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.

AfroTools's answer:

Accuracy and coverage. Most alternatives offer one or two African countries as an afterthought. AfroTools is built ground-up for Africa, covering PAYE, VAT, payroll, and productivity tools across all 54 nations. We also offer an API for developers and fintechs who want to embed African financial logic into their own products.

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.

AfroTools's answer:

AfroTools is the only platform built exclusively for Africa's 54 countries, with calculation logic tied to each country's actual tax laws, not generic formulas with African labels. We update in real time when laws change, for example, we were among the first to reflect Kenya's SHIF/AHL changes. Every tool is country-specific, legally grounded, and free to use.

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.

AfroTools's answer:

HR professionals, accountants, payroll managers, finance teams, and developers across Africa. We also serve African fintechs and SaaS companies that need compliant calculation engines without building them from scratch.

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.

AfroTools's answer:

AfroTools was built out of frustration that there was no reliable, Africa-first financial tools platform. Every existing tool was either too generic, too expensive, or built for Western markets and poorly adapted for Africa. We set out to fix that, one country at a time, starting with the six largest economies and expanding to all 54.

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.

AfroTools's answer:

Plain HTML, CSS, and JavaScript — no heavy frameworks. This keeps the platform fast, accessible on low-bandwidth connections, and easy to maintain. Tools are deployed on Netlify with serverless functions powering the AI advisor layer via the Anthropic API.

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.

AfroTools's answer:

Thousands of HR professionals and payroll managers across Nigeria, Kenya, Ghana, South Africa, Egypt, and Tanzania use AfroTools monthly for PAYE and tax calculations Accounting firms and finance teams in East and West Africa rely on AfroTools for country-specific compliance calculations Developers and fintech builders across Africa use AfroTools as a reference engine for embedding African tax logic into their products Small and medium businesses across 6 African countries use AfroTools for payroll processing and financial planning
