WRITER introduces enterprise-specific AI text watermarking controls.

WRITER introduces enterprise-specific AI text watermarking controls. The new watermarking feature lets businesses tailor AI content identification, offering default compliance for EU organisations. WRITER, an AI platform focused on enterprise users, has launched a new method for watermarking AI-generated text that provides companies with greater control over how their digital content is identified and tracked. The system introduces invisible, machine-readable watermarks that are unique to each customer organisation when using text produced by WRITER'S Palmyra models. For customers based in the European Union (EU), text watermarking will be activated automatically and set to comply with the EU AI Act. Clients outside the EU will have the option to enable watermarking and adjust its parameters according to specific business requirements. Traditional industry approaches to AI-generated content watermarking often rely on marking content so that its origin can be traced back to the large language model (LLM) provider, potentially overlooking the role played by enterprises in shaping the output. WRITER'S method embeds an enterprise-specific mark, reflecting input such as brand voice, customer data, business context, and compliance standards. WRITER CEO and co-founder May Habib said: "Enterprises don't want their model providers making their AI decisions for them. They want ownership, control, and configurability, right down to how and when their AI-generated content is watermarked. "The labs' hatchet approach to watermarking is just the latest proof that they don't get the enterprise. They checked the compliance box without a second thought about how customers wanted their content marked. We've built hand-in-hand with the enterprise for six years and that partnership has shaped a very different roadmap." With this system, enterprises can not only turn watermarking on or off but also customise it for specific use cases, subject to regulatory guidelines. The watermark is created by subtly steering the model's word choices, embedding a pattern that is not visible to the human eye but detectable by machines. WRITER customers can adjust watermark strength, balancing detection reliability and content quality. Stronger watermarking may be used for regulated communication, such as by banks or pharmaceutical companies, while marketing teams may prioritise content quality over detection. The platform provides options to apply watermarks to certain types of content while excluding others. The multi-bit watermarking process enables embedding additional custom information, such as marketing or campaign identification, within the text. This function allows customers to trace content reach and distribution, supporting campaign tracking initiatives within their organisations. Give your business an edge with its leading Tech Monitor

WRITER scores highest in capabilities in 2026 IDC MarketScape for Agentic Marketing.

WRITER scores highest in capabilities in 2026 IDC MarketScape for Agentic Marketing. WRITER Team | October 12, 2026 WRITER has received the highest score in capabilities of any vendor in the IDC MarketScape for Worldwide Agentic Marketing - a major recognition in IDC's first report on this category. For a company at its stage, this placement is a strong signal. But what's more interesting about what enterprises need to fuel agentic marketing and growth is what IDC highlighted about its platform. A full-stack platform built organically. IDC recognized WRITER's full-stack approach as a core differentiator - proprietary Palmyra models and governance that gives marketers autonomy with guardrails for brand compliance. That's full control for the enterprise from the model to the application layer. Further, its Palmyra models rank near the top of independent benchmarks for translation and in-context learning, with better inference economics than frontier models. Writer built its own models because Writer didn't want to rent its intelligence from providers who don't understand its enterprise customers. Governance as a differentiator, not a constraint. IDC called out its governance depth: strong controls across the agent lifecycle and at runtime to ensure content compliance with enterprise brand policies. That's the balance the market is looking for - over 60% of buyers rank transparency into business, IT, and security risk above every other requirement. Why this matters now. The conversation has moved from "AI that helps you write" to "AI that does the work." The key factor that many teams still miss is that, no matter how powerful your model is or how many agents you set up to do work, without the proper context, you are deploying generic AI, something that presents a meaningful risk to the brand your organization has spent years or decades building. That's exactly why Writer built the full stack. When you own your models, your data stays yours. When governance is built in, marketers move fast without eroding the brand. You get the autonomy and the guardrails - not just more output, but more you. Agentic marketing is where this shift is happening fastest, and third-party validation from IDC confirms Writer is positioned to lead it. You can read the full report here if you're an IDC customer.

