Questions & Answers

As answered by people managing NullKit.app and GhostDocs.

What makes your product unique?

GhostDocs's answer:

GhostDocs operates on a 100% zero-upload architecture. While conventional document tools upload files to remote servers, GhostDocs executes all PDF splitting, merging, redaction, and image conversions locally inside your browser using HTML5 Canvas and WebAssembly. You can disconnect your internet, turn on Airplane Mode, and every tool still works.

Why should a person choose your product over its competitors?

GhostDocs's answer:

Complete privacy, no paywalls, and no file limits. Competitors like iLovePDF and Smallpdf upload your files to their servers and restrict usage behind daily limits or paid subscriptions. GhostDocs processes documents directly in your device's RAM with no file size limits, no watermarks, and zero account sign-up required.

How would you describe the primary audience of your product?

GhostDocs's answer:

Privacy-conscious professionals, remote workers, legal and financial consultants, journalists, and everyday web users who need to handle sensitive documents (such as tax filings, bank statements, contracts, and ID scans) without risking cloud leaks.

Who are some of the biggest customers of your product?

GhostDocs's answer:

  • Independent legal and accounting professionals
  • Freelancers and remote teams
  • Privacy-conscious everyday web users

What's the story behind your product?

GhostDocs's answer:

We created GhostDocs after realizing that simple everyday tasks—like blacking out an account number or combining two pages—forced users to upload confidential documents to anonymous cloud servers. We engineered a suite of zero-upload browser tools to prove that modern web apps can deliver fast, professional utility without sacrificing user privacy.

Which are the primary technologies used for building your product?

GhostDocs's answer:

React, TypeScript, Vite, WebAssembly, HTML5 Canvas API, pdf-lib, pdfjs-dist, and binary EXIF parsers.
