Built by people who asked proofreaders what they actually need.
Not a general PDF editor trying to be everything. A proofreading tool that does its job and gets out of the way.
You read carefully. You mark errors precisely. You move through a document systematically, placing corrections that someone else will interpret and act on.
You need marks that are clear, placement that’s accurate, and a tool that doesn’t slow you down with menus, dialogs, and feature bloat.
That’s what Stampede is. A stamp sidebar with your annotations. Tap, place, move on. Nothing else to learn. Nothing else to navigate.
Customisable stamps
Your stamps, your way.
Standard marks — stet, dele, trs, close up, insert, new paragraph. The full set.
Chicago abbreviations — your correction codes as stamps.
Client-specific systems — build a custom set that matches their expectations.
Configurable font, size, colour, and styling. Searchable, reorderable, persistent across every document.

On-device AI
AI that respects your expertise.
You don’t need an app to tell you how to proofread. What you might appreciate is an extra pair of eyes that catches the occasional typo in a 200-page manuscript — the ones that slip through on hour three.
It doesn’t overrule you. It doesn’t make changes. It just says “I noticed this — what do you think?” Use it or don’t. The stamp sidebar works beautifully either way.

Your documents are your business.
NDAs are standard. Unpublished manuscripts, legal filings, medical records — clients trust you with their documents.
On-device AI means those documents never leave your iPad. No cloud uploads. No server-side processing. The default is private.
One-time purchase.
No annual subscription. No “basic” tier that withholds features. No upsell.
We know freelance proofreaders watch their expenses carefully. Every subscription adds up. Stampede is a tool you buy once and own.
