How it works
Three steps to reliable, repeatable content delivery.
Define your brand and cadence
Configure voice, topics, and publishing schedules. Postility encodes these as explicit rules to ensure consistency across all outputs.
Agents generate and validate content
Deterministic, multi-step workflows produce on-brand content with built-in quality and brand checks.
Deliver via API or integrations
Deliver content to your CMS, social platforms, or internal tools via API. Every step is programmable, versioned, and auditable.
What Postility actually does
Content generation treated as an engineering problem, not a writing problem.
Deterministic workflows
Content is produced through multi-step agent pipelines: brand normalization, brief planning, outlining, drafting, QA checks, and delivery. Each step enforces strict input and output schemas.
Separated responsibilities
Planning, drafting, QA, and delivery are handled by specialized agents. Each agent has a single responsibility. Failures are isolated, observable, and retriable.
Backend-native
Your content pipeline inherits the reliability characteristics of your infrastructure.
Reliability guarantees
Your content pipeline inherits the reliability characteristics of your infrastructure.
Postility vs prompt-based tools
Prompt-based tools are designed for exploration. Postility is designed for production workflows.
The difference: Prompt tools require a human in the loop. Postility runs unattended, on schedule, with guarantees.
What Postility is not
Clear boundaries help you understand if Postility is right for your use case.
Not a writing assistant
No chat interface. No prompt box. Postility is infrastructure, not a tool you interact with manually.
Not a ChatGPT wrapper
Postility uses multiple specialized agents with strict schemas between steps. It's a workflow engine, not a prompt relay.
Not a CMS
Postility generates and delivers content. It doesn't store or manage your content library. It integrates with your existing CMS.
