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.

NoteOCR's answer:

Unlike standard OCR tools that only provide a text "dump," NoteOCR specializes in Document Reconstruction. It uses a sophisticated AI engine that recognizes the geometry of a page, allowing it to preserve the original formatting including headers, indents, and complex table structures directly into editable Word and Excel files. This removes the need for manual reformatting after conversion.

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.

NoteOCR's answer:

NoteOCR ease the gap between physical ink and digital productivity with a 99.2% accuracy rate on difficult cursive and messy handwriting. While competitors often struggle with non-standard scripts, NoteOCR provides an integrated Online Document Workspace. This allows users to not only convert but also edit, annotate, and securely store their documents in the cloud for access across all devices, all within a single interface.

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.

NoteOCR's answer:

Our primary audience consists of knowledge workers and students who deal with high volumes of handwritten data. This includes researchers digitizing archives, medical professionals processing patient notes, and students transforming lecture scribbles into study guides. Additionally, we serve logistics and finance teams who need to extract handwritten table data from forms and delivery notes into structured Excel spreadsheets.

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.

NoteOCR's answer:

NoteOCR was born out of a common frustration: the hours wasted manually retyping handwritten brainstorming sessions and field notes into digital documents. We realized that while "text recognition" existed, "document understanding" did not. We set out to build a tool that doesn't just read letters, but understands the layout of the paper, giving founders and professionals their time back by automating the most tedious part of the digitization process.

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.

NoteOCR's answer:

NoteOCR is built on a modern MERN Stack and AI stack focused on speed and precision. We utilize Transformer-based neural networks and CNNs (Convolutional Neural Networks) for visual pattern recognition. The platform's infrastructure is powered by MERN STACK and Vercel for high-performance delivery, while our backend includes advanced Large Language Models (LLMs) for contextual error correction to ensure the highest possible accuracy.

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.
