QuickSign: Signature & Stamp
by Butler Labs LLC
Description
Stop faking it with a typed name. QuickSign lets you sign documents with your actual handwritten signature — captured by camera, refined by AI, and placed exactly where it needs to go.
WHY QUICKSIGN
• Real camera signature — scan your ink signature from paper; AI removes the background so it looks crisp on any document
• Stamps & seals — create professional round stamps and custom seals in seconds, no design skills needed
• Total privacy — every signature, stamp, and document stays on your device; nothing is uploaded to any server, ever
WHO USES QUICKSIGN
Real estate agents who need to countersign contracts on the go. Notaries who want a clean digital workflow without compromising authenticity. Attorneys handling NDAs and engagement letters between meetings. Freelancers signing client agreements before a project kicks off. Small business owners processing invoices, delivery notes, and service agreements without the overhead of enterprise e-sign platforms.
HOW IT WORKS
1. Import or photograph your document — open any PDF from Files, Mail, or your camera roll
2. Place your signature or stamp — tap to add, drag to position, pinch to resize; done in under a minute
3. Share or save — export as a flattened PDF ready for email, print, or filing
FEATURES
• Camera scan → AI background removal for natural-looking signatures
• Draw directly on screen as an alternative signature method
• Create and manage multiple signatures and stamps
• Annotate PDFs: text boxes, highlights, freehand drawing, shapes
• Fill in form fields on interactive PDFs
• Multi-page document support with full page management
• Works offline — no internet connection required
• Export to PDF, share via AirDrop, Mail, or any app
PRIVACY
QuickSign is built privacy-first from the ground up. Your signatures, stamps, and documents never leave your device. There is no account to create, no data synced to a cloud, and no third-party servers involved. Everything is processed locally using on-device AI.
