Writer

Writer is a full-stack generative AI platform built for enterprises rather than individual writers. Its foundation is a family of proprietary large language models called Palmyra, paired with a graph-based retrieval system the company calls a Knowledge Graph, which connects the models to a company's own business data so outputs are grounded in accurate, current information rather than generic web knowledge. On top of this, Writer applies AI guardrails that automatically check generated content for brand consistency, compliance, and inclusivity before it reaches an end user. In 2025 the company launched AI HQ, a hub for orchestrating agent-powered work that includes a low-code Agent Builder, observability tools for monitoring agents in production, and a library of over 100 ready-to-use agents for tasks across finance, healthcare, retail, and technology. Writer also offers developer tools and an API for building custom integrations, plus connectors to Salesforce, Slack, and Google Workspace that let agents read CRM records, search Slack conversations, and automate Gmail, Calendar, Docs, Sheets, and Drive workflows. Writer serves large organizations across product, operations, support, marketing, and HR functions, with customers including Intuit, Spotify, L'Oreal, Uber, and Deloitte. The platform complies with SOC 2 Type II, GDPR, HIPAA, and PCI, and states it does not use customer data to train its models. Writer, Inc. was founded in 2020 by May Habib and Waseem AlShikh, and is based in San Francisco.
