## What is Butterfly by Subbi?

Butterfly replaces the hand-drawn "butterfly diagram" paperwork that utility field crews fill out on every manhole inspection.

Photograph each wall, mark the duct positions on a simple grid, record the circuits and their condition, and Butterfly produces the finished inspection deliverable — ready to hand to the office.

BUILT FOR THE FIELD
• Works fully offline. Everything you capture is saved on your phone first and uploaded when you get a signal — you are never blocked underground or out of range.
• Photograph all four walls; duct positions map straight onto the inspection form.
• Record circuits, splices, cable codes, and per-circuit condition with the trade's own temperature / IR stop-work rules built in.
• Generate the finished workbook and a photo report on the phone.

FOR THE OFFICE
• Completed inspections back up automatically to your company's private, access-controlled space.
• A web console lets the office see the crew's work and pull reports.

YOUR DATA, IN CANADA
• Your inspections and photos are stored in Canada (Montréal).
• No analytics, no advertising, no tracking, no location tracking — none of it is in the app.
• Your inspections belong to your organization, not to us. Delete your account from inside the app at any time.

Butterfly is a professional tool for working crews. It is not a consumer app and carries no advertising.
