents.
Paste your text, enter a word or phrase, and see how often it appears — as a count and a percentage of the total words.
Replace every occurrence of a word or phrase in your text at once — handy for names, dates, prices and repeated typos.
Words, characters, sentences, paragraphs and the longest word — counted live.
Check text against typical X, Instagram, LinkedIn and meta description limits.
UPPERCASE, lowercase, Title Case, Sentence case, aLtErNaTiNg and reversed text.
Clean repeated lines out of any list in one click.
A slug is the readable part of a web address that comes after the domain, such as “how-to-bake-bread” in example.com/how-to-bake-bread. Good slugs are lowercase, use hyphens instead of spaces, and describe the page in a few words.
It lowercases the text, removes accents from letters, replaces every run of spaces and punctuation with a single hyphen, and trims hyphens from the start and end — the standard format used by WordPress and most other platforms.
Keyword density is how often a word or phrase appears in a text, shown as a percentage of the total words. Writers check it to make sure a page mentions its topic naturally without repeating the same phrase too often.
There is no magic number, and search engines do not reward a specific percentage. As a rough guide, most natural writing lands between about 0.5% and 2%. If your density looks high, vary your wording instead of forcing the phrase in.
Yes. You can search for a single word or a whole phrase, and every exact match in the text will be replaced at once. Tick “Match case” if you only want matches with identical capitalisation.
No. All three tools run entirely in your browser, and nothing you type is sent to a server or stored. The only thing saved on your device is your light or dark theme choice.
