AnDocs

AnDocs is basically Google Analytics for your PDFs — except actually useful because it tracks the stuff that matters for sales docs, like full reads not just opens, time per page, and CTA clicks. The engagement breakdown by device, browser, location, referrer and UTM is solid for figuring out which channels are actually converting. Free tier gets you one active document, which is enough to test it out before committing to paid, and you only pay for what you're actively using so there's no waste. For anyone sending proposals or investor updates who hates asking "did you see that?", this is the move.
