SignKit - Offline Signature Extraction: Extract & sign PDFs locally - $29 lifetime

Hey Product Hunt! 👋 I'm Pranay Suyash, and I built SignKit to solve a problem I had: extracting signatures from documents without uploading them to cloud services. The Problem: I needed to extract signatures for contracts but didn't trust cloud services with sensitive documents. Adobe Acrobat costs $240/year. DocuSign costs $120/year. That's $360+ annually for basic signature features. Free online tools compromise privacy or have malware risks. So I built SignKit - a desktop app that processes everything locally. Why SignKit? • Complete privacy - all processing happens locally on your computer • Professional precision with zoom and threshold controls • PDF signing included • One-time payment of $29 (own forever) Perfect for: • Legal professionals handling 20+ contracts/week • Real estate agents processing closing documents • Healthcare providers managing patient forms • Business owners signing routine documents • Anyone who values document privacy Tech Stack: • Python + Qt for native desktop UI • OpenCV for professional image processing • PyMuPDF for PDF handling • Cross-platform: macOS (ARM64 & Intel), Windows, Linux Black Friday Special: Launching today at $29. One-time payment. Own it forever. Download it here: https://signkit.work Test all features before buying. No credit card required for trial. What I'd Love Feedback On: Is the value proposition clear? Pricing - fair for a one-time payment? What features would you want added? Any privacy concerns I should address? Thanks for checking out SignKit! Happy to answer any questions. 🚀
