How NeuralSplit Works

NeuralSplit is an AI-powered split testing engine that doesn’t just test your copy—it writes, evolves, and relentlessly optimizes it to drive more conversions. Using advanced bandit algorithms, NeuralSplit generates high-quality, conversion-focused variants, picks winners, and creates new options in real time. You get copy that’s always improving—and always tuned to what actually works.

Unlike generic AI tools, NeuralSplit is engineered for direct response marketing—think Dan Kennedy, not chatbot fluff. Every variant is crafted to drive action, using proven persuasion principles that actually sell.

• NeuralSplit scans your site to understand your business, offer, and audience.
• You create a campaign and add one or more elements (like headlines or CTAs).
• Each element gets multiple variants—AI-generated, manual, or both.
• NeuralSplit distributes traffic using smart algorithms (UCB1, Thompson Sampling).
• It learns which variant actually converts best, and shifts traffic accordingly.
• When a winner emerges, NeuralSplit generates new, even stronger variants based on what’s working.
• This cycle never stops—your copy keeps getting sharper, more persuasive, and more profitable.

NeuralSplit gives you total flexibility when creating content elements:

• Let the AI generate conversion-focused variants from your campaign context—no copywriting required.
• Provide a few sample variants to guide the AI’s tone and direction.
• Use a custom prompt to define style, persona, voice, or structure.
• Combine any of the above for even more control.
• Or skip AI entirely and set your own variants manually.

NeuralSplit is designed to drop into your site or app with minimal effort. Use the API or one of our lightweight SDKs to start serving and optimizing high-converting content instantly.

• Generate your API key from the dashboard
• Choose your language or framework
• Copy the provided integration snippet into your app
• Tell NeuralSplit what content to show—and when to track a conversion

More frameworks and client libraries are on the way.

WordPress example

<h1>[neuralsplit element="headline"]</h1>

<button onclick="trackConversion()">
  [neuralsplit element="cta"]
</button>

Next.js example

export default async function App() {
  const { headline, subheadline } = await getVariants({
    apiKey: "<your_api_key>",
    campaignId: "<your_campaign_id>",
    elements: ["headline", "subheadline"]
  });

  return (
    <div>
      <h1>{headline}</h1>

      {/* Example usage. Move this to a client component */}
      <button onClick={() => trackConversion({ reward: 1 })}>
        Sign up
      </button>
    </div>
  )
}

NeuralSplit uses advanced bandit algorithms like UCB1 and Thompson Sampling to distribute traffic intelligently. High-performing variants get more exposure, while low-performing ones are quietly phased out. The focus is always on maximizing conversions, not just running tests.

Once the model is confident, it selects a winner—then instantly generates new, conversion-optimized variants based on what’s working best.

• Optimization happens in real time—no waiting for fixed test durations.
• Less traffic wasted on poor-performing variants, more on what converts.
• Faster time-to-results and higher ROI than traditional A/B testing.
• Variants evolve automatically—no more one-off tests or stale copy.

You decide how much control you want. NeuralSplit supports:

• Manual mode: You write every variant by hand.
• AI-assisted: Provide a few samples or a tone prompt to guide the AI.
• Fully automatic: Let the AI generate and evolve variants continuously, always focused on conversions.

Switch between modes per element—you're always in control, but the AI is always working to improve your results.

Want to test a new headline? Just create a “headline” element in NeuralSplit. You can:

• Let AI generate 3 conversion-focused options based on your offer and audience.
• Start running traffic to all 3 variants with just a few lines of code.
• After 48 hours, one version is clearly outperforming the rest.
• NeuralSplit declares it the winner and instantly generates 2 new, even stronger variants inspired by it.
• This loop continues—evolving your copy over time, so it always converts at its best.
