Paste a quote and the source text it came from. This checks, word for word, whether they still match, and shows you exactly where they drifted. Nothing is uploaded. It all runs on your machine.
You just ran it on one quote. Cite Engine runs it automatically on every quote in your Obsidian notes, the moment a source changes. The link stays green, but it flags the quote that quietly stopped matching.
It compares your quote against the source as plain text. If your quote appears in the source word for word, it matches. If it does not, the tool finds the closest passage in the source and highlights what changed: struck red for the words in your quote that no longer appear, green for the words the source says now. No AI, nothing is invented, your text never leaves the page.
Because you edited the source after quoting it. You tightened a sentence, fixed a typo, reworded a passage. The quote you pasted earlier is a frozen copy that never updates. More on quotes going out of sync →
