Diligence tool
Did you get the numbers right before you hit publish?
Financial newsletters, blog posts, and threads cite EPS, revenue, and market cap constantly — and it's easy to misremember a figure or copy an old one. NumberCheck reads your draft, finds every $TICKER mention, and checks nearby numbers against what that company actually filed with the SEC. Free, no account, nothing saved.
Free, no account. Compares against SEC EDGAR's most recent 10-K XBRL figures — quarterly numbers or analyst estimates will look like mismatches even when they're not. Read the underlying filing before correcting anything.
Frequently asked
How is this different from an AI fact-checker like a grammar or plagiarism tool?
General AI fact-checkers usually run your claim past another language model and ask if it sounds plausible — useful, but it isn't a primary source. NumberCheck doesn't guess: it pulls the actual number your company filed with the SEC (XBRL data from its most recent 10-K, sourced live from data.sec.gov) and compares your stated figure to it directly.
What claims does it check?
EPS, book value per share, revenue, market cap, total assets, and total liabilities — mentioned near a $CASHTAG-style ticker (e.g. "$AAPL revenue of $95 billion"). It looks in a window of text around each ticker mention so multiple companies in one draft don't get crossed up.
Why did it flag something I know is correct?
It compares against the most recent annual 10-K figure. If you're citing a more recent quarter, a non-GAAP adjusted number, or a forward estimate, it will look like a mismatch even though you're right — that's a limitation of comparing to a single filed baseline, not a claim that you're wrong. Always check the note before correcting anything.
Does it use an AI model to read my draft?
No. Ticker and number extraction is pattern-based (regex), not a language model — deliberately, so results are deterministic and reproducible instead of an LLM's best guess at what a number means.
Is this investment advice?
No. It's a numeric-accuracy check against public SEC filings, not a recommendation to buy, sell, or trust any analysis. Always verify against the primary filing before publishing a correction.
Is there a paid tier?
Not yet — this is a free tool. An API for automated pre-publish checks (e.g. wired into a CMS or Zapier flow) is next if there's real usage.
