Hi Product Hunt! I’m Dion, the creator of AirSign. Like many of you, I got tired of paying monthly subscriptions (like DocuSign or Adobe Acrobat) just to sign a simple PDF agreement. But even worse: why should sensitive contracts, NDAs, or tax documents be uploaded to third-party cloud servers just to add a signature? That’s why I built AirSign: -100% Offline & Private: Zero cloud uploads. Your documents never leave your computer. Ultra Fast: Drag & drop PDFs, PNGs, or JPGs and sign in under 5 seconds. -Natural Signature & Custom Text: Smooth drawing canvas, instant resize handles, and full format control. - One-Time Payment: Buy it once, own it forever. No subscriptions. You can try the live web trial demo directly in your browser: https://getairsign.vercel.app I’d love to hear your feedback, and I'll be here all day answering any questions!
