Writer exposes an API for programmatic access, enabling developers to build and deploy agentic AI workflows within their own applications and infrastructure. The platform supports flexibility in model selection — teams can use Writer's proprietary LLMs or connect preferred models. The Knowledge Graph serves as the data-grounding layer, connecting the AI to internal company data sources. Integration is supported across a broad set of enterprise systems (see integrations list), and the platform provides observability and audit controls for monitoring agent behavior and outputs. Writer is a cloud-hosted SaaS product and is not available for self-hosting. Pricing is per-seat with fixed credit limits on the Starter plan; Enterprise plan terms require direct engagement with the sales team.
