Blog Factcheck

Runs through your blog post and checks whether the statistics you cited actually appear in the sources you linked. It extracts every claim with a number or percentage, fetches the cited URLs, and scores how well the source backs up what you wrote (1.0 for exact match, 0.8 for close paraphrase, 0.0 if it's not there). Flags unsourced claims as unverified and suggests search queries to find sources. The workflow is straightforward: read the file, extract claims with their URLs, fetch each source page, check if the numbers match. Good for cleaning up drafts before publication or auditing older posts where links might have rotted. Processes up to 10 URLs per run to avoid hammering servers.
