Janus Gate

Stop guessing which copy converts

Automatically and based on data science

The problem we solve. Have a landing page and want to know which copy works best? Create N versions — we tell you the winner by analyzing how users behave (multiple A/B/C tests), powered by a Reinforcement Learning algorithm.

How? Drop a small snippet on your landing page. Janus Gate tests your title, CTA, and text, then shows winners more often as people visit.

How it works

Someone lands on your page. Janus Gate shows one mix of title, CTA, and text, then watches what they do — conversion click, scroll, time on page, or a bounce. That visit is recorded as a success, a soft success, or a failure.

Then the next visitor arrives. Our proprietary Reinforcement Learning algorithm chooses which version to show — sometimes exploring a weaker option to learn more, sometimes leaning toward what already works.

Visit after visit, each one adds knowledge. The algorithm explores, updates, and uses that knowledge to propose a better mix — converging on the copy that performs best. Stronger variants get more traffic automatically; you watch it on the monitor.

Convergence, at the end. As evidence piles up, the algorithm becomes more confident. The version with the highest chance of converting is shown more and more often — automatically — while weaker options fade into the background. You do not flip a switch to “pick a winner”: the page quietly settles on the copy that works, and the monitor turns green when it is sure enough.

Setup in a minute

What you do once. Create a project, paste one script in your page <head>, and mark the title, CTA button, and text below with a few variants each. Full steps — and your exact tracking ID — are in the guide.

  1. 01

    Create a project

    In the dashboard, add a landing and get your private tracking ID.

  2. 02

    Paste the script

    One tag in <head> with your tracking ID — not the demo id.

  3. 03

    Mark title, CTA, body

    List your variants on each element. On the CTA, mark the click that counts as a conversion.

Results

The monitor tells you what's winning

No statistics degree required. Each variant gets a simple color:

  • Green — best so far
  • Yellow — leading, still unsure
  • Orange — still in the race
  • Red — behind
  • Grey — too early (not enough visitors yet)

One script tag. A few attributes on title, CTA, and body. The guide shows a full before / after example.
