Frequently Asked Questions

Common questions about Unstale – Refresh Old Posts with AI, Fact-Check & Republish

You pay your AI provider directly, per token. Unstale shows an estimate BEFORE each launch and logs the real cost after. For a 1000-word article at the Balanced level the estimate runs from roughly $0.50 to $1.50 depending on the model you pick. That estimate bounds the worst case (it assumes every web search the level allows is spent), so the cost logged after the run is usually lower. Web search fees are part of the estimate but only appear in the logged cost when your provider reports how many searches it ran. WordPress does not standardise that number, so the logged cost can understate searches on some providers.

No. WordPress calls the provider you connected, directly. The only request to unstale.ai is the public model catalog (no content, no personal data).

None of its own. Since WordPress 7.0, credentials live in Settings > Connectors and are managed by WordPress. Unstale never sees, stores or transmits them. If you used an older version of this plugin, the API keys it had stored are deleted automatically when you update.

Not by default. Every refresh waits in the review queue with a side-by-side diff. You can enable full-auto publishing in the settings if you want it.

No: the bump is skipped automatically when your permalink structure uses the core date tags. To keep dated URLs AND bump dates, switch your structure to the %unstale_year%, %unstale_monthnum% and %unstale_day% tags: they freeze the original date in the URL forever. If you deactivate Unstale later, the plugin automatically restores the core date tags so your site keeps routing (posts whose date was bumped will then use the bumped date in their URL). Deleting the plugin files manually without deactivating skips that safety net: re-save your permalink structure in that case.

Whichever models the provider you connected exposes. Unstale ships model cards for Claude Sonnet 5 (default), GPT-5.6 Terra and Gemini 3.5 Flash, with pricing and ratings to help you choose. GPT-5.6 Terra is still in limited preview: if you pick it, Unstale runs GPT-5.5 instead and states the substitution on the model card and in the job log. The catalog is updated remotely: when a provider ships a new model, it appears in your settings without a plugin update.
