Writer

Writer is an end-to-end enterprise generative AI platform where teams build, deploy, and supervise AI applications and agents grounded in their company data. It combines Writer's proprietary Palmyra LLMs, graph-based RAG (Knowledge Graph), AI guardrails, and an app/agent builder in a single integrated stack.

Writer is a full-stack generative AI platform built specifically for large enterprises, offering both the foundation model layer and the application layer in one integrated product. Its proprietary Palmyra family of large language models powers general-purpose, vision, and domain-specific use cases (including specialized models such as Palmyra Med and Palmyra Fin), with the long-context Palmyra X5 reasoning model supporting a 1M-token context window. The platform pairs these models with Writer's graph-based RAG technology (Knowledge Graph) for grounding AI in internal data sources, customizable AI guardrails for compliance and safety, observability and reporting, and AI Studio for building no-code and code-based agents and workflows. Trusted by hundreds of large organizations including Accenture, Intuit, Salesforce, Uber, Vanguard, L'Oreal, and Marriott, Writer was founded in 2020 by May Habib and is positioned around delivering measurable enterprise ROI from autonomous, agentic AI deployed securely on the company's own data.
