Writer — Enterprise Agent Platform
Writer differentiates on full-stack ownership: it trains its own Palmyra LLMs, runs its own inference, provides its own agent and knowledge-graph builder, and sells directly to enterprise customers. That stack means deep customization (fine-tuned on your content, grounded in your knowledge graph) and data-residency guarantees that matter in regulated industries. Customers: Accenture, L'Oréal, Vanguard.

Frequently asked questions
Why use Writer's own LLM vs. GPT/Claude?
Three reasons enterprises cite: data stays in Writer's stack (no third-party LLM exposure), fine-tuning on customer content is deeper, and pricing is bundled rather than per-token, which predictably scales for large rollouts.
How do its agents differ from a raw LLM?
Writer Agents combine its LLM with a knowledge-graph RAG layer, brand-voice policies (so output sounds like your company), and task-specific templates (PR drafts, compliance memos) with tracked approvals.
Is it competitive with Glean?
Overlap on grounded-agent use cases, but different center-of-gravity: Writer owns the LLM and leads with brand-voice/compliance; Glean leans on third-party LLMs and leads with enterprise search breadth.
