Why pupopup

Social proof, in real time

A lone visitor hesitates. A visitor who sees others act, follows.

Popups in 5 min

Write your notifs, pick the style, copy one line of code. No plugin, no account.

AI writes your notifs

Describe your business → AI suggests credible, punchy notifications, ready to paste.

More FOMO = more sales

Seeing others sign up or buy triggers action. It's the most underused conversion lever.

How it works

Write → customize → paste

1

Write your notifs

Signups, sales, reviews… whatever you want to highlight (real ones, no faking).

2

Customize

Position, frequency, duration, emoji. A live preview shows the result.

3

Paste the code

One line on your site and your popups run. On any platform.
