KeptPDF's answer

KeptPDF runs entirely in your browser. Your file, and the text inside it, never leaves your device. Not to an AI, not even to us. You can open your browser's network tab and watch: the document bytes never go out.

Most online PDF tools upload your file to a server first, and some "AI redaction" services quietly send your document text to a third-party model. That is the exact risk people are trying to avoid when they redact something.

KeptPDF also does true redaction. The text is removed from the file, not covered with a black box you can copy out later. Every redaction produces a verification certificate you can share with the file.

EditDocx's answer:

EditDocx is a free online DOCX editor that runs entirely in your browser — your document is never uploaded to a server. Unlike Google Docs or Word Online, there is no account, no cloud drive, and no subscription. You get native .docx WYSIWYG editing (not a lossy import), auto-save to your device, recent files, PDF export, dark mode, and 16 UI languages — all with zero server-side document processing.

KeptPDF's answer

Three reasons.

Privacy you can verify, not just a promise. Processing happens locally in the browser, so there is no upload step to trust. We do send anonymous usage counts for quota, and we say so plainly, but never your document.

Real redaction with proof. Removed text is permanently gone, and you get a certificate showing the file was checked for leftover extractable text. Automated detection cannot catch everything, so a final human review is still your job, and the tool says that too.

It works on a phone. Most PDF suites assume a desktop. KeptPDF was built and used on a phone first, so redacting a document while you are standing in a hallway actually works.

EditDocx's answer:

Choose EditDocx when privacy and speed matter more than real-time collaboration. Word Online and Google Docs require accounts and store files in the cloud; EditDocx requires neither. Your files stay on your machine, edits auto-save locally, and you can export to DOCX or PDF in one click. It is ideal for quick edits on a guest PC, Chromebook, or Mac without Microsoft Word — free, no signup, no install.

KeptPDF's answer

Anyone who has to hand a document to someone else and needs the sensitive parts gone first.

In practice that is solo attorneys and small law firms, accountants and tax preparers, healthcare and records staff handling requests, HR teams, and individuals dealing with their own medical, legal, or financial paperwork.

The common thread is not an industry. It is a person who cannot upload a confidential file to a random website, and who does not have an enterprise IT budget to solve it.

EditDocx's answer:

EditDocx is built for people who need to open and edit a Word file quickly without creating an account or uploading to the cloud. Typical users include professionals handling contracts and NDAs, HR and legal teams on shared computers, students and freelancers without Office installed, Chromebook and Linux users, and anyone who wants a private, free alternative to cloud-based word processors for everyday .docx tasks.

KeptPDF's answer

A family member got seriously ill. We spent most days at the hospital, and straight answers were hard to come by, so we leaned on AI tools to make sense of the records, notes, and lab results.

But you cannot paste a medical record into an AI chat. You have to strip the names, the ID numbers, the diagnoses first. And almost every tool we found either wanted to upload the whole file to a server, or "auto-redacted" by sending the document text to an online AI. That was the exact thing we were trying to avoid.

Most of this was happening on a phone, at a bedside. So I built the tool I needed: redaction that runs on the device, works on mobile, and never sends the file anywhere. That turned into KeptPDF, which is now a full PDF suite with over 20 tools, all local-first.

EditDocx's answer:

We built EditDocx because document editing should be fast, free, and private. Most online word processors force you to sign in and send files to the cloud — even for a five-minute edit. EditDocx takes a different approach: open a tab, drop in your .docx, edit locally, and download when done. It is powered by docx-editor, an open-source browser-native DOCX engine, and deployed as a static web app so your content never touches our servers.

KeptPDF's answer

The app is plain JavaScript with no front-end framework, which keeps it fast and keeps the code auditable.

PDF work happens in the browser using pdf.js for rendering and pdf-lib for writing. Text recognition uses Tesseract running as WebAssembly. Password and encryption handling uses a WebAssembly build of qpdf. It is a Progressive Web App, so it installs and works offline.

The thin server side is Node on Vercel, with Postgres for accounts, Stripe for billing, and Resend for email. None of those ever see a document.

KeptPDF's answer

KeptPDF is early and independent, and we do not publish customer names. The product is privacy-first by design: we never see your documents, and we do not track who our users are or what they work on. Publishing a client list would sit badly next to that.

The user base today is mostly solo attorneys, small firms, accountants, and individuals handling their own records.

EditDocx's answer:

EditDocx is a free tool for individual users — we do not sell enterprise licenses or track named corporate accounts. Our users are typically:

Privacy-conscious professionals editing contracts, NDAs, and HR forms People on guest or shared computers (libraries, client sites, airport kiosks) Chromebook and Linux users without Microsoft Word installed Students and freelancers who need a quick .docx edit without signing up for Google or Microsoft
