ask, don’t skim
An AI PDF assistant that shows its work.
Velox PDF is an AI PDF tool that reads the whole document before it answers — ask it anything and it tells you exactly where the answer came from, not a guess, a page number.
Chat with PDFs
Ask your PDF a question in plain English and get an answer pulled from the document you're actually looking at.
PDF summarizer
Turn a 40-page report into the two paragraphs you needed — a real AI PDF summarizer, not a bullet-point skim.
Explain
Ask it to put a dense clause or a technical paragraph into plain language.
Citation support
Every answer names the page and section it came from, so you can check it in one click.
Fast local search
Velox PDF indexes the document on your Mac, so finding a phrase is instant, not a round trip to the cloud.
Built for Apple Silicon
A native Swift app, not an Electron shell — starts fast, stays light, and feels like it belongs on your Mac.

how it works
Three steps, no learning curve.
Open a PDF
Drag it in or set Velox PDF as your default viewer. It opens instantly — nothing to upload first.
Ask, highlight, or sign
Type a question, drag a highlighter across a paragraph, or drop in your signature — whatever the page needs.
Get a cited answer
The assistant answers with the page and section it used, so you can verify it in one click and move on.
see it in use
One app, three kinds of PDF days.
and yes, still a full markup app
Every markup tool, still built in.
Velox PDF is a full PDF annotation toolset, not just an AI chat window — highlight, draw, sign, and run on-device OCR on scanned pages.
Draw
Freehand ink that actually looks like ink, not a mouse trail.
Highlight, underline, strike
Select text, pick an action. No dialog box, no fuss.
Shapes & lines
Boxes, circles, and arrows for pointing at the thing you mean.
Notes & text boxes
Say what you mean, right where you mean it on the page.
Sign
Draw your signature once, drop it on anything, any size, forever.
Ask AI
Summarize a page, extract key points, or translate a paragraph in place.
OCR that just works
Even a scanned page becomes text you can copy and search.
Thumbnails & zoom
Jump to any page, at any size, without losing your place.
new
Sign it like you mean it.
Draw your signature once with the trackpad or mouse. Velox PDF trims it, remembers it, and lets you drop it onto contracts, forms, and permission slips at whatever size fits — no printing, no scanning, no third app.

questions
Before you ask.
What AI models does Velox PDF support?
Velox PDF's built-in AI works free with no setup — pick Fast, Balanced, or High Perf in Settings depending on how much you want to wait for an answer. If you'd rather use your own account, you can add your own API key instead.
Does Velox PDF work offline?
Yes for everything except the AI assistant. Highlighting, drawing, signing, page management, and search all run fully offline. Asking a question needs a connection, since it talks to a model in the cloud.
Is my PDF private?
Your PDFs stay on your Mac for viewing, highlighting, drawing, signing, and local search — that never uploads anywhere. Asking the AI assistant a question sends only the relevant text to generate an answer: to Velox PDF's own servers on the built-in AI, or directly to your own provider if you've added your own key.
Does it work on Apple Silicon?
Yes — Velox PDF is a native Swift app compiled to run on M-series Macs, as well as Intel Macs, on macOS 14 (Sonoma) or later.
Can I chat with scanned PDFs?
Yes — run OCR on a scanned page (one click) and the text becomes selectable, searchable, and answerable by the AI assistant just like any other PDF.
What happens after my trial?
On day 15, your card is charged $9.99 and your subscription continues monthly. Cancel any time before then from the link in your receipt email and you won't be charged.
Can I switch from monthly to a lifetime license later?
Yes — just purchase the $39.99 lifetime license whenever you're ready and cancel your monthly subscription.
