What is a Certificate of Insurance (COI)?
A COI (often an ACORD 25 form) is a one-page summary proving a business carries insurance — what types, how much, and until when. Before you let a contractor or vendor work for you, you check their COI to make sure you're protected if something goes wrong.
Do I need to understand insurance to use this?
No. Drop in the certificate and we explain everything in plain language — what's covered, what's missing, and exactly what to ask for. It's built so anyone can use it, while being precise enough for a professional risk manager.
Is a photo from my phone good enough?
Yes. A clear, well-lit photo of the certificate works — we read it directly. PDFs give the most accurate results.
Is it free? Is my document stored?
Trying it is free with no signup. Your document is used only to produce your report and isn't stored. For tracking many vendors and automatic expiration alerts, TachyonTracker offers paid plans.
