Notes from the engineering team

Architecture decisions, round-trip fidelity work, OCR pipeline internals — drawn from the actual codebase, with the tradeoffs and the failure modes we hit along the way.

Why we built Docverix in the browser

We default every PDF, Word, and OCR tool to client-side processing — no upload, no server. Here's the architectural reasoning, the tradeoffs, and where we made exceptions.

Inside the 24-language OCR pipeline

How we run Tesseract.js as a Web Worker across 24 languages, score every word for confidence, and decide when to escalate to an AI vision model. Practical notes from the OCR tool.

Docverix Platform

Need workflow + audit on every doc your team handles?

Docverix Platform turns these tools into a routed, audited pipeline — validator → supervisor → approver, with a complete audit trail.
