One article on demand,
or the whole archive.
The per-article button sources the page in front of you. The sitewide pass works through your blog highest-search-value first, in background batches that chain until the site is done or the period's allowance is spent. An article whose content hash has not moved since its last pass comes back from cache and costs nothing. It never runs on a schedule; a sitewide pass happens because you pressed the button.
Back every claim with a source Google trusts
One background pass reads every article, matches each factual claim to a verified authority (the FTC, Google and SEC), and queues them for your review. Never a random blog; articles already done are skipped for free.