Writer launches Enterprise Brain, a universal context layer powering AI agents across enterprise teams

Writer launched Enterprise Brain, a universal context layer that captures an enterprise's brand, institutional knowledge, and business data for use across teams and AI agents in real time. The platform includes Agent Memory, a team-level memory system, and expanded brand and compliance features. The company also introduced Writer Meet for virtual meetings across Zoom, Microsoft Teams, and Google Meet, plus Writer for Slack and Microsoft Teams. These tools allow teams to activate Writer Agent directly in their workspaces. Enterprise Brain addresses a key challenge: whilst marketing and sales teams shape the customer journey together, 90% report conflicting priorities, according to Gartner. The system captures context from platforms like Salesforce, Snowflake, and Adobe Experience Manager. Fortune 500 companies including Clorox, Labcorp, Qualcomm, and Vanguard already use Writer's platform. Enterprise Brain is available in early access, whilst Writer Meet and Agent Memory are generally available.

Writer launches Enterprise Brain to unify AI agent context.

Writer launches Enterprise Brain to unify AI agent context. SEP 9, 2026 Writer's new context layer aims to give enterprise AI agents shared memory, governance and live business data across marketing and revenue teams. The gist. * Unified context layer. Writer introduces Enterprise Brain for real-time enterprise context sharing. * Team-level AI memory. Agent Memory captures and shares decisions across marketing and revenue teams. * Executive impact. Helps senior marketing and sales leaders ensure consistent customer journeys and brand standards, potentially driving greater revenue alignment. Writer, the AI agent platform for enterprise marketing and revenue teams, on Sept. 9 unveiled Enterprise Brain - a governed, universal context layer that dynamically captures brand knowledge, decision logic and live business data across teams and agents. The San Francisco-based company said the system aims to help enterprises deliver more consistent, on-brand customer journeys. Enterprise Brain launched alongside Agent Memory, a team-level memory layer, and an expanded brand and compliance layer. Writer also released Writer Meet across Zoom, Microsoft Teams and Google Meet, plus integrations for Slack and Microsoft Teams. Enterprise Brain is available in early access for select customers. Writer Meet, Writer for Slack and Agent Memory are generally available now; Writer for Microsoft Teams will follow in coming weeks. "Competitive advantage comes from everything you can't buy off the shelf - the details only you know about your customers, the hard-won judgment that shapes how work gets done, how you win, how you differentiate, your core brand beliefs," said May Habib, co-founder and CEO of Writer. Writer feature breakdown. According to Writer, Enterprise Brain and its companion launches address the following capabilities: | Capability | Description | | Enterprise Brain | Governed context layer mapping accounts, campaigns and customer data in real time | | Agent Memory | Team-level memory capturing decisions and preferences across sessions | | Brand & compliance layer | Encodes messaging, visual identity and sub-brand standards for agent use | | Writer Meet | Captures context from live meetings on Zoom, Teams and Google Meet | | Writer for Slack | Surfaces enterprise context inside Slack conversations | Recent Writer news. Writer has maintained an aggressive product cadence over the past year, culminating in the August 2026 release of Palmyra X6 and a rebuilt Agent harness. The company claims the pairing delivers 52% lower cost, 48% faster speed and 10% higher quality versus prior performance. Since late 2025, Writer shipped Playbooks, Routines and Connectors; a native Amazon Bedrock integration and agent supervision suite; 200-plus enterprise Agent Skills; Event-Based Triggers; and brand-governance infrastructure enforcing voice and style guidelines across marketing workflows. A commissioned Forrester study tied the brand-governance release to an 85% reduction in compliance-review time. Why shared context matters for AI agents. Enterprise AI agents need shared memory, governance controls and system connectors to execute coherent, multi-step customer experience journeys. Notable news & distinguished data for tomorrow's c-suite. AI agents deliver durable value only when they operate on live, shared data rather than static snapshots. As prior CMSWire analysis outlined, context persistence is the precondition for outcome delivery, not mere response generation. Without this layer, agents reset with each session, customers re-introduce themselves and workflows fragment. The result is faster automation that reinforces the data silos that have long fractured customer experience. Governance & cross-agent orchestration. Shared context without governance creates compliance exposure. Governed AI agents constrain large language models with business logic and human-in-the-loop oversight, running policy enforcement and output filtering continuously rather than in batch mode. Effective agentic journeys require coordinated business rules and consistent context across marketing, sales and service. The agentic CX framework adds memory and orchestration layers suited to multi-step engagement. Learning Opportunities Writer background.

