Reconciles a well's data across every source — well export, report PDFs, Pason CSV / survey, and the stick diagram — against the QC checklist. Confirms TD/TVD, auto-writes the well notes, charts the trends, flags what doesn't line up, and builds a clean recap. Drop your files in → Run QC → Generate recap. Everything runs on this device.

Extra field notesPaste sectional detail a field rep typed (or a full UniqEnergy report dump). CrossCheck dissects it the same way it reads a report — pulling the key trips, program changes and additions into the right section, not copy-pasting every line. No length limit; the box grows as you type.
Reads everything on this device — no upload. Spreadsheets and drilling-fluid report PDFs are parsed right here in the browser; the packaged Windows build also reads images and works fully offline.

How do I get an API key?
Go to console.anthropic.com and sign up (free).
Open API Keys in the left menu.
Click Create Key, name it (e.g. "CrossCheck"), and copy it.
Paste it in the box above and hit Save. Done.
You pay per question — usually a fraction of a cent on Haiku. The key lives only on your machine. Anyone else using CrossCheck adds their own key in their own copy; yours is never shared and never leaves your device except to talk directly to Anthropic when you press Ask Claude.
