WRITER

WRITER is an enterprise platform for building, deploying and supervising AI agents and generative AI applications inside large organisations, having evolved from an AI writing assistant into full-stack enterprise AI infrastructure. Its central proposition is that enterprises cannot safely adopt general-purpose AI tools without control over what the models know, what they are permitted to say and what they do with company data. WRITER addresses this by running its own family of purpose-built large language models rather than reselling third-party ones, which gives enterprises predictable behaviour, data that is not used to train external models, and deployment options that satisfy security and regulatory review.

The platform has three broad layers. Knowledge Graph connects the models to an organisation's own content — documents, product data, policies, knowledge bases and systems of record — using graph-based retrieval so that generated output is grounded in verified internal information rather than model recollection, substantially reducing fabrication. On top of this, a development environment lets teams build AI agents that execute multi-step business processes: drafting and reviewing regulated content, summarising and analysing documents, answering employee or customer questions, extracting structured data and triggering downstream actions. Both no-code tools for business users and full APIs and SDKs for developers are provided. The supervision layer is what distinguishes an enterprise product from a consumer one: administrators enforce brand voice, terminology, legal and regulatory language rules, and compliance guardrails across every output, with audit trails, usage analytics and access governance showing who used what and how it performed. The original writing assistance capability persists, available within Word, Google Docs, browsers and collaboration tools, applying an organisation's style guide consistently across everyone who writes. WRITER is used in financial services, healthcare, technology, retail and consulting. Pricing starts from around USD 39 per user per month with a free trial, rising to enterprise agreements; no free version.
