Under the hood of the industry’s most powerful Brand Language Optimization.

Generate, optimize, automate, and analyze language in realtime with Phrasee

If you want to nerd out on the tech behind the tech, you’ve come to the right place!
Phrasee is powered by what we like to call the Phrasee Brain. Here’s what’s in it:

Natural language generation

Natural language generation (NLG) is the AI that generates human language, that is always on brand and brand safe. First, we build a language model tailored to your brand’s style, tone, target audience, and campaign goals (because if we’re going to make you millions, we want to do it right!). Then Phrasee can produce the industry’s most natural-sounding and scandal-proof language, in real time, with a click on the Magic Button.

Deep learning

Deep learning is how we leverage historical data and the results of automated experimentation. Phrasee is always learning from past performance. We apply attention-based deep learning networks to customer and market data in order to predict and deploy top-performing language for your brand. In a nutshell: it gets smarter with every send.

Dynamic optimization

Phrasee X Dynamic Optimization empowers marketers to not only generate, but optimize language in real time. It’s the first and only tool of its kind. With dynamic optimization, Phrasee helps brands respond to customers more nimbly and personally by automatically optimizing language to ensure that the best performing language reaches the widest possible audience.


Advanced multivariate testing means AI that writes better than you – and can prove it. Phrasee uses experimentation at scale to find the best language for your brand and customers. Our data-driven approach tests AI variants against a human-generated control, then deploys the top-performing copy and calculates revenue impact. No Bunsen burners needed – just leave the science to the Phrasee platform while you count the boost in revenue.


Automation means that you can do more with less. Once you load the system with your customer data, campaign goals, and brand standards, Phrasee automatically generates the content you need across the customer journey. Phrasee continuously improves performance – and revenue – over time, without all the manual effort.


Customer insights are a little present from us to your marketing team. We don’t just learn what works – we share those insights with you so you can incorporate them into your marketing plan. Plus, we’ll show you the impact of Brand Language Optimization on your marketing initiatives, which might make you a hot topic around the water cooler.
