Questions & Answers

As answered by people managing PdfToolStack and PDFBetter.

Who are some of the biggest customers of your product?

PDFBetter's answer:

  • Freelancers and small businesses
  • Real estate and property management teams
  • Legal, accounting and tax professionals
  • HR and operations teams

What makes your product unique?

PDFBetter's answer:

PDFBetter is an AI-native PDF editor: the AI agent is part of the editor, not an add-on. Type what you need, like "redact every SSN", "fill this with my info" or "merge these three and compress", and it does the job in your document. Every AI edit appears as a proposal you approve with one click, and you can undo it in one step. Every answer and summary cites the page it came from, and quotes are checked word for word against that page before you see them.

It also does everything else in one place: edit existing text, fill forms and build fillable ones, sign and request signatures, convert, OCR in 48 languages, compress, redact, share and fax. Many tools run entirely in your browser, so the file never leaves your device. Use it on the web, on Mac and Windows, on Android, on iPhone and iPad, as a Chrome extension, or inside ChatGPT and Claude.

Why should a person choose your product over its competitors?

PDFBetter's answer:

Because you know the deal before you start. PDFBetter has a real free plan, not a trial: no card, no end date and no watermark on your downloads, and many tools work with no account at all. Every tool page says what's free and what needs a plan, and the app charges exactly what the pricing page says. Paid plans start at $3.25/month billed yearly. Pro, with e-signatures, forms and 500 AI credits a month, is $10/month billed yearly.

You also get AI you can check. Answers come with page citations and verified quotes, so you never have to trust a summary blindly. Signed documents are digitally sealed and carry their audit trail inside the file, and signing records are kept for 7 years. When you're ready to automate, PDFBetter connects to Zapier, Make, Google Drive and AI agents through its MCP server.

How would you describe the primary audience of your product?

PDFBetter's answer:

Anyone who works with PDFs and wants to finish the job fast, without paying for an expensive suite. That includes freelancers and small businesses sending contracts, invoices and proposals for signature, and real estate, property management and insurance professionals handling forms every day. It also includes legal, accounting and tax teams who need redaction, Bates numbering and answers they can verify, and HR, healthcare, education and nonprofit staff collecting forms. Sales and operations teams use it to automate document work with Zapier, Make or AI agents.

What's the story behind your product?

PDFBetter's answer:

Most people open a PDF tool to finish one document. Too often they do the work, then hit a paywall, a trial they never asked for, or a result that isn't what it looked like. We built PDFBetter to be the PDF editor we wanted to use ourselves.

That means a few simple promises. Prices you can read in one table, before you start. Tools that tell you what they can't do (whiteout isn't redaction, and we say so). Jobs that run on your own device whenever possible. And AI that shows its work, with cited pages, checked quotes and edits you approve.

PDFBetter launched in 2026 and is built by AI Generated Inc. It's available in English, Spanish, Japanese, French and German, with local templates and official forms for each market.

Which are the primary technologies used for building your product?

PDFBetter's answer:

PDFBetter is built with Next.js, React, TypeScript and Tailwind CSS. pdf-lib and PDF.js handle PDF editing and rendering, and Cloudflare Workers, Containers and R2 handle file processing and encrypted storage. Data lives in PostgreSQL with pgvector, accessed through Drizzle ORM. AI runs on the OpenAI API, OCR on Tesseract (48 languages), and billing on Stripe. The native apps are built with SwiftUI for iPhone and iPad and Kotlin with Jetpack Compose for Android, and there are desktop apps for Mac and Windows.
