Scan every post on your site for grammar, spelling, and style errors — then fix them in one click
SEOMedic Simple Grammar Checker is a free WordPress plugin that turns proofreading into an ongoing SEO habit rather than a one-time chore. No account, no API key, no subscription.
Old content is quietly costing you rankings and trust
Typos and clumsy grammar quietly erode reader trust and conversions.
Editing posts one at a time is slow — nobody audits an entire archive manually.
Old content silently decays in the rankings, and you never get around to refreshing it.
Other tools need accounts, subscriptions, or API keys. This is free and works out of the box.
Proofreading that actually gets done
The plugin runs inside wp-admin and reads post content straight from the database, so it works with both the Classic and Block (Gutenberg) editors — regardless of how a post was written. Text is sent to the free public LanguageTool API to get suggestions. No account, no API key, no paid plan required.
Grammar cleanup is content maintenance — and Google rewards it
Most sites publish a post once and never touch it again. But search engines favor content that is actively maintained. When you revisit an older post and genuinely improve it, you refresh its "last updated" signals — one of the freshness factors Google uses to rank content.
The plugin reframes grammar cleanup as legitimate content maintenance that keeps older pages competitive — a high-leverage SEO task most site owners skip because it is tedious. This tool makes it fast and systematic.
Everything you need to clean an entire archive
A complete proofreading toolkit built for WordPress — designed to make content maintenance fast, systematic, and safe.
Whole-site scan
Check any number of posts and pages in one session. Long posts are automatically split into chunks so nothing is missed.
One-click fixes
Each error shows up to five suggestions. Click to apply and the post updates instantly — no manual editing required.
Proprietary Post Score
Every scanned post gets a color-coded 0–100 score blending grammar, readability, and sentence length. Spot your weakest pages, then watch the score climb.
Custom dictionary
Add brand and product names so they are never flagged again. Recognizes proper names — including hyphenated and accented ones.
Synonym-aware Find Posts
Search your content by word, synonym, or anchor text. Great for internal-linking audits and editorial cleanup.
Disable error types
Switch off whole categories — repetitions, style, and more — site-wide, with a plain-English glossary explaining each.
60+ languages
Checks any language LanguageTool supports, auto-detected or chosen manually.
Offset-accurate replacements
Fixes map back to the exact bytes in the original HTML, so tables, blockquotes, and formatted text are never corrupted.
Built for site owners who care about credibility
Bloggers, content marketers, agencies, and site owners with a back catalog of older posts who care about SEO and credibility — but do not want to open and re-edit each post by hand.
Free, private, and safe by design
