Utilities that do the work and forget your files.

Axiom Opus Labs builds fast, privacy-first, intelligent utilities for document processing and digital media workflows. Three shipped products, one engineering standard: your files are processed, not collected.

  • Browser-native
  • No sign-up to start
  • Files deleted after processing

The standard across every product

  • No file retention
  • Sub-second common operations
  • AI where it earns its place
  • Works in the browser

Shipped products

Three products. One set of rules.

Each product owns its craft and its accent colour — and inherits the same privacy model, the same speed budget and the same interface grammar.

How we build

Three constraints we design against.

Privacy is the default path

Basic operations never leave the device. What does go to a server is processed and dropped — file contents, auth headers and tokens never reach a log or an error report.

Speed is a budget, not a hope

Common operations run in the browser. Heavy work goes to services sized for it, so a compress or a convert finishes while you are still looking at the page.

Intelligence where it pays

Models handle the jobs deterministic code does badly — OCR, upscaling, background removal, summarisation. Everywhere else, plain fast code wins and we use it.

Engineering

A small stack, run deliberately.

One lab, three products, a shared platform. Every service is placed where its data already lives, and every recurring cost is decided before it is created rather than explained after it appears on an invoice.

What the Opus suite is growing into.

Nothing is in limited access. A product is listed here when it is ready to use, not before.

Nothing in limited access

OpusPDF, OpusImg and OpusStride are live. The next utility will be named here when it is ready to open.
