Jacquard

Jacquard is the enterprise agentic AI platform for brand messaging at scale, rebranded from Phrasee in June 2024. Founded in London in 2015, the company evolved from an AI email subject line optimization tool into a comprehensive agentic platform handling the full lifecycle from brief to deployment across enterprise brand operations. Jacquard calibrates each brand's specific language and voice into its AI models. It then uses that calibrated voice to generate content across email, web, app, and push notification channels in 17+ languages with up to 2,500 variants per brief. Confirmed production customers include TUI Group (travel), eBay, Domino's, Virgin Holidays, and Gumtree, spanning retail, DTC, and travel verticals. Core AI capabilities start with brand voice calibration and protection, which encodes brand-specific language rules that govern all AI output. AI content generation spans email, web, app, and push channels. Performance prediction scores message variants before send to identify predicted champions. Built-in experimental design handles A/B testing and ongoing performance optimization. Multi-language and regional brand calibration supports global Fortune 500 deployments. The vendor-confirmed performance benchmark is a 9.7% median click uplift for predicted champions, rising to 19% with testing over time. The Spring 2025 product release introduced Language² and Neural² capabilities, expanding the platform's content generation and performance modeling depth. Integration depth is extensive: 14 named native integration partners confirmed from the vendor integrations page, covering all major customer engagement platforms and email service providers. Confirmed partners include Adobe, Airship, Bloomreach, Braze, Cordial, Epsilon, Insider, Iterable, Marigold Liveclicker, MessageGears, Moengage, Movable Ink, Optimizely, and Salesforce. The Salesforce Marketing Cloud integration is confirmed through a named customer testimonial on the integrations page and G2 review evidence. Content generated by Jacquard is deployed directly into these platforms for testing, optimization, and delivery. No MCP (Model Context Protocol) server is available for AI assistant connectivity. Jacquard is not the right fit for SMB and mid-market brands, solo content marketers, or teams that need long-form content generation, technical documentation, or social media content at scale. Jasper at $49 per month (Creator) serves content marketers needing AI writing assistance for blog posts, social captions, and marketing copy without the enterprise brand calibration layer. Copy.ai at $29 per month (Chat) covers GTM workflow automation for sales and marketing teams without the channel integration depth. Persado is the closest direct competitor in the enterprise brand language optimization category, also serving Fortune 500 brands with AI-generated marketing language. The two platforms compete directly on brand voice accuracy, integration ecosystem, and proven ROI benchmarks. For mid-market brands wanting email subject line optimization without enterprise commitment, lighter-weight A/B testing tools built into platforms like Klaviyo AI or Braze may be a better starting point. Current state Q3 2026: Jacquard holds ISO 27001 certification confirmed in Section 4 of the published Information Security Addendum at jacquard.com/legal. The security addendum also explicitly prohibits use of client confidential information for any purpose beyond the services contracted, meaning client brand data and campaign content is not used to train shared AI models. GDPR compliance is confirmed through the published Data Processing Addendum and Data Subject Rights provisions in the security documentation. SOC 2 Type II is not listed in the published security addendum. The Jacquard rebrand from Phrasee completed in June 2024, and some G2 and community resources still reference the Phrasee name. Both names refer to the same company and product. G2 reviewers rate Jacquard 4.4 out of 5 across 25 reviews in the AI Writing Assistants category.
