The Best Content Refresh Tools, Sorted by What Each One Actually Does

Content refresh tools update posts that are already live. We checked 21 on their makers' pages on September 23, 2026: ten rewrite an existing post, six rewrite it, show you the change and publish it, and none describes checking each claim a post already makes. Of the eight pages in Google's top results for this search on September 23, 2026 that list tools, all eight name Surfer, Clearscope and MarketMuse, which score a post and stop short of a full rewrite.

Disclosure: this site sells a WordPress plugin that refreshes posts. It runs inside WordPress, so it sits after the table, not in it. No link here earns us anything.

What is the difference between a content refresh tool and a content optimization tool?

A content refresh tool updates a page that is already published: it finds the post, changes it and puts it back online. A content optimization tool scores a text against the pages that rank for its keyword. This page follows the work in seven steps, in the order of the table: find the post, score it, rewrite it, verify its facts, review the change, publish it, measure what happened. Lists for this search mix the two kinds, and the overlap is real: optimization tools cover the score step, and some cover find. The method by hand is in refresh old WordPress posts.

21 content refresh tools, seven steps, checked on the makers' pages

We read each maker's product, pricing and help pages, and its wordpress.org listing when there was one, on September 23, 2026. We did not test any output, open an account or submit a form. Dashword, named by six of the eight lists, did not respond when we checked on September 23, 2026, so it is not in the table. Four of the eight are published by the maker of a tool they rank, and all four rank their own first; this table ranks nothing.

A price in a list has no date. Two of the eight put Surfer's entry plan at $79; Surfer's pricing page lists no $79 plan. Four quote $189 for Clearscope's entry plan; Clearscope's page says $129. Four give MarketMuse a price; MarketMuse's pricing page shows none.

Finding the posts and measuring after: mostly Search Console

To find posts, 14 of the 21 read Search Console data, by API, import or CSV export. The other seven do not: MarketMuse estimates traffic from search volume and position, Optimizely sorts by content age, Omnibound scores pages against a buyer profile, RivalFlow suggests pages without naming its data, and Content Harmony, SEOwind and Semrush's Content Toolkit start from a URL or a text you give them. Free options: Search Console itself; Revive by Animalz, which reads 12 months of GA4 data, asks for an email and changes nothing; Leafpad's free plan, three refreshes a day, which rewrites and publishes. After publishing, four of the 21 describe measuring what changed: ClickFlow, SEOTesting, AirOps and Leafpad, which adds a holdout comparison on its Compound plan. To find stale posts without a tool: find outdated content on your site.

Which tools rewrite the post itself, and show you the change

The three names on every list stop short of a full rewrite. Surfer's Auto-Optimize adds entities, facts and paragraphs to a post opened in its editor. Clearscope's Draft with AI writes a new draft; its blog describes a refresh as edits made by hand. MarketMuse returns briefs and update plans.

ClickFlow syncs its new text to the same post, as a draft. Frase writes targeted fixes, each with a confidence score, and sends the approved fix back to your CMS as a new draft. Semrush's Content Toolkit publishes a new article; its help pages do not say it replaces the original. RivalFlow hands you additions to paste. Reoptimize and Page Refresh AI return a plan your team applies, and Page Refresh AI says it is not an automatic rewriter.

Seven name a screen that compares the old and new versions: Frase, word by word; Semrush and Surfer, side by side; ClickFlow, with Accept Changes or Keep Original; AirOps; Leafpad, with a before and after you can undo; and Perennial. Leafpad and Frase can publish without you, if you choose: Leafpad automatically, Frase for low-risk changes above a confidence bar you set, never a statistic. Maintouch describes automatic updates on its top public plan. Frase is on six of the eight lists, AirOps on two, Slate on one, its maker's own; ClickFlow, Leafpad and Perennial are on none. What to check before approving: the content refresh checklist.

Checking the facts already in the post

Rewriting with fresh search results is not the same as checking what a post already claims. Thirteen of the 21 do something close, each in its own way. Surfer adds facts taken from top search results and AI answers and shows their sources; its pages do not describe auditing the facts already in the post. Frase refreshes a statistic based on the pages that now rank, and a statistic edit always waits for a human. SEOTesting flags claims that need a proof or a source; its pages do not say it finds one. Leafpad checks a post against your company's own information, such as prices, features and policies, and flags what may no longer be accurate. AirOps scores claim support among its automated checks. None of the 21 describes giving each claim already in a post a verdict with a source, so the Verify column holds no Yes.

How a platform writes into WordPress

On the makers' pages, WordPress integration means four different things. Some platforms write to your site from outside, through the WordPress REST API and an Application Password: Slate, AirOps, Leafpad and Perennial document it, Frase publishes through the API with no plugin to install, and ClickFlow and Maintouch do not say how. Three wordpress.org plugins show a score or recommendations in the post editor: Clearscope, Frase and Semrush's SEO Writing Assistant. Two move a post between WordPress and the platform's own editor: Surfer and Semrush's Content Toolkit. Five leave you to paste the result yourself: RivalFlow, Content Harmony, MarketMuse, Reoptimize and Page Refresh AI. None of these plugins rewrites a post on its own inside WordPress.

If your posts live in WordPress

The other family runs inside WordPress. Unstale, the plugin this site sells, is one: it works through the AI provider your site connected in WordPress, with no server of ours in the path. Before rewriting, at every level, it checks the post's main factual claims against the web and shows that check above a side-by-side diff; it publishes to the same post and address. It finds posts by age and by overlap between your own posts, not by traffic, gives no score and measures nothing after: pair it with Search Console for finding and measuring. The plugin is free; Pro is $59, $149 or $299 a year, plus your AI provider's bill. Others like it: WordPress content refresh plugins.

Which content refresh tool for which job

We tested no tool's output, so this is not a ranking: each pick rests on what its maker's pages say.

• Find declining posts with no budget: Search Console, and Revive by Animalz.
• Have a post rewritten, shown to you and published, on one CMS or several: Frase, ClickFlow, Leafpad, whose free plan does it, and AirOps, which shows no public price.
• Get a score while you rewrite by hand: Surfer, Clearscope.
• Hand your writers a plan, not a rewrite: Reoptimize, Page Refresh AI.
• Run several client sites: ClickFlow, if they sit on different CMSs (it publishes to six), or Leafpad's Portfolio plan, for unlimited sites.
• Keep everything inside WordPress: see If your posts live in WordPress.

Questions about content refresh tools

Which products are called Revive, and what does each do?

Four. Revive.so, a WordPress plugin, republishes old posts and, on paid plans, rewrites them with OpenAI; its free wordpress.org version only republishes. RevivePress, formerly WP Auto Republish, resets the publish date without rewriting and was last updated in December 2024. Revive Social shares posts to social networks. Revive by Animalz lists declining posts from GA4 and edits nothing.

Does Google's Refresh Outdated Content tool refresh my page?

No. It lets someone who does not own a page ask Google to update a search result or snippet after the page was removed or changed significantly. It changes Google's result, never the page; an owner asks Google to recrawl instead.

How do I tell if an AI content refresh tool is still maintained?

Its pricing and help pages should load and show dates. For a wordpress.org plugin, check the last update and the warning shown on plugins not tested with the last three major WordPress releases: on September 23, 2026, three of the five platform plugins above carried it, as did RevivePress.
