Stampede PDF

PDF annotation, rethought for iPad.

Your marks. One fluid gesture.

Create text-based stamps for any annotation you use. Approval marks, editorial shorthand, your own codes, any system you prefer. Each stamp has configurable font, size, colour, and styling. Stamps live in a sidebar that swipes in from the side. Drag onto the page, done. They persist across documents.

AI assists. You decide.

On-device AI using Apple’s Foundation Models flags spelling, grammar, and consistency issues for your review. This isn’t autocorrect. The AI highlights what it found; you decide what to stamp. Bring your own API key for cloud models when you need deeper analysis. Your documents stay private by default.

Look it up without leaving the page.

Select any text, tap Research. A grid of buttons takes your selection straight to Google, Wikipedia, Merriam-Webster, Perplexity AI — or any reference site you add. No switching apps, no copying and pasting, no losing your place. Select, tap, answer. All without leaving the page.
