Find Outdated Article Stats: DuckDuckGo + OpenRouter (n8n)

Find Outdated Article Stats with DuckDuckGo + OpenRouter (n8n)

Paste an article URL into this n8n workflow and instantly see where its quoted figures are outdated—side by side with later, on-the-web numbers quoted word-for-word from their sources. No guessing, no API keys for search pages—just a clear review table so you can verify updates quickly.

What this workflow does

• Collect inputs via a form: enter the article’s address and optionally a region.
• Read the article with DuckDuckGo: the DuckDuckGo node fetches and extracts the content.
• Extract dated figures: the model lists up to five figures that include the year they refer to, then code keeps only cases where the sentence (with the value and year) is truly present in the article—dropping forecasts.
• Search for later replacements: for each extracted figure, the workflow performs one DuckDuckGo search per figure, with a short wait between searches.
• Verify later figures with citations: the model proposes later numbers; code keeps a candidate only if its quote appears on the source page, the value and a later year are close together, and it’s not a forecast (and flags cases with a different unit).
• Show a review table: the form displays the original dated sentence next to the later quoted sentence, including the later source. Every run ending path is surfaced with a page.

Use cases

• Update SaaS documentation or marketing pages that rely on public statistics.
• Perform content QA for blogs and research summaries by validating whether numbers still hold.
• Help automation engineers build “living” knowledge bases with verified, source-backed replacements.
