Question 1

Will my PDFs be shared with anyone else, or end up somewhere on the internet?

Accepted Answer

No. PDFLoom does all of its editing and AI work locally in your browser — your file is never uploaded to a server, so it's never seen by us, stored anywhere, or mixed in with anyone else's documents. Everything happens on your own device.

Question 2

Is PDFLoom really free?

Accepted Answer

Yes. The core editor is free with no account and no API key, including the AI features. Pro is an optional paid plan with higher limits on cloud features such as sharing links and sync.

Question 3

Do I need an internet connection to use it?

Accepted Answer

Only to load the app the first time and to download the AI models once. After that, PDFLoom keeps working offline — there's no server round-trip for editing or for AI features like summarize, translate, or chat.

Question 4

How accurate is the AI (summaries, redaction, chat)?

Accepted Answer

It's best-effort and grounded in your document's own text, but AI can still miss things or get details wrong — always review AI-suggested redactions and summaries before relying on them, especially for sensitive or legal documents.

Question 5

What happens to my file when I close the tab?

Accepted Answer

Nothing persists anywhere outside your device. PDFLoom keeps no server-side copy or history — if you want to keep your work, save the file to your computer before closing.

Question 6

Which browsers does PDFLoom support?

Accepted Answer

Any modern Chromium-based browser (Chrome, Edge, Brave) or Firefox. PDFLoom uses standard browser and WebAssembly features to do the editing and AI work on-device — no plugin or extension required.
