About Nupura
I write about document AI because I spent the better part of a decade watching smart people lose hours every week to broken paperwork pipelines. My first encounter with OCR was at a fintech where we processed a few thousand invoices a month — and our ops team was hand-keying half of them because the OCR vendor kept choking on tables. Today I help builders at DocsAPI cut through the noise: what actually works, what's marketing fluff, and what to ship this quarter. I lean on real numbers, real customer stories (anonymized where needed), and the kind of detail you can only get from being elbows-deep in the work. If a guide on this site feels overly polite, blame editing. If it feels like a friend explaining something over coffee, that's the goal.
