What is Phrasee AI?
Phrasee is an AI marketing language platform specialising in generating and optimising the specific copy elements that most determine email and push notification performance — subject lines, preview text, and call-to-action copy. Unlike general-purpose AI writing tools, Phrasee focuses on performance optimisation: generating copy variants and using real campaign results to learn what language works for each brand's specific audience.
Generative AI brand language produces on-brand subject lines and push copy that adhere to each brand's voice guidelines — not generic content that could be from any company. Phrasee's models are trained on the brand's historical performance data and copy style guidelines to produce content that fits the brand while optimising for opens and clicks.
Automated A/B testing generates multiple copy variants for each campaign and allocates traffic between them — learning which language patterns, emotional triggers, and phrasing styles produce the best engagement for each specific brand and audience segment.
Content analytics track which language elements — urgency, exclusivity, curiosity, social proof — produce the best performance for each brand, building a brand-specific language intelligence model over time. Insights from this model inform future copy generation.
Integrations with Braze, Salesforce Marketing Cloud, Movable Ink, and other enterprise marketing platforms enable Phrasee to operate within existing campaign workflows — generating optimised copy as part of the campaign build process.
With customers including Domino's, Walgreens, and Levi's, Phrasee validates for major consumer brand email and push marketing.
How Phrasee AI works
Phrasee AI runs as llm assistant software built around text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web and api.
