Editing tools catch what tired eyes miss: a doubled word, a sentence that lost its verb, a paragraph that says the same thing twice. For a blogger who writes and publishes alone, with no editor between the draft and the reader, that second pair of eyes is often worth more than any drafting tool.
The tools here split into two kinds. Grammar and style checkers underline errors and suggest corrections as you write, many of them through a browser extension that works inside the WordPress editor or a newsletter composer. Readability tools look at the shape of your writing instead, flagging long sentences, passive voice and words with simpler alternatives, which matters when most readers open your post on a phone.
Rewriting tools sit in between. You select a clumsy sentence and get alternatives that are shorter, more formal or more casual. They are good for unsticking a paragraph you have rewritten five times, less good for a whole post, where they can sand off the quirks that make your writing yours.
Accept suggestions one at a time. Style advice from these tools is general, and a blog voice often breaks general rules on purpose: a one-word sentence, a casual aside, a deliberate repetition. Fix real errors, consider the clarity suggestions, and ignore anything that makes you sound like a manual.
What a featured listing costs ยท from $99 a month
Checks grammar, clarity and tone as you write, in the browser, in many blog editors and in its own apps.
Grammar and style checker with detailed reports on repetition, sentence length and readability for long posts.
Highlights long sentences, passive voice and complex words so posts are easier to read on a phone.
Grammar and style checker that works in many languages, useful for bloggers who publish in more than one.
Paraphrasing tool with grammar checking and summaries, often used to rework clunky sentences in a draft.
Suggests alternative ways to phrase a sentence, shorter, more casual or more formal, as you edit.
If you publish in more than one language, check which languages a tool supports before you rely on it. Free plans are common for the basic checks, with paid tiers adding rewrites and deeper style reports.
A simple routine works for most bloggers. Run the grammar check first and fix the errors it finds. Then read the post on your phone, the way most readers will see it, and break up any paragraph that fills the screen. Finally, look at the readability highlights only for the sections that felt slow. Three short passes catch more than one long one, and you keep control of the voice at every step.
If you write in more than one browser or on more than one device, check where your settings and personal dictionary live. Adding the names, brands and terms you use often stops the same false alarms from appearing on every post.
Paste-in editors also work when a tool has no extension for your setup: copy the post in, fix what it flags, and paste it back before publishing.
Several do through a browser extension that checks text in web editors, including the WordPress block editor. Tool pages here show a browser extension where we could confirm one.
Only if you accept every suggestion. Review them one by one, fix genuine errors, and skip style changes that don't sound like you.
It flags long sentences, passive voice and complex words, which make posts harder to read on a phone. Treat the highlights as prompts, not rules.
For catching spelling and grammar errors, free plans are often enough. Paid plans mainly add sentence rewrites, tone suggestions and longer style reports.