WRITER named a Market Shaper in the July 2026 gartner(r) Emerging Market Quadrant(TM) for AI Agents for Marketing - Startup Vendors. The recognition follows a year of platform expansion to empower marketing and revenue teams to reinvent the customer journey with agentic AI Writer Team | August 19, 2026 SAN FRANCISCO - August 19, 2026 - WRITER, the enterprise AI agent platform trusted by the world's leading Fortune 500 brands, today announced it has been recognized as a Market Shaper in the first-ever Gartner Emerging Market Quadrant(TM) for AI Agents for Marketing - Startup Vendors. The recognition follows a year of platform expansion to empower marketing and revenue teams to reinvent the customer journey with agents, including the launch of Palmyra X6, major upgrades to WRITER Agent, and enhanced brand and supervision capabilities that make agentic work on-brand, reliable, and cost-efficient at scale. Emerging Market Quadrants depict fast-evolving markets by using a two-dimensional matrix that evaluates providers based on their Potential for Market Disruption and their Potential to Execute. Market Shapers occupy the upper-right quadrant, which WRITER feels indicates relatively high potential across both dimensions. According to Gartner, "Market Shapers are ushering in a new era of industrialized, autonomous revenue engines, combining enterprise-grade governance, compliance and data security with frontier AI innovation, empowering marketing teams to move beyond pilots to scalable, autonomous agent orchestration as the new standard for modern GTM execution." In WRITER's view, the report captures a critical moment as marketing and revenue teams move beyond automating isolated tasks to reshape the customer journey itself - a shift that requires more than capable models or copilots that make individuals faster. WRITER believes it is at the forefront of this shift, combining powerful agent capabilities with an enterprise-grade platform that turns an organization's expertise into shared infrastructure the whole team can use, connects go-to-market work, and keeps outputs on-brand, compliant, and supervised as agentic AI scales. "Forward-thinking marketing leaders aren't asking for another AI tool that helps one person create one more asset, or makes one person a little faster," said May Habib, co-founder and CEO of WRITER. "They're now looking at the whole customer journey, from the first moment someone discovers their brand through years of relationship management, and asking which partner can help them completely reinvent it. While the rest of the market takes a generic approach to AI, our deep focus on marketing and revenue, coupled with the product foundation we've spent the last five years building, set us up to deliver on that dream for the world's biggest brands." Last week, WRITER released Palmyra X6 and major upgrades to WRITER Agent designed to make complex, multi-step marketing and revenue workflows more cost-efficient and reliable from start to finish. These releases follow major features shipped earlier this year: Playbooks and Skills that make institutional knowledge and repeatable processes available across teams; WRITER's brand suite for voice, terminology, and style; prebuilt connectors to the systems and tools marketing and revenue teams use every day, like Microsoft 365, Salesforce, Snowflake, Adobe, and Google Workspace; and governance controls, including granular permissions, audit trails, and compliance guardrails, that give enterprises the control they need as adoption grows. With WRITER, enterprise teams at Ally Financial, AstraZeneca, Cigna, Comcast, Franklin Templeton, Keurig Dr Pepper, Marriott, Mars, Uber, and Vanguard are enforcing brand and compliance requirements at scale, orchestrating end-to-end campaigns, personalizing customer and account experiences, and managing high-volume relationship workflows in ways that weren't possible before, without losing what makes their brand distinct.
