What if you had them working endlessly to create awesome content for your campaigns guaranteed to drive you a high ROI? We’ve done exactly this!

Well… sort of. 😉

About Merlin AI

Generative AI has taken the Martech world by storm.

With the release of multiple NLP and Large Language Models (LLMs) such as GPT, Claude, PaLM 2, Falcon, LLaMa, and various others, the adoption of Generative AI has spiked in the past few months.

We are excited to announce that we have successfully merged the advantages of Generative AI with the world of Customer Engagement with the launch of our latest product, Merlin AI.

Unlike other Generative AI platforms, Merlin AI learns from the performance of your past campaigns, understands context based on your audience and use case, considers the positive and negative impact of certain keywords, and helps you build high ROI-driving campaigns.

Merlin AI Now Supercharges Campaigns Across Multiple Channels

We’re excited to share that MoEngage’s Generative AI engine, Merlin AI for Copywriting, has gotten new upgrades! Marketers can now tap into its advanced AI capabilities to generate highly engaging copy across –

  • Push Notifications
  • Emails
  • In-App Messages
  • Cards
  • On-site Messaging channels.

Since its initial launch for Push campaigns last year, Merlin AI for Copywriting has received tremendous customer love, with top consumer brands leveraging it to drive remarkable results.

Deutsche Telekom used it for their prepaid activation campaigns and saw a staggering 65% jump in click-through rates. They found that the AI-generated copies from Merlin AI outperformed their manually crafted ones, enabling them to connect with customers more effectively through contextually relevant messaging.

By understanding past campaign performance data, historical keywords, campaign goals, and channel dynamics, Merlin AI tailors the content to resonate with your audiences. This allows marketers to boost key metrics like email open rates, in-app click-through rates, and overall engagement.

Oh, and Merlin AI directly integrates with MoEngage’s campaign builder, meaning you don’t have to navigate to a different page to use our Generative AI engine and then switch back to your campaign creation screen. Other platforms require you to switch between the Generative engine and campaign creation pages, which is great if you’re looking for a quick workout for your fingers and don’t mind breaking your flow.

Why did we call our Generative AI engine ‘Merlin AI’?

Merlin is a mythical figure prominently featured in the legend of King Arthur.

He is known to be one of the greatest wizards of all time. Merlin AI is inspired by his unparalleled proficiency in magic and performing feats other wizards could not.

What Makes Merlin AI the Best in the Business?

Merlin AI can automate content creation, saving you time and effort.

Generative AI models can be used to create campaign copies, campaign assets, product descriptions, and a lot more!

You can build a steady stream of creative and consistent content thanks to Merlin AI.

With Halloween approaching, let’s consider you want to create a Push Notification campaign targeting your Gen Z audience, announcing a sale.

Here’s what other Generative AI tools would be able to generate:

This Push Notification copy does the bare minimum of announcing a Halloween sale for the Gen Z audience. However, it lacks certain keywords and has a generic tone and style.

Now, let’s try to recreate the same Push Notification using Merlin AI and see what makes it unique.

1. Merlin AI’s easy-to-use prompt builder saves time.

With Merlin AI, you can spend less time thinking of a prompt that will give you the best copies.

You can easily pick filters and criteria to create copies for a specific campaign, use case, and audience using Merlin AI’s prompt builder. You can also define the tone and writing style of the content using an intuitive UI.

2. Merlin AI suggests keywords based on their impact on your previous campaigns.

Our Generative AI engine learns from your historic campaign performances and trains itself to create content using the most impactful, trending, and necessary keywords that drive high results.

Merlin AI adds impactful keywords (that have driven higher engagement or conversion goals in the past) and automatically removes negative keywords (that correlate with lower engagement, from its copies.

Next, let’s give Merlin AI some more context about our audience and the tone and style we want to pick for this campaign.

By selecting ‘Gen Z Enthusiasts’ as the segment, Merlin AI understands the audience you want to build this campaign for. By selecting ‘FOMO’ and ‘Emoji Language,’ Merlin AI further understands the emotion you want to convey and in which writing style.

3. Merlin AI understands context, audience, tone, and writing style.

You can prompt Merlin AI to create or modify content with a specific tone. For example, Formal, Quirky, Persuasive, Empathetic, Humorous, and more. Marketers can also ask Merlin AI to create content with a particular persona or celebrity writing style like Richard Branson or Steve Jobs.

After we hit Generate, here’s the copy Merlin AI suggests:

The difference between the Push Notification copy generated by the generic AI tool and Merlin AI is night and day!

Don’t you feel eager to get started already? Hold on, there’s more!

Let’s say you have another great idea for the campaign, and you want to run an A/B test to experiment and see which copy works best.

Do you have to go back and revisit the campaign parameters? No! You can immediately create a new variation and (if needed) give new prompts for the other variant.

4. Merlin AI lets you regenerate new copy variations with a single click.

You can create more options without returning to the first step of your campaign creation process and re-enter the campaign parameters.

A/B testing and experimentation is important when you’re running large-scale campaigns. Let’s see how Merlin AI helps you create multiple variants for testing.

To create multiple variations for A/B testing, we’ve selected the existing Push Notification copy. Immediately, Merlin AI automatically pulls in the relevant context.

You can tweak the prompts here or directly generate new variations.

5. Merlin AI creates multiple variants for A/B testing in seconds.

Our Generative AI engine simplifies your A/B testing and automation processes by generating multiple variations of assets and copies (such as content for push notifications, emails, SMS, advertisements, subject lines, creative assets, social media graphics, and more!) with a single click!

You can then test these variations against each other, optimizing your campaigns for maximum ROI. Read more about MoEngage’s Campaign Optimization suite here.
