The problem

One static page can't resonate with everyone.

A CTO and a CEO scan the same page for the same thing, just from different angles, one technical, one business, but every visitor gets the same static words either way. Everywhere else, the internet already adjusts for who's looking: your feed, your recommendations, your search results. Websites haven't caught up.

What Proppers does

Your page's selected text components adapt to the user who's visiting the site.

01

Rewrite the page components from visit context

Proppers uses signals like campaign, source, and device to choose the clearest message for each visit, then changes the page around that message right before the user lands.

02

You choose what to pick as a signal

You tell Proppers whether you want copy changing based on customer lifecycle stage, referral link, device, etc., and Proppers will keep an eye on it.

03

Let the page respond as people read

When someone spends time on a section, Proppers can rewrite another part of the page to follow that interest. The message keeps moving with the visit.

Live Demo

Pick a persona and see how Proppers' page dynamically adapts.

Each choice opens a new tab and writes the site live from that visit's context. Same page, different argument.

Consideration LinkedIn Awareness Ads A professional who just clicked. We'll argue from that campaign. Technical Hacker News Skeptical, mechanism-first. Show how the loop actually works. Consideration Google Search They're comparing tools. Help them choose Proppers over a variant farm. Consideration ChatGPT They asked a model, then landed here. Make the category difference sharp. Awareness Meta Ads Cold traffic from a feed. Teach what Proppers is, in plain language.

How it works

Load, read the visit, rewrite, then rewrite again.

Most personalization is a rules engine plus a pile of approved variants. Proppers is a prompt: your brief plus this visit, generated live, logged so you can see what happened.

  1. See the visit

    A client script captures referrer, campaign params, device, and local time, and posts it with the current page copy.

  2. Write from the brief

    The backend combines that context with your value props and voice, calls the model, and returns copy for every section.

  3. Follow the attention

    Dwell past a few seconds on a block and a second live call reshapes another section around what they actually read.

Who this is for

Built for brands that get traffic from various sources.

For brands getting visits from different sources, running multiple GTM strategies, growing fast, and needing to optimize fast.

My paid landing page says the same thing to a branded search click and a cold LinkedIn ad. That is wasted spend. The campaign already named the argument. The page should too.

Head of Growth B2B, paid in plus organic — composite

We ran out of statistically valid tests before we ran out of opinions. I do not want another winner from last quarter. I want the page to argue from this visit.

Founder Early-stage, writing copy themselves — composite

If I send UTMs and the hero does not change, the campaign was a lie. I need a system that treats the query string as a brief, not as analytics decoration.

Performance marketer Agency and in-house media — composite

This page is the demo. The next one can be yours.

Bring a brand brief. We wire visit context, live rewrite, dwell follow-up, and a generation log. No variant matrix. No approval queue. Exploration, not a production safety net.
