Claim & entity matrix

Reading a draft for accuracy fails for a boring reason: the work is unstructured. You notice a figure on page two, decide to check it later, and by page four you cannot remember which numbers you already confirmed. The matrix removes that bookkeeping. Every claim becomes a row with an identity, a state and a place to put the evidence, so the next decision is always about one row rather than the whole document.

Sorting is what makes it usable on a long piece. Sort by type to do all the statistics in one pass while the calculator is open, then by status to clear whatever is still unverified. Sort by claim text when a client asks whether a specific figure was checked — it is one lookup instead of a re-read.

Verified means you found evidence and it supports the sentence as written: the row should carry the URL where you found it. Unverified is the honest default and stays that way until you act — a matrix full of unverified rows is a true picture of the work left. Flagged is for the claims that fail: a number nobody can source, a company that does not exist, a link that 404s or points somewhere unrelated.

The source URL is not decoration. A verified status without a source is an opinion, and the certificate will not accept it. Paste the page you checked, even when the same document supplies several rows — future you, or the client's compliance team, needs to re-open the evidence without repeating the search.

Long-form work rarely finishes in one sitting. The draft, the statuses and the source URLs are kept in this browser's local storage as you type, so closing the tab and coming back tomorrow returns you to the same table. Nothing is uploaded, which is also why the tool cannot recover your work on another machine: the record lives on this device until you clear it.
