The problem

Why Gearbox exists

Grammar tools don’t know your style guide, and fact-checking every claim by hand doesn’t scale on a lean desk, or against the flood of viral WhatsApp forwards.

How it works

Two tools, one pass

01

Brush the copy

Capitalisation, attribution formats, number style, headline conventions and editorial voice, enforced from your style guide. Not just grammar.

Questions

Gearbox, answered

Last updated

Is Stylesheet Brush a grammar checker?

No. It applies your publication’s own rules: capitalisation, attribution, numbers, headline style and voice.

Should editors rely on the verdict alone?

No. Every verdict comes with citations so an editor can review the evidence and context.
