Sumext's answer

Sumext combines AI-powered invoice extraction, OCR, contractor submissions, expense submissions, and direct accounting software sync in one simple workflow. Instead of manually entering invoice data, users can upload or receive documents through email, WhatsApp, or contractor portals, review the extracted data, and sync it directly to accounting platforms like Xero, QuickBooks, Zoho Books, and TallyPrime.

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.

Sumext's answer

A person should choose Sumext because it is built specifically to reduce manual bookkeeping work and make invoice processing faster, more accurate, and easier to manage. Sumext supports batch uploads, AI data extraction, approval workflows, and direct sync with popular accounting systems. It is especially useful for businesses, contractors, and accounting teams that want to save time, reduce errors, and keep financial documents organized.

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.

Sumext's answer

Sumext is designed for small and medium-sized businesses, accounting firms, bookkeeping teams, contractors, and finance departments that handle invoices, receipts, bills, and expense submissions. It is ideal for teams using Xero, QuickBooks, Zoho Books, or TallyPrime who want to automate document collection, data extraction, approval, and accounting sync.

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.

Sumext's answer

Sumext was created to solve a common problem in accounting: too much time is wasted on manual invoice entry, document collection, and expense processing. Businesses often receive invoices from different channels such as email, WhatsApp, contractors, and scanned documents. Sumext brings all of this into one smart platform, using AI and OCR to extract data, organize documents, and sync approved entries directly with accounting software.

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.

Sumext's answer

Sumext uses AI-powered data extraction, OCR technology, cloud-based document processing, automation workflows, and accounting software integrations. The platform is built around secure document handling, intelligent invoice recognition, API-based sync, and structured financial data processing.

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.

Sumext's answer

• Customer names are not publicly disclosed at this stage.
• Sumext serves small businesses, accounting firms, bookkeeping teams, contractors, and finance departments.
• Sumext is suitable for companies using Xero, QuickBooks, Zoho Books, and TallyPrime.

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.
