About
GAUGE is a private field journal and AI assistant for people who run oil and gas wells: production engineers, reservoir engineers, lease operators, and pumpers. Log what you see at the wellhead in seconds, build a timeline for every well, and let AI turn your notes into early warnings and clean reports.

- Works fully offline at remote wellsites, no account and no signup
- AI flags entries that look like mechanical trouble, with plain reasons and suggested checks
