A licence buys you the plugin. Every refresh still runs on your own AI provider account, billed at their price, not ours.
One Balanced-level refresh of an article of about 1,200 words, web research and fact-check included, on your own key. The plugin shows this estimate before a refresh you confirm from the editor, the posts list or Content health.

Unstale is a WordPress plugin that rewrites, fact-checks and republishes stale posts with AI, using your own API key. The free plugin on wordpress.org runs real AI at the Minimal and Balanced levels, and sends batches of up to 50 posts, 20 to a page, from its content health screen. Pro adds the Strong and Maximal levels, scheduled automation, bulk refresh from the Posts list at any level with a 100-post batch, and per-category rules.
Yes. Unstale is bring-your-own-key: use a key from Anthropic, OpenAI or Google. You connect it in WordPress under Settings > Connectors, so WordPress keeps it and the plugin never stores it. Neither your key nor your content reaches our servers, and you pay your provider directly, at cost.
Every rewrite lands in a review queue with a side-by-side diff before anything goes live. You approve or reject each refresh. Republishing keeps your URL, slug and history.
No. Install the plugin, connect an AI provider in WordPress, pick a level. The cost estimate is shown before a refresh you confirm from the editor, the posts list or Content health.
Yes. Plans differ only by the number of sites, and you can switch at any time.
Every plan comes with a 14-day money-back guarantee. If Unstale is not the right fit, contact us within 14 days and we will refund your payment in full. See the refund policy.
