Financial journalists and equity analysts publish earnings stories on deadline, and one wrong figure means a public correction. AI now drafts more of that copy, which makes numbers cheap to write and costly to check. NoCap checks every financial number in a draft against SEC filings before it runs, and shows the filing behind each.

Paste a draft about any S&P 500 company and press Check. Each figure comes back ✓ verified, ✗ wrong, ◷ not public yet or ? unverifiable. Click a figure for its receipt: the filed value, the reason, and the 8-K, 10-Q or 10-K with its accession number and EDGAR acceptance time. Fix with receipts proposes corrected numbers and rechecks the whole draft. Check a slide and Ask apply the same verifier to earnings slides and questions.

Meta models read; code decides. Muse Spark turns prose, tables and charts into typed claims, and deterministic code verifies each one against filed data. A number code can't confirm gets ?, never a guess.

Proof, from frozen tests run once:
- One-shot test of the November 2 release (1,000 items, 400 S&P 500 companies): 306 of 360 planted errors caught, none marked verified; a ✓ was right 736 of 738 times.
- Held-out seeded errors: 44 of 48 caught; the 4 misses came back ?, never ✓.
- Trap drafts written by Muse Wonder: 20 of 20 planted errors caught.

Free, no sign-up, through November 17; built during the hackathon.
